 # Routstr Payment Proxy
 
-Routstr is a FastAPI-based reverse proxy that sits in front of any OpenAI-compatible API. It handles pay-per-request billing using the [Cashu](https://cashu.space/) eCash protocol on Bitcoin and tracks usage in a local SQL database.

-The server exposes the same endpoints as the upstream API and deducts sats from user accounts for each call. Pricing can be static or model-specific by loading `models.json` (falls back to `models.example.json`).
+Routstr is a decentralized protocol for permissionless, private, and censorship-resistant AI inference. It combines Nostr for discovery and Cashu for private Bitcoin micropayments.
 
-## How It Works
+This repo contains Routstr Core: a FastAPI-based reverse proxy that sits in front of OpenAI-compatible APIs and handles pay-per-request billing.
 
-The proxy implements a seamless eCash payment flow that maintains compatibility with existing OpenAI clients while enabling Bitcoin micropayments:

+## Basic Usage
+
+If you are a user/developer, you just point an OpenAI-compatible SDK at a Routstr node and pay with a Cashu token.
+
+### OpenAI SDK
+
+```python
+from openai import OpenAI
+
+client = OpenAI(
+    base_url="https://api.routstr.com/v1",
+    api_key="cashuBo2FteCJodHRwczovL21...",
+)
+
+response = client.chat.completions.create(
+    model="gpt-5-nano",
+    messages=[{"role": "user", "content": "hello"}],
+)
+
+print(response.choices[0].message.content)
 ```

+  -d '{
+    "model": "gpt-5-nano",
+    "messages": [{"role": "user", "content": "hello"}]
+  }'
+```
 
-## Getting Started
+## Quick Start (Docker)
 
-### Running the proxy using Docker
+If you are a node runner, start a Routstr Core instance and configure upstream access in the dashboard.
 
 ```bash
 docker run -d \
---name routstr-proxy \
--p 8000:8000 \
--e UPSTREAM_BASE_URL=https://api.openai.com/v1 \
--e UPSTREAM_API_KEY=your-openai-api-key \
-ghcr.io/routstr/proxy:latest
+  --name routstr-proxy \
+  -p 8000:8000 \
+  ghcr.io/routstr/proxy:latest
 ```
 
-### Development Requirements
-
-- Python 3.11+
-- [uv](https://github.com/astral-sh/uv) package manager (used in development)
-
-### Installation
-
-```bash
-uv sync  # install dependencies
-```
-
-Create a `.env` file based on `.env.example` and fill in the required values:
+## Development
 
 ```bash
+make setup
 cp .env.example .env
+fastapi run routstr
 ```
-
-### Running Locally
-
-```bash
-fastapi run routstr --host 0.0.0.0 --port 8000
-```
-
-The service forwards requests to `UPSTREAM_BASE_URL`. Supply the upstream API key via the `UPSTREAM_API_KEY` environment variable if required.
-
-### Docker
-
-```bash
-docker compose up --build
-```
-
-This builds the image and also starts a Tor container exposing the API as a hidden service.
-
-## Environment Variables
-
-The most common settings are shown below. See `.env.example` for the full list.
-
-### Core Settings
-
-- `UPSTREAM_BASE_URL` – URL of the OpenAI-compatible service
-- `UPSTREAM_API_KEY` – API key for the upstream service (optional)
-- `FIXED_PRICING` – Set to `true` to use a fixed per-request price; `false` (default) uses model pricing from `models.json`
-- `ADMIN_PASSWORD` – Password for the `/admin/` dashboard
-- `CASHU_MINTS` – Comma-separated list of Cashu mint URLs
-- `NAME` – Name of the proxy
-- `DESCRIPTION` – Description of the proxy
-- `NPUB` – Nostr public key of the proxy
-- `HTTP_URL` – Public-facing URL of the proxy
-- `ONION_URL` – Tor hidden service URL of the proxy
-- `NEXT_PUBLIC_API_URL` - UI Configuration for Next.js frontend (proxy URL, default: 'http://127.0.0.1:8000' )
-
-## Database Migrations
-
-The application uses Alembic for database schema management and **automatically runs migrations on startup**. This ensures your database is always up-to-date when deploying new versions.
-
-### Automatic Migrations in Production
-
-When the FastAPI application starts, it automatically:
-
-1. Runs all pending database migrations
-2. Updates the schema to the latest version
-3. Logs the migration status
-
-This means you don't need to manually run migrations when deploying - just restart the application and migrations will be applied automatically.
-
-### Manual Migration Commands
-
-For development or troubleshooting, you can use these Makefile commands:
-
-```bash
-make db-upgrade         # Apply all pending migrations
-make db-downgrade       # Downgrade one migration
-make db-current         # Show current migration revision
-make db-history         # Show migration history
-make db-migrate         # Auto-generate new migration from model changes
-make db-revision        # Create empty migration file
-make db-heads           # Show current migration heads
-make db-clean           # Clean migration cache files
-```
-
-### Creating New Migrations
-
-When you modify SQLModel models:
-
-```bash
-# Auto-generate a migration from model changes
-make db-migrate
-# Enter a descriptive message when prompted
-
-# Review the generated migration file in migrations/versions/
-# Edit if needed, then test with:
-make db-upgrade
-```
-
-## Admin UI
-
-Routstr includes a modern Next.js admin dashboard that's served directly from the Python backend as static files - no separate Node.js server required.
-
-### Building the UI
-
-```bash
-make ui-build
-```
-
-This compiles the Next.js application into static HTML, CSS, and JavaScript files in `ui/out/`.
-
-### Accessing the Dashboard
-
-Once built, the UI is automatically served by the FastAPI backend:
-
-- **Dashboard**: `http://localhost:8000/`
-- **Login**: `http://localhost:8000/login`
-- **Models Management**: `http://localhost:8000/model`
-- **Providers Management**: `http://localhost:8000/providers`
-- **Settings**: `http://localhost:8000/settings`
-
-The dashboard provides:
-
-- Real-time wallet balance monitoring
-- Model pricing configuration
-- Upstream provider management
-- Transaction history
-- System settings
-
-**Authentication**: Use the `ADMIN_PASSWORD` environment variable to access the dashboard.
-
-## Withdrawing Balance
-
-Go to the admin dashboard at `http://localhost:8000/` and login with your `ADMIN_PASSWORD` to withdraw your balance as a Cashu token.
-
-## Example Client
-
-`example.py` shows how to use the proxy with the official OpenAI client:
-
-```bash
-CASHU_TOKEN=<redeemable token> python example.py
-```
-
-The script sends streaming chat completions and pays for each request using the provided token.
-
-## Running Tests
-
-```bash
-uv run pytest
-```
-
-The tests create a temporary SQLite database and mock the Cashu wallet. See `tests/README.md` for more details.
-
-## Future Features
-
-### Nut-24 Header Support (Coming Soon)
-
-We're implementing support for the Cashu Nut-24 specification, which will enable per-request token exchange with automatic change handling:
-
-```mermaid
-graph TD
-    A["Client Request<br/>x-cashu: token"] --> B[Proxy Validates Token]
-    B --> C{Token ≥ Minimum Amount?}
-    C -->|No| F[Return 402 Payment Required]
-    C -->|Yes| D[Calculate Request Cost]
-    D --> E[Process Request]
-    E --> G[Forward to Upstream API]
-    G --> H[Receive API Response]
-    H --> I[Calculate Change]
-    I --> J["Return Response<br/>x-cashu: change_token"]
-    F --> K[End]
-    J --> K
-```
-
-**Key Benefits:**
-
-- **Per-Request Payments** – Send exact tokens for each API call
-- **Automatic Change** – Receive change tokens in response headers
-- **No Pre-funding** – No need to maintain account balances
-- **Precise Billing** – Pay only for actual usage with msat-level precision
-- **Minimum Amount Protection** – Proxy enforces minimum token value to prevent dust attacks
-
-**Header Format:**
-
-- **Request**: `x-cashu: <ecash_token>` – Token to spend for this request (must meet minimum amount)
-- **Response**: `x-cashu: <change_token>` – Change token if payment exceeds cost
-
-**Implementation Note:**
-The proxy should implement either a dedicated endpoint to communicate minimum eCash requirements per request, or extend the existing `models.json` to include minimum token amounts per model. This allows clients to autonomously determine the appropriate token amount to send with each request.
-
-**Compatible Clients:**
-
-To use this feature, you'll need a client that handles both OpenAI API calls and eCash header management. The following clients provide seamless integration:
-
-- **[routstr-chat](https://github.com/routstr/routstr-chat)** – chat app for the routstr network
-- **[otrta-client](https://github.com/routstr/otrta-client)** – rust web app for the routstr network
-
-clients automatically:
-
-- **Handle eCash Headers** – Add `x-cashu` tokens to requests and process change tokens
-- **Manage Wallets** – Maintain your Cashu wallet
-- **Configure Proxy** – Set Routstr proxy endpoints
-- **Top-up Balances** – Automatically request ecash when tokens run low and redeem ecash tokens
-
-This approach eliminates the need for account management while maintaining the security and privacy benefits of eCash payments.

-# Custom Pricing
-
-This guide covers advanced pricing strategies and customization options for Routstr Core.
-
-## Pricing Models Overview
-
-Routstr supports three pricing models:
-
-1. **Fixed Pricing** - Simple per-request fee
-2. **Token-Based Pricing** - Charge per input/output token
-3. **Model-Based Pricing** - Dynamic pricing from models.json
-
-## Model-Based Pricing
-
-### Configuration
-
-Enable model-based pricing (default behavior):
-
-```bash
-# .env
-FIXED_PRICING=false
-MODELS_PATH=/app/config/models.json
-EXCHANGE_FEE=1.005         # 0.5% exchange fee
-UPSTREAM_PROVIDER_FEE=1.05  # 5% provider margin
-```
-
-### Custom Models File
-
-Create a `models.json` with your pricing:
-
-```json
-{
-  "models": [
-    {
-      "id": "gpt-4",
-      "name": "GPT-4",
-      "description": "Advanced reasoning model",
-      "context_length": 8192,
-      "pricing": {
-        "prompt": "0.03",        // USD per 1K tokens
-        "completion": "0.06",    // USD per 1K tokens
-        "request": "0.0001",     // Fixed per-request fee
-        "image": "0",            // For multimodal models
-        "web_search": "0.005",   // Additional features
-        "internal_reasoning": "0.01"
-      },
-      "supported_features": [
-        "function_calling",
-        "vision",
-        "json_mode"
-      ],
-      "deprecation_date": null,
-      "replacement_model": null
-    },
-    {
-      "id": "custom-model",
-      "name": "Custom Fine-tuned Model",
-      "pricing": {
-        "prompt": "0.001",
-        "completion": "0.002",
-        "request": "0.00005"
-      },
-      "minimum_charge": "0.0001"  // Minimum charge per request
-    }
-  ],
-  "default_pricing": {
-    "prompt": "0.002",
-    "completion": "0.002",
-    "request": "0"
-  }
-}
-```
-
-### Dynamic Price Updates
-
-Automatically fetch prices from providers:
-
-```python
-# scripts/update_prices.py
-import asyncio
-import httpx
-import json
-
-async def fetch_openrouter_models():
-    """Fetch current model pricing from OpenRouter."""
-    async with httpx.AsyncClient() as client:
-        response = await client.get(
-            "https://openrouter.ai/api/v1/models"
-        )
-        return response.json()
-
-async def update_models_json():
-    """Update local models.json with latest prices."""
-    data = await fetch_openrouter_models()
-    
-    models = []
-    for model in data['data']:
-        models.append({
-            "id": model['id'],
-            "name": model['name'],
-            "pricing": {
-                "prompt": model['pricing']['prompt'],
-                "completion": model['pricing']['completion'],
-                "request": model['pricing'].get('request', '0')
-            },
-            "context_length": model.get('context_length', 4096)
-        })
-    
-    with open('models.json', 'w') as f:
-        json.dump({"models": models}, f, indent=2)
-
-# Run periodically
-if __name__ == "__main__":
-    asyncio.run(update_models_json())
-```
-
-## Token-Based Pricing
-
-### Configuration
-
-Set up token-based pricing overrides:
-
-```bash
-# .env
-FIXED_PRICING=false                 # use model pricing
-FIXED_COST_PER_REQUEST=1            # optional base fee
-FIXED_PER_1K_INPUT_TOKENS=5         # optional override
-FIXED_PER_1K_OUTPUT_TOKENS=15       # optional override
-```
-
-### Custom Token Counting
-
-Override default token counting:
-
-```python
-from tiktoken import encoding_for_model
-
-class CustomTokenCounter:
-    def __init__(self):
-        self.encodings = {}
-    
-    def count_tokens(
-        self, 
-        text: str, 
-        model: str
-    ) -> int:
-        """Custom token counting logic."""
-        # Cache encodings
-        if model not in self.encodings:
-            try:
-                self.encodings[model] = encoding_for_model(model)
-            except:
-                # Fallback encoding
-                self.encodings[model] = encoding_for_model("gpt-3.5-turbo")
-        
-        encoding = self.encodings[model]
-        
-        # Special handling for certain content
-        if text.startswith("```"):
-            # Code blocks might need special handling
-            tokens = encoding.encode(text)
-            return len(tokens) * 1.1  # 10% markup for code
-        
-        return len(encoding.encode(text))
-```
-
-## Advanced Pricing Strategies
-
-### Time-Based Pricing
-
-Implement peak/off-peak pricing:
-
-```python
-from datetime import datetime
-import pytz
-
-class TimeBased PricingStrategy:
-    def __init__(self):
-        self.timezone = pytz.timezone('US/Eastern')
-        self.peak_hours = [(9, 17)]  # 9 AM - 5 PM
-        self.peak_multiplier = 1.5
-        self.weekend_discount = 0.8
-    
-    def get_price_multiplier(self) -> float:
-        """Calculate price multiplier based on time."""
-        now = datetime.now(self.timezone)
-        
-        # Weekend discount
-        if now.weekday() >= 5:  # Saturday or Sunday
-            return self.weekend_discount
-        
-        # Peak hours surcharge
-        hour = now.hour
-        for start, end in self.peak_hours:
-            if start <= hour < end:
-                return self.peak_multiplier
-        
-        # Off-peak standard pricing
-        return 1.0
-    
-    def apply_to_cost(self, base_cost: int) -> int:
-        """Apply time-based pricing to cost."""
-        multiplier = self.get_price_multiplier()
-        return int(base_cost * multiplier)
-```
-
-### Model-Specific Surcharges
-
-Add custom fees for specific models:
-
-```python
-class ModelSurchargeStrategy:
-    def __init__(self):
-        self.surcharges = {
-            "gpt-4-turbo": 1.1,      # 10% premium
-            "claude-3-opus": 1.15,    # 15% premium
-            "dall-e-3-hd": 1.25,      # 25% premium for HD
-        }
-        
-        self.discounts = {
-            "gpt-3.5-turbo": 0.95,    # 5% discount
-            "deprecated-model": 0.8,   # 20% discount
-        }
-    
-    def get_model_multiplier(self, model: str) -> float:
-        """Get price multiplier for model."""
-        if model in self.surcharges:
-            return self.surcharges[model]
-        elif model in self.discounts:
-            return self.discounts[model]
-        return 1.0
-```
-
-### Geographic Pricing
-
-Adjust pricing based on client location:
-
-```python
-import geoip2.database
-
-class GeographicPricingStrategy:
-    def __init__(self):
-        self.reader = geoip2.database.Reader('GeoLite2-Country.mmdb')
-        self.country_multipliers = {
-            'US': 1.0,
-            'GB': 1.0,
-            'DE': 1.0,
-            'IN': 0.7,  # 30% discount
-            'BR': 0.8,  # 20% discount
-            'NG': 0.6,  # 40% discount
-        }
-        self.default_multiplier = 0.9
-    
-    def get_country_multiplier(self, ip_address: str) -> float:
-        """Get price multiplier based on country."""
-        try:
-            response = self.reader.country(ip_address)
-            country_code = response.country.iso_code
-            return self.country_multipliers.get(
-                country_code, 
-                self.default_multiplier
-            )
-        except:
-            return 1.0  # Default pricing if lookup fails
-```

-## Troubleshooting
-
-### Price Calculation Issues
-
-```python
-# Debug pricing
-async def debug_price_calculation(
-    model: str,
-    tokens: dict,
-    api_key_id: int
-):
-    """Debug price calculation step by step."""
-    print(f"Model: {model}")
-    print(f"Tokens: {tokens}")
-    
-    # Base price
-    base_price = get_model_price(model)
-    print(f"Base price: {base_price}")
-    
-    # Token cost
-    token_cost = calculate_token_cost(base_price, tokens)
-    print(f"Token cost: {token_cost}")
-    
-    # Strategies
-    strategies = get_active_strategies()
-    for strategy in strategies:
-        multiplier = await strategy.get_multiplier(api_key_id)
-        print(f"{strategy.name}: {multiplier}x")
-    
-    # Final cost
-    final_cost = apply_all_strategies(token_cost, api_key_id)
-    print(f"Final cost: {final_cost} msats")
-    
-    return final_cost
-```
-
-### Common Issues
-
-1. **Prices Not Updating**
-   - Check `MODELS_PATH` is correct
-   - Verify file permissions
-   - Check background task logs
-
-2. **Wrong Currency Conversion**
-   - Verify BTC/USD rate source
-   - Check `EXCHANGE_FEE` setting
-   - Monitor rate update frequency
-
-3. **Discounts Not Applied**
-   - Verify strategy configuration
-   - Check API key metadata
-   - Review transaction history
-
-## Best Practices
-
-1. **Transparent Pricing**
-   - Publish pricing clearly
-   - Show cost breakdowns
-   - Notify of price changes
-
-2. **Fair Pricing**
-   - Regular competitive analysis
-   - Consider user feedback
-   - Offer budget options
-
-3. **Performance**
-   - Cache price calculations
-   - Optimize database queries
-   - Monitor calculation time

-# Database Migrations
-
-This guide covers database schema management using Alembic migrations in Routstr Core.
-
-## Overview
-
-Routstr uses Alembic for database migrations with these features:
-
-- **Automatic migrations** on startup
-- **Version control** for schema changes
-- **Rollback capability** for safety
-- **Support for multiple databases** (SQLite, PostgreSQL)
-
-## Automatic Migrations
-
-### Startup Behavior
-
-Migrations run automatically when Routstr starts:
-
-```python
-# In routstr/core/main.py
-@asynccontextmanager
-async def lifespan(_: FastAPI) -> AsyncGenerator[None, None]:
-    logger.info("Running database migrations")
-    run_migrations()  # Automatic migration
-    await init_db()   # Initialize connection pool
-    # ... rest of startup
-```
-
-This ensures:
-
-- ✅ Database is always up-to-date
-- ✅ No manual migration steps in production
-- ✅ Zero-downtime deployments
-- ✅ Backwards compatibility
-
-### Migration Safety
-
-Migrations are designed to be safe:
-
-- Idempotent (can run multiple times)
-- Non-destructive by default
-- Tested before release
-- Reversible when possible
-
-## Creating Migrations
-
-### Auto-generating from Models
-
-After modifying SQLModel classes:
-
-```bash
-# Generate migration from model changes
-make db-migrate
-
-# You'll be prompted for a description
-Enter migration message: Add user preferences table
-
-# Review generated file
-cat migrations/versions/xxxx_add_user_preferences_table.py
-```
-
-### Manual Migrations
-
-For complex changes, create manually:
-
-```bash
-# Create empty migration
-alembic revision -m "Complex data transformation"
-
-# Edit the generated file
-vim migrations/versions/xxxx_complex_data_transformation.py
-```
-
-### Migration Template
-
-```python
-"""Add user preferences table
-
-Revision ID: a1b2c3d4e5f6
-Revises: f6e5d4c3b2a1
-Create Date: 2024-01-15 10:30:00.123456
-
-"""
-from alembic import op
-import sqlalchemy as sa
-import sqlmodel
-
-# revision identifiers
-revision = 'a1b2c3d4e5f6'
-down_revision = 'f6e5d4c3b2a1'
-branch_labels = None
-depends_on = None
-
-def upgrade() -> None:
-    """Apply migration."""
-    # Create new table
-    op.create_table(
-        'userpreferences',
-        sa.Column('id', sa.Integer(), nullable=False),
-        sa.Column('api_key_id', sa.Integer(), nullable=False),
-        sa.Column('theme', sa.String(), nullable=True),
-        sa.Column('notifications_enabled', sa.Boolean(), default=True),
-        sa.Column('created_at', sa.DateTime(), nullable=False),
-        sa.PrimaryKeyConstraint('id'),
-        sa.ForeignKeyConstraint(['api_key_id'], ['apikey.id'], )
-    )
-    
-    # Create index
-    op.create_index(
-        'ix_userpreferences_api_key_id',
-        'userpreferences',
-        ['api_key_id']
-    )
-
-def downgrade() -> None:
-    """Revert migration."""
-    op.drop_index('ix_userpreferences_api_key_id', table_name='userpreferences')
-    op.drop_table('userpreferences')
-```
-
-## Common Migration Patterns
-
-### Adding Columns
-
-Add column with default value:
-
-```python
-def upgrade():
-    # Add nullable column first
-    op.add_column(
-        'apikey',
-        sa.Column('last_rotation', sa.DateTime(), nullable=True)
-    )
-    
-    # Populate existing rows
-    connection = op.get_bind()
-    connection.execute(
-        "UPDATE apikey SET last_rotation = created_at WHERE last_rotation IS NULL"
-    )
-    
-    # Make non-nullable if needed
-    op.alter_column('apikey', 'last_rotation', nullable=False)
-```
-
-### Renaming Columns
-
-Safe column rename:
-
-```python
-def upgrade():
-    # SQLite doesn't support ALTER COLUMN, so we need a workaround
-    with op.batch_alter_table('apikey') as batch_op:
-        batch_op.alter_column('old_name', new_column_name='new_name')
-```
-
-### Adding Indexes
-
-Performance-improving indexes:
-
-```python
-def upgrade():
-    # Single column index
-    op.create_index(
-        'ix_transaction_timestamp',
-        'transaction',
-        ['timestamp']
-    )
-    
-    # Composite index
-    op.create_index(
-        'ix_transaction_key_time',
-        'transaction',
-        ['api_key_id', 'timestamp']
-    )
-    
-    # Partial index (PostgreSQL only)
-    op.create_index(
-        'ix_apikey_active',
-        'apikey',
-        ['balance'],
-        postgresql_where='balance > 0'
-    )
-```
-
-### Data Migrations
-
-Transform existing data:
-
-```python
-def upgrade():
-    # Add new column
-    op.add_column(
-        'apikey',
-        sa.Column('key_type', sa.String(), nullable=True)
-    )
-    
-    # Migrate data
-    connection = op.get_bind()
-    result = connection.execute('SELECT id, metadata FROM apikey')
-    
-    for row in result:
-        key_type = 'premium' if row.metadata.get('premium') else 'standard'
-        connection.execute(
-            f"UPDATE apikey SET key_type = '{key_type}' WHERE id = {row.id}"
-        )
-    
-    # Make column non-nullable
-    op.alter_column('apikey', 'key_type', nullable=False)
-```
-
-### Enum Types
-
-Add enum column:
-
-```python
-from enum import Enum
-
-class KeyStatus(str, Enum):
-    ACTIVE = "active"
-    SUSPENDED = "suspended"
-    EXPIRED = "expired"
-
-def upgrade():
-    # Create enum type (PostgreSQL)
-    key_status_enum = sa.Enum(KeyStatus, name='keystatus')
-    key_status_enum.create(op.get_bind(), checkfirst=True)
-    
-    # Add column
-    op.add_column(
-        'apikey',
-        sa.Column(
-            'status',
-            key_status_enum,
-            nullable=False,
-            server_default='active'
-        )
-    )
-```
-
-## Database-Specific Considerations
-
-### SQLite Limitations
-
-SQLite has limitations requiring workarounds:
-
-```python
-def upgrade():
-    # SQLite doesn't support ALTER COLUMN directly
-    # Use batch_alter_table for compatibility
-    with op.batch_alter_table('apikey') as batch_op:
-        batch_op.alter_column(
-            'balance',
-            type_=sa.BigInteger(),  # Change from Integer
-            existing_type=sa.Integer()
-        )
-```
-
-### PostgreSQL Features
-
-Leverage PostgreSQL-specific features:
-
-```python
-def upgrade():
-    # Use JSONB for better performance
-    op.add_column(
-        'apikey',
-        sa.Column('metadata', sa.JSON().with_variant(
-            sa.dialects.postgresql.JSONB(), 'postgresql'
-        ))
-    )
-    
-    # Add GIN index for JSONB queries
-    op.create_index(
-        'ix_apikey_metadata',
-        'apikey',
-        ['metadata'],
-        postgresql_using='gin'
-    )
-    
-    # Add check constraint
-    op.create_check_constraint(
-        'ck_apikey_balance_positive',
-        'apikey',
-        'balance >= 0'
-    )
-```
-
-## Migration Commands
-
-### Running Migrations
-
-```bash
-# Apply all pending migrations
-make db-upgrade
-
-# Upgrade to specific revision
-alembic upgrade a1b2c3d4e5f6
-
-# Upgrade one revision
-alembic upgrade +1
-```
-
-### Checking Status
-
-```bash
-# Show current revision
-make db-current
-# Output: a1b2c3d4e5f6 (head)
-
-# Show migration history
-make db-history
-# Output:
-# a1b2c3d4e5f6 -> b2c3d4e5f6a7 (head), Add user preferences
-# f6e5d4c3b2a1 -> a1b2c3d4e5f6, Add indexes
-# e5d4c3b2a1f6 -> f6e5d4c3b2a1, Initial schema
-```
-
-### Rolling Back
-
-```bash
-# Rollback one migration
-make db-downgrade
-
-# Rollback to specific revision
-alembic downgrade f6e5d4c3b2a1
-
-# Rollback all (dangerous!)
-alembic downgrade base
-```
-
-## Testing Migrations
-
-### Unit Testing
-
-Test migrations in isolation:
-
-```python
-import pytest
-from alembic import command
-from alembic.config import Config
-from sqlalchemy import create_engine, inspect
-
-def test_migration_add_user_preferences():
-    """Test user preferences migration."""
-    # Create test database
-    engine = create_engine("sqlite:///:memory:")
-    
-    # Run migrations up to previous version
-    alembic_cfg = Config("alembic.ini")
-    alembic_cfg.set_main_option("sqlalchemy.url", str(engine.url))
-    command.upgrade(alembic_cfg, "f6e5d4c3b2a1")
-    
-    # Verify state before migration
-    inspector = inspect(engine)
-    tables = inspector.get_table_names()
-    assert "userpreferences" not in tables
-    
-    # Run target migration
-    command.upgrade(alembic_cfg, "a1b2c3d4e5f6")
-    
-    # Verify state after migration
-    inspector = inspect(engine)
-    tables = inspector.get_table_names()
-    assert "userpreferences" in tables
-    
-    # Check columns
-    columns = {col['name'] for col in inspector.get_columns('userpreferences')}
-    assert columns == {'id', 'api_key_id', 'theme', 'notifications_enabled', 'created_at'}
-    
-    # Test downgrade
-    command.downgrade(alembic_cfg, "f6e5d4c3b2a1")
-    inspector = inspect(engine)
-    tables = inspector.get_table_names()
-    assert "userpreferences" not in tables
-```
-
-### Integration Testing
-
-Test with real data:
-
-```python
-async def test_migration_with_data():
-    """Test migration preserves existing data."""
-    # Setup test database with data
-    async with test_engine.begin() as conn:
-        # Insert test data
-        await conn.execute(
-            "INSERT INTO apikey (key_hash, balance) VALUES ('test', 1000)"
-        )
-    
-    # Run migration
-    run_migrations()
-    
-    # Verify data integrity
-    async with test_engine.connect() as conn:
-        result = await conn.execute("SELECT * FROM apikey WHERE key_hash = 'test'")
-        row = result.first()
-        assert row.balance == 1000
-        assert row.key_type == 'standard'  # New column with default
-```
-
-## Production Deployment
-
-### Zero-Downtime Migrations
-
-Strategy for seamless updates:
-
-1. **Make migrations backwards compatible**
-
-   ```python
-   # Good: Add nullable column
-   op.add_column('apikey', sa.Column('new_field', sa.String(), nullable=True))
-   
-   # Bad: Drop column immediately
-   # op.drop_column('apikey', 'old_field')
-   ```
-
-2. **Deploy in phases**
-
-   ```bash
-   # Phase 1: Deploy code that works with both schemas
-   # Phase 2: Run migration
-   # Phase 3: Deploy code that requires new schema
-   # Phase 4: Clean up deprecated columns
-   ```
-
-3. **Use feature flags**
-
-   ```python
-   if feature_enabled('use_new_schema'):
-       # Use new column
-       query = select(APIKey.new_field)
-   else:
-       # Use old column
-       query = select(APIKey.old_field)
-   ```
-
-### Migration Monitoring
-
-Track migration execution:
-
-```python
-# Add to migration
-def upgrade():
-    start_time = time.time()
-    logger.info(f"Starting migration {revision}")
-    
-    try:
-        # Migration logic here
-        op.create_table(...)
-        
-        duration = time.time() - start_time
-        logger.info(f"Migration {revision} completed in {duration:.2f}s")
-    except Exception as e:
-        logger.error(f"Migration {revision} failed: {e}")
-        raise
-```
-
-### Backup Before Migration
-
-Always backup before major changes:
-
-```bash
-#!/bin/bash
-# backup_before_migration.sh
-
-# Backup database
-if [[ "$DATABASE_URL" == *"sqlite"* ]]; then
-    cp database.db "backup_$(date +%Y%m%d_%H%M%S).db"
-else
-    pg_dump $DATABASE_URL > "backup_$(date +%Y%m%d_%H%M%S).sql"
-fi
-
-# Run migration
-alembic upgrade head
-
-# Verify
-alembic current
-```
-
-## Troubleshooting
-
-### Common Issues
-
-**Migration Conflicts**
-
-```bash
-# Multiple heads detected
-alembic heads
-# a1b2c3d4e5f6 (head)
-# b2c3d4e5f6a7 (head)
-
-# Merge heads
-alembic merge -m "Merge migrations" a1b2c3 b2c3d4
-```
-
-**Failed Migration**
-
-```python
-# Add rollback logic
-def upgrade():
-    try:
-        op.create_table(...)
-    except Exception as e:
-        # Clean up partial changes
-        op.drop_table('partial_table', checkfirst=True)
-        raise
-
-def downgrade():
-    # Ensure clean rollback
-    op.drop_table('new_table', checkfirst=True)
-```
-
-**Lock Timeout**
-
-```python
-# Add timeout handling
-def upgrade():
-    connection = op.get_bind()
-    
-    # Set timeout (PostgreSQL)
-    connection.execute("SET lock_timeout = '10s'")
-    
-    try:
-        op.add_column(...)
-    except OperationalError as e:
-        if 'lock timeout' in str(e):
-            logger.error("Migration failed due to lock timeout")
-            raise
-```
-
-### Recovery Procedures
-
-If migration fails in production:
-
-1. **Check current state**
-
-   ```bash
-   alembic current
-   alembic history
-   ```
-
-2. **Manual rollback if needed**
-
-   ```sql
-   -- Check migration table
-   SELECT * FROM alembic_version;
-   
-   -- Force version if necessary
-   UPDATE alembic_version SET version_num = 'previous_version';
-   ```
-
-3. **Fix and retry**
-
-   ```bash
-   # Fix migration file
-   vim migrations/versions/problematic_migration.py
-   
-   # Retry
-   alembic upgrade head
-   ```
-
-## Best Practices
-
-### Migration Guidelines
-
-1. **Keep migrations small and focused**
-   - One logical change per migration
-   - Easier to review and rollback
-
-2. **Test migrations thoroughly**
-   - Test upgrade and downgrade
-   - Test with production-like data
-   - Test database-specific features
-
-3. **Document breaking changes**
-
-   ```python
-   """BREAKING: Change balance column type
-   
-   This migration requires application update.
-   Deploy order:
-   1. Update application to handle both int and bigint
-   2. Run this migration
-   3. Update application to use only bigint
-   """
-   ```
-
-4. **Make migrations idempotent**
-
-   ```python
-   def upgrade():
-       # Check if column exists
-       inspector = inspect(op.get_bind())
-       columns = [col['name'] for col in inspector.get_columns('apikey')]
-       
-       if 'new_column' not in columns:
-           op.add_column(
-               'apikey',
-               sa.Column('new_column', sa.String())
-           )
-   ```
-
-### Performance Considerations
-
-1. **Add indexes concurrently (PostgreSQL)**
-
-   ```python
-   def upgrade():
-       # Create index without locking table
-       op.create_index(
-           'ix_large_table_column',
-           'large_table',
-           ['column'],
-           postgresql_concurrently=True
-       )
-   ```
-
-2. **Batch large updates**
-
-   ```python
-   def upgrade():
-       connection = op.get_bind()
-       
-       # Process in batches
-       batch_size = 1000
-       offset = 0
-       
-       while True:
-           result = connection.execute(
-               f"UPDATE apikey SET processed = true "
-               f"WHERE id IN (SELECT id FROM apikey WHERE processed = false LIMIT {batch_size})"
-           )
-           
-           if result.rowcount == 0:
-               break
-               
-           offset += batch_size
-           time.sleep(0.1)  # Prevent overload
-   ```

-# Nostr Discovery
-
-Routstr Core integrates with Nostr (Notes and Other Stuff Transmitted by Relays) for decentralized provider discovery. This enables users to find Routstr nodes without relying on centralized directories.
-
-## Overview
-
-Nostr integration provides:
-
-- **Decentralized Discovery**: Find providers through relay network
-- **Cryptographic Identity**: Providers identified by public keys
-- **Real-time Updates**: Live provider status and pricing
-- **Censorship Resistance**: No central point of control
-
-## How It Works
-
-```mermaid
-graph LR
-    A[Routstr Node] --> B[Nostr Relay]
-    B --> C[Nostr Relay]
-    B --> D[Nostr Relay]
-    
-    E[User Client] --> B
-    E --> C
-    E --> D
-    
-    B --> F[Provider List]
-    C --> F
-    D --> F
-```
-
-Providers announce themselves by publishing signed events to Nostr relays. Clients can query these relays to discover available providers.
-
-## Provider Configuration
-
-### Setting Up Nostr Identity
-
-1. **Generate Nostr Keys**
-
-   ```bash
-   # Using nostril or similar tool
-   nostril --generate-keypair
-   
-   # Output:
-   # Private key (nsec): nsec1abc...
-   # Public key (npub): npub1xyz...
-   ```
-
-2. **Configure Environment**
-
-   ```bash
-   # .env
-   NPUB=npub1xyz...  # Your public key
-   NSEC=nsec1abc...  # Your private key (keep secret!)
-   NAME=Lightning AI Gateway
-   DESCRIPTION=Fast and reliable AI API with Bitcoin payments
-   HTTP_URL=https://api.lightning-ai.com
-   ONION_URL=http://lightningai.onion
-   ```
-
-### Publishing to Nostr
-
-Routstr automatically publishes provider information to configured relays:
-
-```python
-# Published event structure (NIP-89)
-{
-    "kind": 31990,  # Application handler event
-    "pubkey": "your_public_key",
-    "content": {
-        "name": "Lightning AI Gateway",
-        "description": "Fast and reliable AI API",
-        "endpoints": {
-            "http": "https://api.lightning-ai.com",
-            "onion": "http://lightningai.onion"
-        },
-        "models": ["gpt-3.5-turbo", "gpt-4", "claude-3"],
-        "pricing": {
-            "gpt-3.5-turbo": {
-                "prompt_sats_per_1k": 3,
-                "completion_sats_per_1k": 4
-            }
-        },
-        "cashu_mints": [
-            "https://mint.minibits.cash/Bitcoin"
-        ]
-    },
-    "tags": [
-        ["d", "routstr"],
-        ["t", "ai-api"],
-        ["t", "bitcoin"],
-        ["p", "payment-proxy"]
-    ]
-}
-```
-
-### Relay Configuration
-
-Configure which relays to publish to:
-
-```python
-# Default relays
-DEFAULT_RELAYS = [
-    "wss://relay.damus.io",
-    "wss://relay.nostr.band",
-    "wss://relay.routstr.com",
-    "wss://nos.lol"
-]
-
-# Custom relay configuration
-RELAYS=wss://relay1.com,wss://relay2.com
-```
-
-## Client Discovery
-
-### Using the Discovery Endpoint
-
-Find providers through the API:
-
-```bash
-GET /v1/providers
-
-Response:
-{
-  "providers": [
-    {
-      "name": "Lightning AI Gateway",
-      "npub": "npub1xyz...",
-      "description": "Fast and reliable AI API",
-      "endpoints": {
-        "http": "https://api.lightning-ai.com",
-        "onion": "http://lightningai.onion"
-      },
-      "models": ["gpt-3.5-turbo", "gpt-4"],
-      "pricing": {
-        "gpt-3.5-turbo": {
-          "prompt_sats_per_1k": 3,
-          "completion_sats_per_1k": 4
-        }
-      },
-      "last_seen": "2024-01-01T12:00:00Z",
-      "reliability_score": 0.99
-    }
-  ]
-}
-```
-
-### Direct Nostr Queries
-
-Query Nostr relays directly:
-
-```python
-import json
-import websocket
-
-def discover_providers(relay_url: str):
-    """Discover Routstr providers from Nostr relay."""
-    ws = websocket.create_connection(relay_url)
-    
-    # Subscribe to provider events
-    subscription = {
-        "kinds": [31990],
-        "tags": {
-            "d": ["routstr"]
-        }
-    }
-    
-    ws.send(json.dumps(["REQ", "sub1", subscription]))
-    
-    providers = []
-    while True:
-        response = json.loads(ws.recv())
-        if response[0] == "EVENT":
-            event = response[2]
-            providers.append(parse_provider_event(event))
-        elif response[0] == "EOSE":  # End of stored events
-            break
-    
-    ws.close()
-    return providers
-```
-
-### JavaScript/TypeScript
-
-```typescript
-import { SimplePool } from 'nostr-tools';
-
-async function discoverProviders(): Promise<Provider[]> {
-    const pool = new SimplePool();
-    const relays = [
-        'wss://relay.damus.io',
-        'wss://relay.nostr.band'
-    ];
-    
-    const filter = {
-        kinds: [31990],
-        '#d': ['routstr']
-    };
-    
-    const events = await pool.list(relays, [filter]);
-    
-    return events.map(event => ({
-        name: event.content.name,
-        npub: nip19.npubEncode(event.pubkey),
-        url: event.content.endpoints.http,
-        models: event.content.models,
-        pricing: event.content.pricing
-    }));
-}
-```
-
-## Provider Ranking
-
-### Reliability Scoring
-
-Providers are ranked based on:
-
-```python
-class ProviderScore:
-    def calculate(self, provider: Provider) -> float:
-        score = 1.0
-        
-        # Uptime (based on recent checks)
-        uptime_ratio = provider.successful_pings / provider.total_pings
-        score *= uptime_ratio
-        
-        # Response time
-        if provider.avg_response_time < 500:  # ms
-            score *= 1.0
-        elif provider.avg_response_time < 1000:
-            score *= 0.9
-        else:
-            score *= 0.7
-        
-        # Model availability
-        model_score = len(provider.models) / 10  # Max 10 models
-        score *= min(1.0, 0.5 + model_score * 0.5)
-        
-        # Price competitiveness
-        if provider.is_cheapest_for_any_model():
-            score *= 1.1
-        
-        return min(1.0, score)
-```
-
-### Provider Selection
-
-Choose optimal provider:
-
-```python
-def select_provider(
-    providers: list[Provider],
-    model: str,
-    requirements: dict
-) -> Provider:
-    """Select best provider for requirements."""
-    
-    # Filter by model availability
-    candidates = [p for p in providers if model in p.models]
-    
-    # Filter by requirements
-    if requirements.get('tor_required'):
-        candidates = [p for p in candidates if p.onion_url]
-    
-    if requirements.get('max_price_per_1k'):
-        max_price = requirements['max_price_per_1k']
-        candidates = [
-            p for p in candidates
-            if p.pricing[model]['prompt_sats_per_1k'] <= max_price
-        ]
-    
-    # Sort by score
-    candidates.sort(key=lambda p: p.reliability_score, reverse=True)
-    
-    return candidates[0] if candidates else None
-```
-
-## Publishing Updates
-
-### Automatic Updates
-
-Routstr publishes updates when:
-
-- Node starts up
-- Configuration changes
-- Models are added/removed
-- Pricing updates
-
-### Manual Publishing
-
-Force publish current state:
-
-```python
-async def publish_provider_info():
-    """Manually publish provider information."""
-    event = create_provider_event(
-        name=os.getenv("NAME"),
-        description=os.getenv("DESCRIPTION"),
-        models=get_available_models(),
-        pricing=get_current_pricing()
-    )
-    
-    await publish_to_relays(event, RELAYS)
-```
-
-### Event Lifecycle
-
-```python
-# Publish every 6 hours
-@periodic_task(hours=6)
-async def update_nostr_presence():
-    """Keep provider information fresh."""
-    try:
-        await publish_provider_info()
-        logger.info("Updated Nostr presence")
-    except Exception as e:
-        logger.error(f"Failed to update Nostr: {e}")
-
-# Delete on shutdown
-async def remove_nostr_presence():
-    """Remove provider from discovery."""
-    deletion_event = create_deletion_event()
-    await publish_to_relays(deletion_event, RELAYS)
-```
-
-## Security Considerations
-
-### Key Management
-
-1. **Secure Storage**
-
-   ```python
-   # Never log private keys
-   SENSITIVE_VARS = ['NSEC', 'ADMIN_PASSWORD']
-   
-   def sanitize_env(env_dict: dict) -> dict:
-       return {
-           k: '***' if k in SENSITIVE_VARS else v
-           for k, v in env_dict.items()
-       }
-   ```
-
-2. **Key Rotation**
-
-   ```bash
-   # Generate new keys
-   nostril --generate-keypair
-   
-   # Update configuration
-   # Publish transition event
-   # Update all references
-   ```
-
-### Event Validation
-
-Verify provider events:
-
-```python
-def validate_provider_event(event: dict) -> bool:
-    """Validate provider announcement."""
-    # Check signature
-    if not verify_signature(event):
-        return False
-    
-    # Check required fields
-    required = ['name', 'endpoints', 'models', 'pricing']
-    content = json.loads(event['content'])
-    if not all(field in content for field in required):
-        return False
-    
-    # Verify endpoints are reachable
-    if not await check_endpoints(content['endpoints']):
-        return False
-    
-    return True
-```
-
-### Relay Security
-
-Choose relays carefully:
-
-```python
-TRUSTED_RELAYS = {
-    'wss://relay.damus.io': {
-        'operator': 'Damus',
-        'reputation': 'high',
-        'filters_spam': True
-    },
-    'wss://relay.nostr.band': {
-        'operator': 'Nostr.Band',
-        'reputation': 'high',
-        'paid_tier': True
-    }
-}
-```
-
-## Advanced Features
-
-### Multi-Relay Broadcasting
-
-Ensure wide distribution:
-
-```python
-async def broadcast_to_relays(event: dict, relays: list[str]):
-    """Broadcast event to multiple relays."""
-    tasks = []
-    for relay in relays:
-        task = asyncio.create_task(
-            publish_to_relay(event, relay)
-        )
-        tasks.append(task)
-    
-    results = await asyncio.gather(*tasks, return_exceptions=True)
-    
-    successful = sum(1 for r in results if not isinstance(r, Exception))
-    logger.info(f"Published to {successful}/{len(relays)} relays")
-```
-
-### Provider Metadata
-
-Extended metadata in events:
-
-```json
-{
-    "kind": 31990,
-    "content": {
-        "name": "Lightning AI",
-        "description": "Enterprise AI API",
-        "metadata": {
-            "established": "2024-01-01",
-            "total_requests": 1000000,
-            "average_response_ms": 250,
-            "supported_features": [
-                "streaming",
-                "function_calling",
-                "vision",
-                "embeddings"
-            ],
-            "certifications": ["SOC2", "GDPR"],
-            "contact": {
-                "nostr": "npub1contact...",
-                "email": "support@lightning-ai.com"
-            }
-        }
-    }
-}
-```
-
-### Discovery Filters
-
-Advanced filtering options:
-
-```python
-# Find providers with specific features
-GET /v1/providers?features=streaming,vision&max_price=5&min_reliability=0.95
-
-# Response includes filtered results
-{
-    "providers": [...],
-    "filters_applied": {
-        "features": ["streaming", "vision"],
-        "max_price_sats_per_1k": 5,
-        "min_reliability": 0.95
-    },
-    "total_providers": 50,
-    "matching_providers": 12
-}
-```
-
-## Monitoring
-
-### Discovery Metrics
-
-Track discovery performance:
-
-```python
-class DiscoveryMetrics:
-    def __init__(self):
-        self.relay_health = {}
-        self.provider_count = 0
-        self.query_latency = []
-    
-    async def check_relay_health(self, relay_url: str):
-        """Monitor relay connectivity."""
-        start = time.time()
-        try:
-            await connect_to_relay(relay_url)
-            latency = time.time() - start
-            self.relay_health[relay_url] = {
-                'status': 'healthy',
-                'latency_ms': latency * 1000
-            }
-        except Exception as e:
-            self.relay_health[relay_url] = {
-                'status': 'unhealthy',
-                'error': str(e)
-            }
-```
-
-### Provider Monitoring
-
-```python
-@periodic_task(minutes=5)
-async def monitor_providers():
-    """Check provider health."""
-    providers = await discover_providers()
-    
-    for provider in providers:
-        try:
-            # Test endpoint
-            response = await test_provider_endpoint(provider.http_url)
-            
-            # Update metrics
-            await update_provider_metrics(
-                provider.npub,
-                success=response.status_code == 200,
-                response_time=response.elapsed
-            )
-        except Exception as e:
-            logger.warning(f"Provider {provider.name} check failed: {e}")
-```
-
-## Troubleshooting
-
-### No Providers Found
-
-```python
-# Debug discovery issues
-async def debug_discovery():
-    """Diagnose discovery problems."""
-    issues = []
-    
-    # Check relay connectivity
-    for relay in RELAYS:
-        if not await can_connect_to_relay(relay):
-            issues.append(f"Cannot connect to {relay}")
-    
-    # Check event publishing
-    if not await verify_own_events_visible():
-        issues.append("Own events not visible on relays")
-    
-    # Check filters
-    if len(await get_all_provider_events()) == 0:
-        issues.append("No provider events on any relay")
-    
-    return issues
-```
-
-### Relay Connection Issues
-
-```bash
-# Test relay connection
-wscat -c wss://relay.damus.io
-
-# Send subscription
-["REQ","test",{"kinds":[31990],"#d":["routstr"]}]
-```
-
-## Best Practices
-
-### For Providers
-
-1. **Consistent Identity**
-   - Use same npub across services
-   - Maintain profile metadata
-   - Verify identity on multiple platforms
-
-2. **Regular Updates**
-   - Publish status every few hours
-   - Update pricing promptly
-   - Remove stale information
-
-3. **Relay Diversity**
-   - Publish to 5+ relays
-   - Include regional relays
-   - Monitor relay health
-
-### For Clients
-
-1. **Verify Providers**
-   - Check multiple relays
-   - Verify endpoints work
-   - Monitor reliability over time
-

-# Tor Support
-
-Routstr Core includes built-in support for Tor hidden services, enabling anonymous access to your API and enhanced privacy for users.
-
-## Overview
-
-Tor support provides:
-
-- **Anonymous Access**: Hidden service (.onion) address
-- **Enhanced Privacy**: No IP address logging
-- **Censorship Resistance**: Accessible from restricted networks
-- **Optional Usage**: Regular HTTP/HTTPS access remains available
-
-## Docker Setup
-
-### Using Docker Compose
-
-The included `compose.yml` automatically sets up Tor:
-
-```yaml
-version: '3.8'
-
-services:
-  routstr:
-    build: .
-    environment:
-      - TOR_PROXY_URL=socks5://tor:9050
-    ports:
-      - 8000:8000
-
-  tor:
-    image: ghcr.io/hundehausen/tor-hidden-service:latest
-    volumes:
-      - tor-data:/var/lib/tor
-    environment:
-      - HS_ROUTER=routstr:8000:80
-    depends_on:
-      - routstr
-
-volumes:
-  tor-data:
-```
-
-Start with:
-
-```bash
-docker compose up -d
-```
-
-### Getting Your Onion Address
-
-After starting, retrieve your hidden service address:
-
-```bash
-# View Tor logs
-docker compose logs tor
-
-# Or directly from the hostname file
-docker exec tor cat /var/lib/tor/hidden_service/hostname
-```
-
-Your onion address will look like:
-
-```
-roustrjfsdgfiueghsklchg.onion
-```
-
-## Manual Tor Setup
-
-### Install Tor
-
-```bash
-# Ubuntu/Debian
-sudo apt-get install tor
-
-# macOS
-brew install tor
-
-# Start Tor
-sudo systemctl start tor
-```
-
-### Configure Hidden Service
-
-Edit `/etc/tor/torrc`:
-
-```bash
-# Hidden service configuration
-HiddenServiceDir /var/lib/tor/routstr/
-HiddenServicePort 80 127.0.0.1:8000
-
-# Optional: Restrict to v3 addresses
-HiddenServiceVersion 3
-```
-
-Restart Tor:
-
-```bash
-sudo systemctl restart tor
-```
-
-Get onion address:
-
-```bash
-sudo cat /var/lib/tor/routstr/hostname
-```
-
-## Client Configuration
-
-### Using Tor with Python
-
-```python
-import httpx
-from openai import OpenAI
-
-# Configure SOCKS proxy
-proxies = {
-    "http://": "socks5://127.0.0.1:9050",
-    "https://": "socks5://127.0.0.1:9050"
-}
-
-# Create client with Tor
-http_client = httpx.Client(proxies=proxies)
-
-client = OpenAI(
-    api_key="sk-...",
-    base_url="http://roustrjfsdgfiueghsklchg.onion/v1",
-    http_client=http_client
-)
-
-# Use normally
-response = client.chat.completions.create(
-    model="gpt-3.5-turbo",
-    messages=[{"role": "user", "content": "Hello via Tor!"}]
-)
-```
-
-### Using Tor with cURL
-
-```bash
-# Install torify
-sudo apt-get install torsocks
-
-# Make request through Tor
-torify curl http://roustrjfsdgfiueghsklchg.onion/v1/models
-
-# Or with explicit proxy
-curl --socks5 127.0.0.1:9050 http://roustrjfsdgfiueghsklchg.onion/v1/models
-```
-
-### JavaScript/Node.js
-
-```javascript
-import { SocksProxyAgent } from 'socks-proxy-agent';
-import OpenAI from 'openai';
-
-// Create SOCKS agent
-const agent = new SocksProxyAgent('socks5://127.0.0.1:9050');
-
-// Configure OpenAI client
-const openai = new OpenAI({
-    apiKey: 'sk-...',
-    baseURL: 'http://roustrjfsdgfiueghsklchg.onion/v1',
-    httpAgent: agent
-});
-
-// Use normally
-const response = await openai.chat.completions.create({
-    model: 'gpt-3.5-turbo',
-    messages: [{ role: 'user', content: 'Hello via Tor!' }]
-});
-```
-
-## Configuration
-
-### Environment Variables
-
-Configure Tor proxy for outgoing connections:
-
-```bash
-# .env
-TOR_PROXY_URL=socks5://tor:9050  # Docker
-# or
-TOR_PROXY_URL=socks5://127.0.0.1:9050  # Local
-```
-
-### Publishing Onion Address
-
-Make your onion address discoverable:
-
-```bash
-# .env
-ONION_URL=http://roustrjfsdgfiueghsklchg.onion
-```
-
-This will be included in:
-
-- `/v1/info` endpoint
-- Nostr announcements
-- Admin dashboard
-
-## Security Considerations
-
-### Hidden Service Security
-
-1. **Keep Private Key Secure**
-
-   ```bash
-   # Backup hidden service keys
-   sudo tar -czf tor-keys-backup.tar.gz /var/lib/tor/routstr/
-   
-   # Restore to maintain same address
-   sudo tar -xzf tor-keys-backup.tar.gz -C /
-   ```
-
-2. **Access Control**
-
-   ```bash
-   # Restrict to authenticated clients
-   HiddenServiceAuthorizeClient stealth client1,client2
-   ```
-
-3. **Rate Limiting**
-
-   ```bash
-   # In torrc
-   HiddenServiceMaxStreams 100
-   HiddenServiceMaxStreamsCloseCircuit 1
-   ```
-
-### Operational Security
-
-1. **Separate Tor Instance**
-
-   ```yaml
-   # Use dedicated Tor container
-   tor:
-     image: ghcr.io/hundehausen/tor-hidden-service:latest
-     restart: always
-     networks:
-       - tor_network
-   ```
-
-2. **Monitor Tor Health**
-
-   ```python
-   async def check_tor_connection():
-       """Verify Tor connectivity."""
-       try:
-           async with httpx.AsyncClient(
-               proxies={"all://": TOR_PROXY_URL}
-           ) as client:
-               response = await client.get(
-                   "https://check.torproject.org/api/ip"
-               )
-               data = response.json()
-               return data.get("IsTor", False)
-       except Exception:
-           return False
-   ```
-
-3. **Logging Considerations**
-
-   ```python
-   # Don't log .onion addresses with IPs
-   def sanitize_logs(message: str) -> str:
-       # Remove IP addresses when .onion is present
-       if ".onion" in message:
-           message = re.sub(r'\d+\.\d+\.\d+\.\d+', '[IP]', message)
-       return message
-   ```
-
-## Performance Optimization
-
-### Connection Pooling
-
-```python
-# Reuse Tor circuits
-class TorConnectionPool:
-    def __init__(self, proxy_url: str):
-        self.proxy_url = proxy_url
-        self._clients = []
-    
-    async def get_client(self) -> httpx.AsyncClient:
-        if not self._clients:
-            client = httpx.AsyncClient(
-                proxies={"all://": self.proxy_url},
-                timeout=httpx.Timeout(30.0),
-                limits=httpx.Limits(
-                    max_keepalive_connections=5,
-                    max_connections=10
-                )
-            )
-            self._clients.append(client)
-        return self._clients[0]
-```
-
-### Circuit Management
-
-```python
-# Rotate Tor circuits periodically
-async def rotate_tor_circuit():
-    """Signal Tor to create new circuit."""
-    async with httpx.AsyncClient() as client:
-        # Tor control port (requires configuration)
-        response = await client.post(
-            "http://localhost:9051",
-            data="AUTHENTICATE\r\nSIGNAL NEWNYM\r\n"
-        )
-```
-
-### Caching Strategies
-
-```python
-# Cache responses for Tor users
-@lru_cache(maxsize=1000)
-def get_cached_response(
-    endpoint: str,
-    params_hash: str
-) -> Optional[dict]:
-    """Cache frequently accessed data."""
-    # Longer cache for Tor users due to latency
-    return cache.get(f"tor:{endpoint}:{params_hash}")
-```
-
-## Monitoring
-
-### Tor Metrics
-
-Track Tor-specific metrics:
-
-```python
-class TorMetrics:
-    def __init__(self):
-        self.tor_requests = 0
-        self.tor_errors = 0
-        self.circuit_builds = 0
-        self.average_latency = 0
-    
-    async def record_request(
-        self,
-        duration: float,
-        success: bool
-    ):
-        self.tor_requests += 1
-        if not success:
-            self.tor_errors += 1
-        
-        # Update average latency
-        self.average_latency = (
-            (self.average_latency * (self.tor_requests - 1) + duration)
-            / self.tor_requests
-        )
-```
-
-### Health Checks
-
-```python
-@router.get("/health/tor")
-async def tor_health():
-    """Check Tor service health."""
-    checks = {
-        "tor_proxy": await check_tor_proxy(),
-        "hidden_service": await check_hidden_service(),
-        "circuit_established": await check_circuit()
-    }
-    
-    status = "healthy" if all(checks.values()) else "unhealthy"
-    
-    return {
-        "status": status,
-        "checks": checks,
-        "metrics": {
-            "tor_requests_total": metrics.tor_requests,
-            "tor_error_rate": metrics.tor_errors / max(metrics.tor_requests, 1),
-            "average_latency_ms": metrics.average_latency * 1000
-        }
-    }
-```
-
-## Troubleshooting
-
-### Common Issues
-
-**Hidden Service Not Accessible**
-
-```bash
-# Check Tor logs
-docker compose logs tor
-# or
-sudo journalctl -u tor
-
-# Verify service is running
-sudo systemctl status tor
-
-# Test locally
-curl --socks5 127.0.0.1:9050 http://your-onion.onion/v1/info
-```
-
-**Slow Connection**
-
-- Tor adds 3+ hops of latency
-- Use connection pooling
-- Implement aggressive caching
-- Consider increasing timeouts
-
-**Connection Errors**
-
-```python
-# Implement Tor-specific retry logic
-async def tor_retry(func, max_retries=5):
-    for attempt in range(max_retries):
-        try:
-            return await func()
-        except httpx.ProxyError:
-            if attempt < max_retries - 1:
-                # Exponential backoff for circuit building
-                await asyncio.sleep(2 ** attempt)
-            else:
-                raise
-```
-
-### Debugging
-
-Enable Tor debug logging:
-
-```bash
-# In torrc
-Log debug file /var/log/tor/debug.log
-
-# Monitor in real-time
-tail -f /var/log/tor/debug.log
-```
-
-## Best Practices
-
-### For Operators
-
-1. **Backup Hidden Service Keys**
-   - Store securely offline
-   - Enables service recovery
-   - Maintains same .onion address
-
-2. **Monitor Tor Health**
-   - Check circuit establishment
-   - Track request latency
-   - Alert on failures
-
-3. **Separate Concerns**
-   - Run Tor in separate container
-   - Isolate from main application
-   - Use internal networks
-
-### For Users
-
-1. **Verify Onion Addresses**
-   - Check against multiple sources
-   - Bookmark verified addresses
-   - Watch for phishing
-
-2. **Handle Higher Latency**
-   - Increase client timeouts
-   - Implement retries
-   - Use connection pooling
-
-3. **Enhance Privacy**
-   - Use Tor Browser for web access
-   - Avoid mixing Tor/clearnet
-   - Don't include identifying info
-
-## Advanced Configuration
-
-### Multi-Hop Onion Services
-
-For extra security, chain multiple Tor instances:
-
-```yaml
-# compose.yml
-services:
-  tor-entry:
-    image: tor:latest
-    command: tor -f /etc/tor/torrc.entry
-    
-  tor-middle:
-    image: tor:latest
-    command: tor -f /etc/tor/torrc.middle
-    
-  tor-exit:
-    image: tor:latest
-    command: tor -f /etc/tor/torrc.exit
-```
-
-### Onion Service Authentication
-
-Require client authorization:
-
-```bash
-# Generate client auth
-openssl rand -base64 32 > client_auth_key
-
-# In torrc
-HiddenServiceDir /var/lib/tor/routstr/
-HiddenServicePort 80 127.0.0.1:8000
-HiddenServiceAuthorizeClient stealth payments
-```
-
-### Load Balancing
-
-Distribute load across multiple instances:
-
-```nginx
-# Onion service nginx config
-upstream routstr_backends {
-    server routstr1:8000;
-    server routstr2:8000;
-    server routstr3:8000;
-}
-
-server {
-    listen 80;
-    location / {
-        proxy_pass http://routstr_backends;
-    }
-}
-```

+# Using the API
+
+Routstr is **OpenAI-compatible**. Almost any AI application, SDK, or tool that supports custom endpoints will work out of the box. Just change two things:
+
+```
+BASE_URL  →  https://api.routstr.com/v1
+API_KEY   →  sk-... or cashuA...
+```
+
+**Both work as API keys:**
+- `sk-7f8e9d...` — Session key (from Lightning invoice or Cashu import)
+- `cashuA3s8j...` — Raw Cashu token (use directly from your wallet)
+
+If the app lets you set a base URL and API key, you're good to go.
+
+---
+
+## Quick Setup Examples
+
+### OpenAI SDK (Python/JS)
+
+```python
+client = OpenAI(base_url="https://api.routstr.com/v1", api_key="sk-...")  # or any provider's URL
+```
+
+### Claude Code
+
+```bash
+export ANTHROPIC_BASE_URL=https://api.routstr.com/v1
+export ANTHROPIC_AUTH_TOKEN=sk-...
+```
+
+### Any OpenAI-compatible app
+
+Look for "Custom API endpoint", "Base URL", or "OpenAI-compatible" in settings. Paste the URL and key.
+
+---
+
+## Detailed Examples
+
+### Python (Official SDK)
+
+```python
+from openai import OpenAI
+
+# 1. Initialize with Routstr URL and your funded key
+client = OpenAI(
+    base_url="https://api.routstr.com/v1",
+    api_key="sk-7f8e9d..." 
+)
+
+# 2. Call the API normally
+response = client.chat.completions.create(
+    model="gpt-4o",
+    messages=[{"role": "user", "content": "Hello!"}],
+    stream=True
+)
+
+for chunk in response:
+    if chunk.choices[0].delta.content:
+        print(chunk.choices[0].delta.content, end="")
+```
+
+### Node.js
+
+```javascript
+import OpenAI from 'openai';
+
+// You can use a session key OR a raw Cashu token directly
+const openai = new OpenAI({

+
+## Error Handling
+
+### Insufficient Balance (402 Payment Required)
+If your session runs out of funds, the API will return a `402` error.
+
+```json
+{
+  "error": {
+    "message": "Insufficient balance. Current: 1000 msat, Required: 5000 msat",
+    "type": "insufficient_balance",
+    "code": 402
+  }
+}
+```
+
+**Action**: Top up your key using the `/lightning/invoice` (topup purpose) or `/v1/balance/topup` endpoints.
+
+### Rate Limiting
+Routstr passes through rate limits from the upstream provider. Handle `429 Too Many Requests` with standard exponential backoff.
+
+---
+
+## Advanced: Tor Access
+
+If the node is running as a hidden service, use a SOCKS5 proxy (like `127.0.0.1:9050`).
+
+**Python:**
+```python
+import httpx
+from openai import OpenAI
+
+proxy_mounts = {
+    "http://": httpx.HTTPTransport(proxy="socks5://127.0.0.1:9050"),
+    "https://": httpx.HTTPTransport(proxy="socks5://127.0.0.1:9050"),
+}
+
+client = OpenAI(
+    base_url="http://verylongonionaddress.onion/v1",
+    api_key="sk-...",
+    http_client=httpx.Client(mounts=proxy_mounts),
+)

+# Introduction to Routstr
+
+Welcome to the Routstr Core User Guide. This guide will help you understand how to use Routstr to access AI APIs with Bitcoin micropayments.
+
+## What You'll Learn
+
+- How the payment system works (Cashu eCash)
+- Creating and managing API keys (Ephemeral Sessions)
+- Making API calls through Routstr
+- Using the admin dashboard
+
+## Prerequisites
+
+### 💰 Wallet
+
+Cashu ([cashu.me](https://cashu.me)) or Lightning ([Strike](https://strike.me), Cash App, etc.)
+
+### 🌐 Provider
+
+A Routstr node, e.g. `https://api.routstr.com`
+
+### 🤖 Client
+
+OpenAI SDK, Claude Code, Cursor, or any OpenAI-compatible tool
+
+---
+
+## How Routstr Works
+
+Routstr is a **Payment Proxy**. It sits between your code and the AI provider.
+
+### Traditional API vs Routstr
+
+| Traditional | Routstr |
+|---|---|
+| Credit Card Required | Bitcoin / Lightning / eCash |
+| Monthly Billing | Pay-per-request (Real-time) |
+| KYC / Account | No Account / Private |
+| Single Provider | Aggregated Providers |
+
+### Key Concepts
+
+#### 1. Cashu eCash
+
+Digital bearer tokens backed by Bitcoin. They are instant, private, and have no fees for internal transfers. Routstr uses these tokens as the "credits" for API requests.
+
+#### 2. Ephemeral Sessions (API Keys)
+
+Instead of a permanent account, you create a **Session**.
+
+- You fund a session with eCash or Lightning.
+- Routstr gives you an `api_key` (`sk-...`) representing that session.
+- You use the `api_key` until funds run out or you finish your task.
+- You can **refund** the remaining balance back to your wallet at any time.
+
+#### 3. Millisats (msats)
+
+Everything is priced in **millisatoshis**.
+
+- 1 Satoshi (sat) = 1,000 msats.
+- This allows for extremely precise pricing (e.g., 0.05 sats per prompt).
+
+---
+
+## Workflow: Zero to Intelligence
+
+### 1. Fund a Session
+
+You need an `api_key` with a balance.
+
+**Easiest: Use the Web UI**
+Visit the node's root page (e.g., [api.routstr.com](https://api.routstr.com)) or [chat.routstr.com](https://chat.routstr.com) → Settings to create a key visually with Lightning.
+
+**Option A: Lightning Invoice (CLI)**
+Generate an invoice and pay it with any Lightning wallet.
+
+```bash
+curl -X POST https://api.routstr.com/lightning/invoice \
+  -d '{"amount_sats": 1000, "purpose": "create"}'
+```
+
+*Returns an invoice (`bolt11`) and an ID. Once paid, the status endpoint returns your `api_key`.*
+
+**Option B: Cashu Token (Best for privacy & devs)**
+If you have a Cashu wallet, you can copy a token string (`cashuA...`) and use it directly.
+
+- **Direct Usage**: Use the token *as* your API key in the `Authorization` header.
+- **Import**: Or exchange it for a standard `sk-...` key:
+
+```bash
+curl "https://api.routstr.com/v1/balance/create?initial_balance_token=cashuA..."
+```
+
+*Returns your `api_key` immediately.*
+
+### 2. Configure Your Client
+
+Use the standard OpenAI SDK, just changing the `base_url` and `api_key`.
+
+```python
+from openai import OpenAI
+
+client = OpenAI(
+    base_url="https://api.routstr.com/v1",
+    api_key="sk-7f8e9d..."  # The key from Step 1
+)
+```
+
+### 3. Make Requests
+
+```python
+response = client.chat.completions.create(
+    model="gpt-4o",
+    messages=[{"role": "user", "content": "Explain quantum computing."}]
+)
+```
+
+### 4. Withdraw Change
+
+When you are done, get your change back as a Cashu token.
+
+```bash
+curl -X POST https://api.routstr.com/v1/balance/refund \
+  -H "Authorization: Bearer sk-7f8e9d..."
+```
+
+*Returns a `token` that you can paste back into Nutstash or Minibits to reclaim your funds.*
+
+---
+
+## Supported Features
+
+- **Responses**: `/v1/responses` (OpenAI Responses API)
+- **Chat Completions**: `/v1/chat/completions` (Streaming supported)
+- **Embeddings**: `/v1/embeddings`
+- **Models**: `/v1/models` (List available models and prices)

+# Payment Flow
+
+Routstr uses a **Pre-paid, Ephemeral** payment model. Pay first, use the funds, withdraw the rest. No accounts, no credit cards, no trails.
+
+```
+💰 Deposit  →  🤖 Use AI  →  💸 Withdraw Change
+```
+
+## 1. Creating a Balance (Deposit)
+
+To start making requests, you must create a "Balance" (represented by an API Key).
+
+### Method A: Lightning Network (Bolt11)
+
+**Ideal for**: Users connecting from a standard Lightning wallet (Strike, Cash App, WoS).
+
+1. **Request Invoice**:
+    `POST /lightning/invoice` with `{"amount_sats": 5000, "purpose": "create"}`.
+2. **Pay Invoice**: User scans and pays the QR code/bolt11 string.
+3. **Receive Key**: Routstr detects the payment and issues a new API Key (`sk-...`) pre-loaded with 5,000 sats (5,000,000 msats).
+
+### Method B: Cashu Token Import
+
+**Ideal for**: Private, instant access or automated agents.
+
+1. **Generate Token**: User creates a token in their local wallet (e.g., 1000 sats).
+2. **Import**: `GET /v1/balance/create?initial_balance_token=cashuA...`
+3. **Receive Key**: Routstr claims the token and issues an API Key (`sk-...`) with that balance.
+
+---
+
+## 2. Consuming Funds (Inference)
+
+Every time you make a request to `/v1/chat/completions` (or others), the cost is deducted from your balance **in real-time**.
+
+### Cost Calculation
+
+`Cost = (Input_Tokens * Price_Input) + (Output_Tokens * Price_Output) + Request_Fee`
+
+- Prices are defined per model (see `/v1/models`).
+- If you stream the response, the balance is deducted incrementally or finalized at the end of the stream.
+- If your balance hits 0 mid-stream, the connection is closed.
+
+### Headers
+
+Routstr checks the `Authorization: Bearer sk-...` header to identify which balance to charge.
+
+---
+
+## 3. Topping Up
+
+If your balance runs low, you don't need a new key. You can top up the existing one.
+
+### Via Lightning
+
+`POST /lightning/invoice` with `{"amount_sats": 1000, "purpose": "topup", "api_key": "sk-..."}`.
+*Once paid, the funds are added to your existing key.*
+
+### Via Cashu
+
+`POST /v1/balance/topup` with `{"cashu_token": "..."}` and `Authorization: Bearer sk-...`.
+
+---
+
+## 4. Refund (Withdrawal)
+
+Don't leave large balances sitting on a node—it's a hot wallet. When you're done, get your sats back.
+
+### Endpoint
+
+`POST /v1/balance/refund`
+
+**Headers**:
+`Authorization: Bearer sk-...`
+
+**Response**:
+
+```json
+{
+  "token": "cashuAeyJ0b2tlbiI6W3sibWludCI6...",
+  "msats": "450000"
+}
+```
+
+You can verify the refund was successful by checking that the API Key is now invalid or has 0 balance. Copy the `token` string and paste it into your Cashu wallet to claim the Bitcoin.
+
+---
+
+## Summary
+
+| Step | Action | Result |
+|------|--------|--------|
+| 💰 **Deposit** | Pay Lightning invoice or import Cashu | Get `sk-...` key |
+| 🤖 **Use** | Make API requests | Balance decreases |
+| 💸 **Refund** | Call `/v1/balance/refund` | Get Cashu token back |
+
+That's it. No monthly bills, no surprise charges, no data harvesting.

 ## Key Design Decisions
 
 ### 1. Async Architecture
 
-Everything is async for maximum performance:
-
-```python
-async def handle_request(request: Request) -> Response:
-    # Non-blocking database queries
-    api_key = await get_api_key(request.headers["Authorization"])
-    
-    # Concurrent operations
-    balance_check, rate_limit = await asyncio.gather(
-        check_balance(api_key),
-        check_rate_limit(api_key)
-    )
-    
-    # Stream response without blocking
-    async for chunk in proxy_request(request):
-        yield chunk
-```
+The system is async end-to-end, with background tasks for pricing refresh, provider discovery, model map refresh, and payouts.
 
 ### 2. Modular Design
 
@@ -166,82 +180,46 @@ Components are loosely coupled:
 
 ### 3. Error Handling
 
-Graceful degradation and clear error messages:
-
-```python
-class RoustrError(Exception):
-    """Base exception with structured error response"""
-    status_code: int = 500
-    error_type: str = "internal_error"
-    
-class InsufficientBalanceError(RoustrError):
-    status_code = 402
-    error_type = "insufficient_balance"
-```
+Exceptions are handled by FastAPI exception handlers to return consistent JSON responses with a request ID.
 
 ### 4. Database Migrations
 
-Using Alembic for schema management:
-
-- Auto-migrations on startup
-- Version control for schema changes
-- Rollback capability
-- Zero-downtime updates
+Alembic migrations are run on startup, and tables are created for any models not tracked by migrations.
 
 ## Security Architecture
 
 ### API Key Security
 
 - **Storage**: SHA-256 hashed keys
-- **Generation**: Cryptographically secure random
-- **Validation**: Constant-time comparison
-- **Rotation**: Support for key expiry
+- **Generation**: Cryptographically secure random (when creating new keys)
+- **Validation**: Hash lookup in DB
+- **Expiry**: Optional refund flow via `key_expiry_time` and `refund_address`
 
 ### Payment Security
 
-- **Token Validation**: Cryptographic verification
-- **Double-Spend Prevention**: Mint verification
-- **Balance Protection**: Atomic transactions
-- **Audit Trail**: All transactions logged
+- **Token Validation**: Cashu token redemption via mint
+- **Balance Protection**: Atomic updates and reserved balance tracking
+- **Audit Trail**: Structured logging of payments and adjustments
 
 ### Network Security
 
-- **HTTPS**: Enforced in production
 - **CORS**: Configurable origins
-- **Rate Limiting**: Per-key limits
 - **Input Validation**: Pydantic models
 
 ## Performance Considerations
 
 ### Caching Strategy
 
-```python
-# Model pricing cache
-@lru_cache(maxsize=100)
-def get_model_price(model_id: str) -> ModelPrice:
-    return MODELS.get(model_id)
-
-# Balance cache with TTL
-balance_cache = TTLCache(maxsize=1000, ttl=60)
-```
+Model and provider selections are cached in process memory and refreshed on a schedule.
 
 ### Database Optimization
 
-- **Connection Pooling**: Reuse connections
-- **Indexed Queries**: Key lookups are O(1)
-- **Batch Operations**: Group updates
 - **Async I/O**: Non-blocking queries
+- **Atomic Updates**: Balance reservation and finalization updates
 
 ### Streaming Responses
 
-Efficient memory usage for large responses:
-
-```python
-async def stream_response(upstream_response):
-    async for chunk in upstream_response.aiter_bytes():
-        # Process chunk without loading full response

+### Admin Dashboard (UI)
+
+The admin dashboard is a Next.js app using:
+
+- **Next.js 14** with App Router
+- **shadcn/ui** for components
+- **Tailwind CSS** for styling
+- **pnpm** for package management
+
+```bash
+# Development
+cd ui
+pnpm install
+pnpm dev          # http://localhost:3000
+
+# Build for production
+pnpm build
+```
+
+The UI is served by the FastAPI backend at `/admin/` when built. Use `make build-ui` to build and copy to the backend.

+# Fast tests only (skip slow and Docker tests)
+make test-fast
+
+# Performance tests
+make test-performance
+
+# Coverage
+make test-coverage
+```

+pytest
 
-# Run unit tests only (fast)
-make test-unit
+# Run a specific test file
+pytest tests/unit/test_wallet.py -v

 ```
 
-### Test Markers
+## Test Modes (Integration)
 
-Use markers to categorize tests:
+Integration tests support two execution modes:
 
-```python
-@pytest.mark.slow
-async def test_heavy_computation():
-    pass
+- Mock mode (default): uses in-memory mocks, no Docker required
+- Docker mode: uses real Docker services (Cashu mint, mock OpenAI, Nostr relay)
 
-@pytest.mark.requires_docker
-async def test_real_services():
-    pass
+Use the runner script for Docker mode:
 
-# Run without slow tests
-pytest -m "not slow"
+```bash
+./tests/run_integration.py
+```
+
+Or manually:
+
+```bash
+docker-compose -f compose.testing.yml up -d
+USE_LOCAL_SERVICES=1 pytest tests/integration/ -v
+docker-compose -f compose.testing.yml down -v
+```
+
+## Test Markers
+
+Markers are defined in `pyproject.toml`:
+
+- `integration`
+- `unit`
+- `slow`
+- `requires_docker`
+- `requires_real_mint`
+- `performance`
+- `asyncio`
+
+Examples:
+
+```bash
+# Skip slow tests
+pytest -m "not slow" -v
 
 # Run only integration tests
-pytest -m "integration"
+pytest -m "integration" -v
+
+# Run performance tests
+pytest -m "performance" -v
 ```
 
+## Fixtures and Utilities
+
+### Core Integration Fixtures
+
+Defined in `tests/integration/conftest.py`:
+
+- `integration_client` - Async HTTP client for the FastAPI app
+- `authenticated_client` - Client with a pre-created API key
+- `testmint_wallet` - Test wallet for generating Cashu tokens
+- `db_snapshot` - Database state snapshot/diff helper
+- `create_api_key` - Helper to create API keys for tests
+- `integration_engine`, `integration_session` - Async DB engine/session
+- `background_tasks_controller` - Control background tasks in tests

-## Test Fixtures
-
-### Common Fixtures
-
-Located in `tests/conftest.py`:
-
-```python
-@pytest.fixture
-async def test_db():
-    """Provide a clean test database"""
-    # Create in-memory SQLite database
-    engine = create_async_engine("sqlite+aiosqlite:///:memory:")
-    
-    async with engine.begin() as conn:
-        await conn.run_sync(SQLModel.metadata.create_all)
-    
-    async_session = sessionmaker(engine, class_=AsyncSession)
-    
-    async with async_session() as session:
-        yield session
-    
-    await engine.dispose()
-
-@pytest.fixture
-async def app_client(test_db):
-    """Provide test client with test database"""
-    app.dependency_overrides[get_db] = lambda: test_db
-    
-    async with AsyncClient(app=app, base_url="http://test") as client:
-        yield client
-    
-    app.dependency_overrides.clear()
-
-@pytest.fixture
-def mock_cashu_wallet(mocker):
-    """Mock Cashu wallet for testing"""
-    mock = mocker.patch("routstr.wallet.Wallet")
-    mock.return_value.redeem.return_value = 1000
-    return mock
-```
-
-### Using Fixtures
-
-```python
-async def test_with_fixtures(
-    test_db,          # Get test database
-    app_client,       # Get test HTTP client
-    mock_cashu_wallet # Get mocked wallet
-):
-    # Use fixtures in test
-    pass
-```
-
-## Mocking Strategies
-
-### Mocking External Services
-
-```python
-# Mock upstream API
-@pytest.fixture
-def mock_openai(mocker):
-    mock_response = mocker.Mock()
-    mock_response.json.return_value = {
-        "choices": [{
-            "message": {"content": "Hello!"},
-            "finish_reason": "stop"
-        }],
-        "usage": {
-            "prompt_tokens": 10,
-            "completion_tokens": 20,
-            "total_tokens": 30
-        }
-    }
-    
-    mocker.patch(
-        "httpx.AsyncClient.post",
-        return_value=mock_response
-    )
-
-# Mock Cashu mint
-@pytest.fixture
-def mock_mint(mocker):
-    mint = mocker.patch("routstr.wallet.Mint")
-    mint.return_value.check_proof_state.return_value = True
-    return mint
-```
-
-### Mocking Time
-
-```python
-from freezegun import freeze_time
-
-@freeze_time("2024-01-01 12:00:00")
-async def test_time_dependent():
-    # Time is frozen during test
-    key = await create_api_key(expires_in_days=30)
-    assert key.expires_at == datetime(2024, 1, 31, 12, 0, 0)
-```
-
-## Test Patterns
-
-### Testing Async Code
-
-```python
-# Always mark async tests
+@pytest.mark.integration
 @pytest.mark.asyncio
-async def test_async_function():
-    result = await async_operation()
-    assert result == expected
-
-# Test async context managers
-async def test_async_context():
-    async with create_resource() as resource:
-        assert resource.is_active
+async def test_wallet_topup(
+    authenticated_client: AsyncClient,
+    testmint_wallet: object,
+    db_snapshot: object,
+) -> None:
+    await db_snapshot.capture()
+    token = await testmint_wallet.mint_tokens(1000)
+    response = await authenticated_client.post(
+        "/v1/wallet/topup", params={"cashu_token": token}
+    )
+    assert response.status_code == 200
+    diff = await db_snapshot.diff()
+    assert len(diff["api_keys"]["modified"]) == 1
 ```
 
-### Testing Exceptions
-
-```python
-# Test specific exception
-async def test_raises_specific_error():
-    with pytest.raises(InsufficientBalanceError) as exc_info:
-        await deduct_balance(api_key, amount=999999)
-    
-    assert "Insufficient balance" in str(exc_info.value)
-    assert exc_info.value.status_code == 402
-
-# Test exception details
-async def test_exception_details():
-    with pytest.raises(RoustrError) as exc_info:
-        await risky_operation()
-    
-    error = exc_info.value
-    assert error.error_type == "validation_error"
-    assert error.detail == "Invalid input"
-```
-
-### Testing Streaming Responses
-
-```python
-async def test_streaming_response():
-    """Test streaming chat completion"""
-    chunks = []
-    
-    async with app_client.stream(
-        "POST",
-        "/v1/chat/completions",
-        json={"model": "gpt-3.5-turbo", "stream": True}
-    ) as response:
-        async for line in response.aiter_lines():
-            if line.startswith("data: "):
-                chunks.append(json.loads(line[6:]))
-    
-    # Verify chunks
-    assert len(chunks) > 0
-    assert chunks[-1] == "[DONE]"
-```
-
-### Database Testing
-
-```python
-async def test_database_transaction(test_db):
-    """Test atomic transactions"""
-    async with test_db.begin():
-        # Create test data
-        api_key = APIKey(key_hash="test", balance=1000)
-        test_db.add(api_key)
-        await test_db.flush()
-        
-        # Test rollback
-        try:
-            async with test_db.begin_nested():
-                api_key.balance = -100  # Invalid
-                await test_db.flush()
-                raise ValueError("Rollback")
-        except ValueError:
-            pass
-        
-        # Verify rollback worked
-        await test_db.refresh(api_key)
-        assert api_key.balance == 1000
-```
-

-
-```python
-@pytest.mark.benchmark
-def test_performance(benchmark):
-    """Benchmark critical functions"""
-    result = benchmark(expensive_function, arg1, arg2)

-
-1. ✅ Write tests first (TDD)
-2. ✅ Keep tests simple and focused
-3. ✅ Use descriptive test names
-4. ✅ Test edge cases
-5. ✅ Mock external dependencies
-6. ✅ Use fixtures for setup
-7. ✅ Assert specific values
-
-### Don'ts
-
-1. ❌ Don't test implementation details
-2. ❌ Don't use production services
-3. ❌ Don't rely on test order
-4. ❌ Don't ignore flaky tests
-5. ❌ Don't skip error cases
-6. ❌ Don't use hard-coded waits
-7. ❌ Don't commit commented tests
-
 ## Troubleshooting
 
-### Common Issues
-
-**Async Test Errors**
-
-```python
-# Wrong
-def test_async():  # Missing async
-    await function()
-
-# Right
-async def test_async():
-    await function()
-```
-
-**Database State**
-
-```python
-# Ensure clean state
-@pytest.fixture(autouse=True)
-async def cleanup(test_db):
-    yield
-    # Cleanup after each test
-    await test_db.execute("DELETE FROM apikey")
-    await test_db.commit()
-```
-
-**Mock Not Working**
-
-```python
-# Check import path
-mocker.patch("routstr.wallet.Wallet")  # Full path
-# Not just "Wallet"
-```
+- Docker mode failures: check `docker ps` and `docker-compose -f compose.testing.yml logs`
+- Connection errors: make sure ports 3338, 3000, 8000, and 8088 are free
+- Slow tests: use `pytest -m "not slow"` or `make test-fast`

-## Pricing
-
-- Default: pricing comes from your `models.json`.
-- Force fixed per-request pricing: set `FIXED_PRICING=true` and `FIXED_COST_PER_REQUEST`.
-- Optional token overrides when using model pricing: set
-  `FIXED_PER_1K_INPUT_TOKENS` and/or `FIXED_PER_1K_OUTPUT_TOKENS`.
-- Legacy envs are still accepted and mapped automatically:
-  `MODEL_BASED_PRICING` → `!FIXED_PRICING`, `COST_PER_REQUEST` → `FIXED_COST_PER_REQUEST`,
-  `COST_PER_1K_*` → `FIXED_PER_1K_*`.
-
-Example fixed pricing:
-
-```bash
-FIXED_PRICING=true
-FIXED_COST_PER_REQUEST=10
-```
-
-## Custom Models Configuration
-
-Create a `models.json` file:
-
-```json
-{
-  "models": [
-    {
-      "id": "gpt-4",
-      "name": "GPT-4",
-      "pricing": {
-        "prompt": "0.00003",

-## Security Best Practices
-
-### Admin Password
-
-Generate a strong password:
-
-```bash
-openssl rand -base64 32
-```
-
-### API Keys
-
-- Rotate upstream API keys regularly
-- Use read-only keys when possible
-- Monitor key usage
-
-### Network Security
-
-- Restrict CORS origins in production
-- Use HTTPS for public endpoints
-- Enable Tor for anonymity
-
-### Database Security
-
-- Regular backups
-- Encrypted storage volumes
-- Restricted file permissions
-
-## Troubleshooting
-
-### Check Current Configuration
-
-```bash
-# View all environment variables
-docker exec routstr env | sort
-
-# Test configuration
-curl http://localhost:8000/v1/info
-```
-
-### Common Issues
-
-**Missing Upstream URL**
-
-```
-ERROR: UPSTREAM_BASE_URL not set
-Solution: Set UPSTREAM_BASE_URL in .env
-```
-
-**Invalid Cashu Mint**
-
-```
-ERROR: Failed to connect to mint
-Solution: Verify CASHU_MINTS URLs are accessible
-```
-
-**Database Errors**
-
-```
-ERROR: Database connection failed
-Solution: Check DATABASE_URL and file permissions
-```
-
-## Advanced Configuration
-
-### Multiple Mints
-
-Configure fallback mints:
-
-```bash
-CASHU_MINTS=https://primary.mint,https://backup1.mint,https://backup2.mint
-```
-
-### Custom Database
-
-Use PostgreSQL instead of SQLite:
-
-```bash
-DATABASE_URL=postgresql+asyncpg://user:pass@localhost/routstr
-```
-
-### Proxy Settings
-
-For corporate environments:
-
-```bash
-HTTP_PROXY=http://proxy.company.com:8080

-
-```nginx
-server {
-    listen 443 ssl http2;
-    server_name api.yournode.com;
-
-    ssl_certificate /path/to/cert.pem;
-    ssl_certificate_key /path/to/key.pem;
-
-    location / {
-        proxy_pass http://localhost:8000;
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-        
-        # For streaming responses
-        proxy_buffering off;
-        proxy_cache off;
-        proxy_set_header Connection '';
-        proxy_http_version 1.1;
-        chunked_transfer_encoding off;
-    }
-}
-```
-
-#### Caddy Example
-
-```caddy
-api.yournode.com {
-    reverse_proxy localhost:8000 {
-        flush_interval -1
-    }
-}
-```
-
-## Monitoring
-
-### Log Management
-
-View logs:
-
-```bash
-# Docker
-docker logs -f routstr
-
-# Docker Compose
-docker compose logs -f routstr
-

-tail -f ./logs/routstr.log
-```
-
-### Metrics
-
-Monitor key metrics:
-
-- Request count and latency
-- Token validation success rate
-- Upstream API errors
-- Database size growth
-
-## Backup and Recovery
-
-### Database Backup
-
-```bash
-# Backup SQLite database
-docker exec routstr sqlite3 /app/data/keys.db ".backup /app/data/backup.db"
-
-# Copy backup locally
-docker cp routstr:/app/data/backup.db ./backup-$(date +%Y%m%d).db
-```
-
-### Restore from Backup
-
-```bash
-# Stop service
-docker compose down
-
-# Restore database
-docker cp ./backup.db routstr:/app/data/keys.db

-# Overview
-
-Routstr Core is a powerful payment proxy that brings Bitcoin micropayments to AI APIs. This overview will help you understand the core concepts and architecture.
-
-## Core Concepts
-
-### Payment Proxy
-
-Routstr acts as a transparent proxy between your application and OpenAI-compatible APIs. It:
-
-- Intercepts API requests
-- Validates payment tokens
-- Forwards requests to the upstream provider
-- Tracks usage and deducts costs
-- Returns responses to the client
-
-### Cashu eCash Protocol
-
-[Cashu](https://cashu.space) is a Bitcoin eCash protocol that enables:
-
-- **Privacy**: Payments are unlinkable and untraceable
-- **Instant Settlement**: No waiting for blockchain confirmations
-- **Micropayments**: Send fractions of a satoshi
-- **Offline Capability**: Tokens can be transferred without internet
-
-### Lightning Network Integration
-
-Routstr connects to the Lightning Network through Cashu mints, enabling:
-
-- Fast Bitcoin deposits and withdrawals
-- Global payment reach
-- Low transaction fees
-- No minimum payment amounts
-
-## Architecture
-
-### System Components

-
-You'll need a Cashu token to pay for API calls. Options:
-
-- Use a [Cashu wallet](https://cashu.space) to create tokens
-- Get test tokens from a testnet mint
-- Use the example token (for testing only)
-
-### 2. Create an API Key
-
-Send your eCash token to create an API key:
-
-```bash
-curl -X POST http://localhost:8000/v1/wallet/create \
-  -H "Content-Type: application/json" \
-  -d '{
-    "cashu_token": "cashuAeyJ0b2..."
-  }'
-```
-
-Response:
-
-```json
-{
-  "api_key": "rUvK7...",
-  "balance": 10000
-}
-```
-
-### 3. Make an API Call
-
-Use your API key like a normal OpenAI key:
-
-```python
-import openai
-
-client = openai.OpenAI(
-    api_key="rUvK7...",  # Your Routstr API key
-    base_url="http://localhost:8000/v1"
-)
-
-response = client.chat.completions.create(
-    model="gpt-4o-mini",
-    messages=[{"role": "user", "content": "Hello!"}]
-)
-
-print(response.choices[0].message.content)
-```
-
-## Example Client

-# UI Configuration
-
-This guide explains how to configure the Routstr UI for different environments.
-
-## Environment Variables
-
-The UI uses Next.js environment variables to configure API endpoints and authentication.
-
-### Centralized Configuration
-
-This project uses a centralized configuration approach with a single `.env` file in the project root. This file contains both backend and frontend configuration variables.
-
-Create or update your `.env` file in the project root:
-
-```bash
-# .env (in project root)
-
-# UI Configuration (NEXT_PUBLIC_ variables are exposed to the browser)
-NEXT_PUBLIC_API_URL=http://127.0.0.1:8000
-```
-
-### Development vs Production
-
-The same `.env` file is used for both development and production. Simply change the values:
-
-**Development:**
-
-```bash
-NEXT_PUBLIC_API_URL=http://127.0.0.1:8000
-```
-
-**Production:**
-
-```bash
-NEXT_PUBLIC_API_URL=https://api.yourroutstr.com
-```
-
-## Building the UI
-
-The build process automatically reads configuration from the root `.env` file:
-
-```bash
-# From the project root
-make ui-build
-# or
-./scripts/build-ui.sh
-```
-
-The build script will automatically:
-
-- Load `NEXT_PUBLIC_*` variables from the root `.env` file
-- Use them during the Next.js build process
-- Display warnings if the `.env` file is missing

+# Overview
+
+Routstr is a decentralized protocol for **permissionless, private, and censorship-resistant AI inference**. It creates an open marketplace where anyone can sell llm-tokens and anyone can buy them using privacy-preserving micropayments.
+
+By combining **Nostr** (for censorship-resistant discovery and communication) and **Cashu** (for private, instant Bitcoin eCash payments), Routstr effectively removes the "middleman" from the AI ecosystem.
+
+## How it Works
+
+The network consists of independent **Providers** (Sellers) and **Clients** (Buyers). There is no central server, no login, and no credit card required.
+
+1. **Discovery (Nostr)**: Providers announce their availability, models (e.g., `gpt-4o`, `deepseek-r1`), and prices on the Nostr network.
+2. **Payment (Cashu)**: Clients pay providers directly using Bitcoin eCash (Cashu tokens). These payments are untraceable and settle instantly.
+3. **Inference (Proxy)**: The Provider acts as a gateway (or runs local hardware), executing the AI model and returning the result to the Client.
+
+## Who is this for?
+
+The documentation is split into two paths depending on your goal:
+
+### 🐣 I want to BUILD on Routstr (Client)
+
+You are a developer building an AI agent, a chat app, or a script, and you want access to AI models without API keys, subscriptions, or KYC.
+
+* **No Accounts**: Just get a wallet.
+* **Privacy**: Your requests are mixed with thousands of others; providers can't profile you.
+* **Choice**: Switch between hundreds of providers instantly for the best price/performance.
+
+👉 **[Go to Client Guide](client/introduction.md)**
+
+### 🦁 I want to RUN a Node (Provider)
+
+You have API credits (OpenAI, Anthropic, etc.) or GPU capacity and want to earn Bitcoin by selling AI access to the network.
+
+* **Monetize API Keys**: Connect your OpenAI/Anthropic/OpenRouter accounts and earn sats on every request.
+* **Monetize Hardware**: Run local models (via vLLM, Ollama) and sell access.
+* **Permissionless**: No approval needed. Start the container, configure via dashboard, start earning.
+
+!!! note "Coming Soon"
+    Future versions will support node-to-node routing—run a gateway without needing your own AI provider credentials.

+# Advanced Pricing
+
+Advanced pricing strategies for fine-tuned control over your revenue model.
+
+---
+
+## Default Behavior
+
+By default, Routstr:
+
+1. **Fetches costs** from your upstream provider
+2. **Applies markup** using your fee settings
+3. **Converts to sats** using real-time BTC price
+
+**Formula**: `Price = Upstream Cost × Exchange Fee × Upstream Fee`
+
+---
+
+## Strategy 1: Fixed Per-Request
+
+Charge a flat fee regardless of model or tokens used.
+
+**Configure in Dashboard** → **Settings** → **Pricing**:
+
+- Enable **Fixed Pricing**
+- Set **Fixed Cost Per Request** (in sats)
+
+**Use cases**:
+
+- Internal tools with predictable usage
+- Simple "pay once, get response" APIs
+- Subscription-like tiers
+
+---
+
+## Strategy 2: Fixed Per-Token
+
+Override dynamic pricing with global per-token rates.
+
+**Configure in Dashboard** → **Settings** → **Pricing**:
+
+| Setting | Description |
+|---------|-------------|
+| **Fixed Per 1K Input** | Sats per 1,000 prompt tokens |
+| **Fixed Per 1K Output** | Sats per 1,000 completion tokens |
+
+When set to non-zero values, these override model-specific pricing for all models.
+
+---
+
+## Strategy 3: Per-Model Custom Pricing
+
+Set specific prices for individual models, overriding both upstream cost and global fees.
+
+**Configure in Dashboard** → **Models**:
+
+1. Click on a model (e.g., `gpt-4`)
+2. Enter **Prompt Price** and **Completion Price** (USD per 1M tokens)
+3. Save
+
+**Example**: OpenAI charges $30/1M for GPT-4. Set your price to $35/1M to lock in a margin regardless of fee settings.
+
+---
+
+## Minimum Charge
+
+Prevent dust transactions and spam:
+
+| Setting | Description | Default |
+|---------|-------------|---------|
+| **Min Request Cost** | Minimum charge in msats | 1000 (1 sat) |
+
+If a request's calculated cost falls below this (e.g., very short prompts), the client pays the minimum.
+
+---
+
+## Combining Strategies
+
+Strategies apply in order of specificity:
+
+1. **Per-model override** (highest priority)
+2. **Fixed per-token rates**
+3. **Dynamic pricing with fees** (default)
+4. **Fixed per-request** (overrides all above if enabled)
+
+**Example setup**:
+
+- Dynamic pricing as default (10% markup)
+- GPT-4 locked at $35/1M (premium model)
+- Claude Haiku at 5 sats/1K tokens (budget option)
+- Minimum 1 sat per request
+
+---
+
+## Pricing for Profit
+
+### High-Volume Strategy
+
+Lower margins, more clients:
+
+- Exchange Fee: 1.002 (0.2%)
+- Upstream Fee: 1.05 (5%)
+
+### Premium Strategy
+
+Higher margins, fewer clients:
+
+- Exchange Fee: 1.01 (1%)
+- Upstream Fee: 1.25 (25%)
+
+### Mixed Strategy
+
+- Cheap models (GLM-4.7-Flash, Seed-1.6): Low margin to attract volume
+- Premium models (GPT-5-Pro, Claude-Opus): High margin for profit

+
+---
+
+## Models
+
+Manage which AI models you offer:
+
+1. Go to **Models** in the dashboard
+2. Models are auto-discovered from your upstream
+3. For each model, you can:
+   - **Enable/Disable** — hide expensive models you don't want to serve
+   - **Override pricing** — set custom per-token rates
+   - **Create aliases** — friendly names for models
+
+See [Pricing](pricing.md) for per-model pricing strategies.

+# Deployment
+
+Production deployment guide for Routstr Provider nodes.
+
+## Docker Compose (Recommended)
+
+For production, use Docker Compose with persistent storage and optional Tor support.
+
+### Basic Setup
+
+Create a `compose.yml`:
+
+```yaml
+services:
+  routstr:
+    image: ghcr.io/routstr/proxy:latest
+    container_name: routstr
+    restart: unless-stopped
+    ports:
+      - "8000:8000"
+    volumes:
+      - ./data:/app/data
+      - ./logs:/app/logs
+```
+
+Start the node:
+
+```bash
+docker compose up -d
+```
+
+Then configure everything via the [Admin Dashboard](http://localhost:8000/admin/).
+
+---
+
+## With Tor (Anonymous Access)
+
+Add Tor to serve your node as a hidden service—no port forwarding needed.
+
+```yaml
+services:
+  routstr:
+    image: ghcr.io/routstr/proxy:latest
+    container_name: routstr
+    restart: unless-stopped
+    ports:
+      - "8000:8000"
+    volumes:
+      - ./data:/app/data
+      - ./logs:/app/logs
+    environment:
+      - TOR_PROXY_URL=socks5://tor:9050
+    depends_on:
+      - tor
+
+  tor:
+    image: ghcr.io/hundehausen/tor-hidden-service:latest
+    container_name: tor
+    restart: unless-stopped
+    volumes:
+      - ./tor-data:/var/lib/tor
+    environment:
+      - HS_ROUTER=routstr:8000:80
+```
+
+After starting, find your `.onion` address:
+
+```bash
+docker exec tor cat /var/lib/tor/hidden_service/hostname
+```
+
+See [Tor Support](tor.md) for details.
+
+---
+
+## Pre-Configuration (Optional)
+
+While everything can be configured via the dashboard, you can pre-configure settings with environment variables for automated deployments.
+
+### Using Environment Variables
+
+```yaml
+services:
+  routstr:
+    image: ghcr.io/routstr/proxy:latest
+    environment:
+      # Pre-configure upstream (optional)
+      - UPSTREAM_BASE_URL=https://api.openai.com/v1
+      - UPSTREAM_API_KEY=sk-proj-...
+      
+      # Secure the dashboard (recommended)
+      - ADMIN_PASSWORD=your-secure-password
+      
+      # Node identity
+      - NAME=My Provider Node
+      - DESCRIPTION=Fast GPT-4 access via Lightning
+      
+      # Lightning withdrawals
+      - RECEIVE_LN_ADDRESS=me@walletofsatoshi.com
+    volumes:
+      - ./data:/app/data
+```
+
+### Using an .env File
+
+```yaml
+services:
+  routstr:
+    image: ghcr.io/routstr/proxy:latest
+    env_file:
+      - .env
+    volumes:
+      - ./data:/app/data
+```
+
+Example `.env`:
+
+```bash
+UPSTREAM_BASE_URL=https://api.openai.com/v1
+UPSTREAM_API_KEY=sk-proj-...
+ADMIN_PASSWORD=change-me
+NAME=My Provider Node
+RECEIVE_LN_ADDRESS=me@walletofsatoshi.com
+```
+
+See [Configuration](configuration.md) for all available options.
+
+---
+
+## Persistence
+
+Routstr stores all data in `/app/data`:
+
+| Path | Contents |
+|------|----------|
+| `keys.db` | SQLite database (settings, API keys, sessions) |
+| `.wallet/` | Cashu wallet data (your Bitcoin!) |
+
+!!! warning "Back Up Your Data"
+    The `./data` volume contains your wallet. Losing it means losing funds. Back up regularly.
+
+---
+
+## Reverse Proxy (Optional)
+
+For custom domains and SSL, use a reverse proxy like Caddy or nginx.
+
+### Caddy Example
+
+```
+api.yournode.com {
+    reverse_proxy localhost:8000
+}
+```
+
+### nginx Example
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name api.yournode.com;
+    
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+    
+    location / {
+        proxy_pass http://localhost:8000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+---
+
+## Updates
+
+Pull the latest image and restart:
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+---
+
+## Building from Source
+
+```bash
+git clone https://github.com/routstr/routstr-core.git
+cd routstr-core
+docker build -t routstr-local .

+# Discovery
+
+Routstr uses **Nostr** as a decentralized directory for service discovery. Your node announces its presence, models, and pricing on Nostr relays, allowing clients to find you without a central server.
+
+---
+
+## How It Works
+
+1. **Provider Advertisement (Kind 38421)**: Your node periodically publishes an event with its URL, models, and pricing
+2. **Client Discovery**: Clients query relays for these events to find suitable providers
+
+---
+
+## Configuration
+
+Configure discovery in **Dashboard** → **Settings** → **Nostr**.
+
+### Required Settings
+
+| Field | Description |
+|-------|-------------|
+| **Npub** | Your node's public identity (clients use this to verify your node) |
+| **Nsec** | Your node's private key (used to sign advertisements) |
+| **Relays** | Where to publish your announcements |
+
+### Default Relays
+
+If not configured, Routstr publishes to:
+
+- `wss://relay.damus.io`
+- `wss://relay.nostr.band`
+- `wss://nos.lol`
+
+---
+
+## Advertisement Format
+
+Your node publishes events like:
+
+```json
+{
+  "kind": 38421,
+  "content": {
+    "name": "My Routstr Node",
+    "description": "Fast GPT-4 access via Lightning",
+    "endpoints": {
+      "http": "https://api.mynode.com",
+      "onion": "http://xyz...onion"
+    },
+    "models": ["gpt-4", "claude-3-opus"],

+
+## Tor Integration
+
+If you're running with Tor (see [Tor Support](tor.md)), your `.onion` address is automatically included in announcements. This allows clients to connect anonymously.
+
+---
+
+## Verify Your Announcements
+
+Check if your node is broadcasting:
+
+1. Copy your `Npub`
+2. Search on [Nostr.band](https://nostr.band) or [Primal](https://primal.net)
+3. Look for Kind 38421 events
+
+---
+
+## Generating Keys
+
+If you don't have a Nostr identity:
+
+1. Use any Nostr client (e.g., [Primal](https://primal.net), [Damus](https://damus.io))
+2. Create an account
+3. Export your keys (npub and nsec)
+4. Enter them in the dashboard
+
+Or generate keys programmatically:
+
+```python
+from nostr_sdk import Keys
+
+keys = Keys.generate()
+print(f"npub: {keys.public_key().to_bech32()}")
+print(f"nsec: {keys.secret_key().to_bech32()}")
+```

+# Pricing
+
+Routstr's pricing engine lets you act as a retailer of AI compute. You pay upstream providers (OpenAI, Anthropic, etc.) at their rates and sell to clients with your markup.
+
+---
+
+## Pricing Strategies
+
+Configure these in **Dashboard** → **Settings** → **Pricing**.
+
+### Dynamic Pricing (Default)
+
+Passes through upstream costs plus your percentage markup.
+
+**Formula**: `Client Price = Upstream Cost × Exchange Fee × Upstream Fee`
+
+| Setting | Description | Default |
+|---------|-------------|---------|
+| **Exchange Fee** | Buffer for BTC price volatility | 1.005 (0.5%) |
+| **Upstream Fee** | Your profit margin | 1.10 (10%) |
+
+**Example**: GPT-4 costs $30/1M tokens from OpenAI. With default settings:
+
+- Price: $30 × 1.005 × 1.10 = $33.17/1M tokens
+- At $60k BTC: ~55,000 sats/1M tokens
+
+### Fixed Pricing
+
+Charge a flat rate per request, regardless of model or token count.
+
+| Setting | Description |
+|---------|-------------|
+| **Fixed Pricing** | Enable flat-rate mode |
+| **Fixed Cost** | Sats per request |
+
+**Best for**: Simple proxies, internal tools, or subscription-like access.
+
+---
+
+## Per-Model Pricing
+
+Override pricing for specific models in **Dashboard** → **Models**.
+
+1. Click on a model
+2. Enter custom **Prompt Price** and **Completion Price** (USD per 1M tokens)
+3. Save
+
+This overrides both the upstream cost and your global markup for that model.
+
+**Example**: Lock GPT-4 at $35/1M tokens regardless of OpenAI's actual rate or your fee settings.
+
+---
+
+## Token-Based Overrides
+
+Set global fixed rates per token (overrides dynamic pricing for all models):
+
+| Setting | Description |
+|---------|-------------|
+| **Fixed Per 1K Input** | Sats per 1,000 prompt tokens |
+| **Fixed Per 1K Output** | Sats per 1,000 completion tokens |
+
+---
+
+## Minimum Charge
+
+Prevent spam with a minimum cost per request:
+
+| Setting | Description | Default |
+|---------|-------------|---------|
+| **Min Request Cost** | Minimum charge in msats | 1000 (1 sat) |
+
+If a request's calculated cost is lower than this, the client pays the minimum instead.
+
+---
+
+## Cost Tracking
+
+Routstr tracks balances in **millisats (msats)** for precision with cheap models.
+
+- 1 sat = 1,000 msats
+- API responses include cost in msats
+- Lightning withdrawals round down to whole sats
+
+### Client Verification (RIP-05)
+
+Clients can verify charges:
+
+1. Fetch `/v1/models` for your advertised rates
+2. Calculate expected cost from token counts
+3. Compare to `x-routstr-cost` response header

+# Quick Start
+
+Start earning Bitcoin by selling AI access in under 5 minutes.
+
+## What You'll Build
+
+A **Routstr Provider Node** acts as a gateway that:
+
+1. **Connects** to upstream AI providers (OpenAI, Anthropic, OpenRouter, etc.)
+2. **Accepts** Bitcoin payments via Cashu eCash
+3. **Serves** AI requests to clients on the network
+
+You bring the API keys, Routstr handles the billing, payments, and client management.
+
+!!! tip "Future: Node-to-Node Routing"
+    In future versions, you'll be able to run a node that connects to other Routstr nodes—eliminating the need to configure upstream providers yourself. For now, you'll need your own API credentials.
+
+---
+
+## Prerequisites
+
+- [Docker](https://docs.docker.com/get-docker/) installed
+- API credentials from at least one AI provider (OpenAI, Anthropic, OpenRouter, etc.)
+
+---
+
+## 1. Start the Node
+
+```bash
+docker run -d \
+  --name routstr \
+  -p 8000:8000 \
+  -v routstr-data:/app/data \
+  ghcr.io/routstr/proxy:latest
+```
+
+Verify it's running:
+
+```bash
+curl http://localhost:8000/v1/info
+```
+
+---
+
+## 2. Configure via Dashboard
+
+Open the **Admin Dashboard** at [http://localhost:8000/admin/](http://localhost:8000/admin/).
+
+!!! note "Default Access"
+    The dashboard has no password by default. Set one immediately in Settings for production use.
+
+### Connect Your AI Providers
+
+1. Navigate to **Settings** → **Upstream**
+2. Enter your upstream URL (e.g., `https://api.openai.com/v1`)
+3. Enter your API key
+4. Save
+
+### Set Your Profit Margin
+
+1. Go to **Settings** → **Pricing**
+2. Configure your markup (default is 10%)
+3. Optionally set a fixed price per request instead
+
+### Secure the Dashboard
+
+1. Go to **Settings** → **Admin**
+2. Set a strong password
+3. Save and re-login
+
+---
+
+## 3. Start Earning
+
+Once configured, your node is live. Clients pay you in Bitcoin (via Cashu tokens) for every AI request.
+
+### Monitor Your Earnings
+
+The dashboard shows:
+
+- **Total Wallet**: All Bitcoin held by your node
+- **User Balances**: Funds belonging to active client sessions
+- **Your Balance**: Your profit (`Total - User Balances`)
+
+### Withdraw Profits
+
+1. Go to **Withdraw** in the dashboard
+2. Select amount and mint
+3. Generate a Cashu token
+4. Redeem to your Lightning wallet
+
+---
+
+## Next Steps

+# Tor Support
+
+Running Routstr as a **Tor Hidden Service** allows you to offer API access anonymously and bypass NAT/firewalls without port forwarding.
+
+## Automatic Setup (Docker)
+
+The standard `compose.yml` includes a Tor container pre-configured to serve your node.
+
+1.  **Start the stack**: `docker compose up -d`
+2.  **Wait**: Tor takes about 30 seconds to generate keys and bootstrap.
+3.  **Find your address**:
+    ```bash
+    docker exec tor cat /var/lib/tor/hidden_service/hostname
+    ```
+    Output: `v2xyz...longaddress.onion`
+
+Routstr will automatically detect this address (via the `discover_onion_url_from_tor` logic) and include it in:
+- The `/v1/info` endpoint.
+- Nostr announcements (RIP-02).
+
+## Manual Setup
+
+If you are running outside Docker or managing Tor yourself:
+
+1.  **Install Tor**: `sudo apt install tor`
+2.  **Edit `torrc`**:
+    ```
+    HiddenServiceDir /var/lib/tor/routstr/
+    HiddenServicePort 80 127.0.0.1:8000
+    ```
+3.  **Restart Tor**: `sudo systemctl restart tor`
+4.  **Get Address**: `sudo cat /var/lib/tor/routstr/hostname`
+5.  **Configure Routstr**:
+    Set `ONION_URL=http://youraddress.onion` in your `.env` file so the node knows its own address.
+
+## Client Usage
+
+Clients connecting to your `.onion` address must route traffic through SOCKS5.
+
+**Python Example:**
+```python
+import httpx
+from openai import OpenAI
+
+client = OpenAI(
+    base_url="http://youraddress.onion/v1",
+    api_key="sk-...",
+    http_client=httpx.Client(proxy="socks5://127.0.0.1:9050")
+)
+```

-# User Guide Introduction
-
-Welcome to the Routstr Core User Guide. This guide will help you understand how to use Routstr to access AI APIs with Bitcoin micropayments.
-
-## What You'll Learn
-
-- How the payment system works
-- Creating and managing API keys
-- Making API calls through Routstr
-- Using the admin dashboard
-- Managing your balance
-
-## Prerequisites
-
-Before starting, you'll need:
-
-1. **A Running Routstr Instance**
-   - Either your own deployment or access to a public node
-   - The base URL (e.g., `https://api.routstr.com/v1`)
-
-2. **A Cashu Wallet** (optional but recommended)
-   - [Nutstash](https://nutstash.app) - Web wallet
-   - [Minibits](https://www.minibits.cash) - Mobile wallet
-   - [Cashu.me](https://cashu.me) - Simple web wallet
-
-3. **An API Client**
-   - OpenAI Python/JavaScript SDK
-   - Any HTTP client (curl, Postman, etc.)
-   - Your application code
-
-## How Routstr Works
-
-### Traditional API Access
-
-```mermaid
-graph LR
-    A[Your App] --> B[OpenAI API]
-    B --> A
-```
-
-- Direct connection to provider
-- Monthly billing
-- Credit card required
-- Usage limits
-
-### With Routstr
-
-```mermaid
-graph LR
-    A[Your App] --> B[Routstr Proxy]
-    B --> C[OpenAI API]
-    C --> B
-    B --> A
-    D[Bitcoin/eCash] --> B
-```
-
-- Pay per request with Bitcoin
-- No credit card needed
-- Anonymous payments
-- Instant settlement
-
-## Key Concepts
-
-### eCash Tokens
-
-- Digital bearer tokens backed by Bitcoin
-- Can be sent like cash - whoever has the token owns it
-- Redeemable at Cashu mints for Bitcoin
-- Perfect for micropayments
-
-### API Keys
-
-- Created by depositing eCash tokens
-- Track your balance and usage
-- Can be topped up anytime
-- Optional expiry and refund address
-
-### Balance Management
-
-- Measured in millisatoshis (msats)
-- 1 Bitcoin = 100,000,000 sats = 100,000,000,000 msats
-- Deducted based on actual usage
-- Withdrawable as eCash tokens
-
-## Typical Workflow
-
-### 1. Get Bitcoin/eCash
-
-Options:
-
-- Buy Bitcoin and deposit to a Cashu mint
-- Receive eCash tokens from someone else
-- Use a testnet mint for testing
-
-### 2. Use Your eCash
-
-You have two options for using your eCash tokens with Routstr:
-
-#### Option A: Create a Persistent Wallet
-
-Create a wallet with an API key for multiple requests:
-
-```bash
-POST /v1/wallet/create
-{
-  "cashu_token": "cashuAeyJ0..."
-}
-```
-
-This returns an API key (`sk-...`) and your balance. The wallet persists between requests.
-
-#### Option B: Direct Token Usage
-
-Use your Cashu token directly as the API key:
-
-```python
-client = OpenAI(
-    api_key="cashuAeyJ0...",  # Your Cashu token directly
-    base_url="https://api.routstr.com/v1"
-)
-```
-
-Routstr automatically converts the token to access the associated wallet. Each request consumes from the token's balance.
-
-### 3. Make API Calls
-
-With either method:
-
-```python
-# Using persistent wallet API key
-client = OpenAI(
-    api_key="sk-...",
-    base_url="https://api.routstr.com/v1"
-)
-
-# Or using Cashu token directly
-client = OpenAI(
-    api_key="cashuAeyJ0...",
-    base_url="https://api.routstr.com/v1"
-)
-```
-
-### 4. Monitor Usage
-
-- Check balance: `GET /v1/wallet/balance`
-- View admin dashboard
-- Track costs per request
-
-### 5. Withdraw Funds
-
-When done, withdraw remaining balance as eCash through the admin interface.
-
-## Supported Endpoints
-
-Routstr supports all standard OpenAI endpoints:
-
-- ✅ `/v1/chat/completions` - Chat models

-
-## Cost Structure
-
-### Pricing Models
-
-1. **Fixed Cost Per Request**
-   - Simple flat fee per API call
-   - Good for uniform usage
-
-2. **Token-Based Pricing**
-   - Pay per input/output token
-   - More accurate for varied usage
-
-3. **Model-Based Pricing**
-   - Different rates per model
-   - Reflects actual provider costs
-
-### Cost Calculation
-
-```
-Total Cost = Base Fee + (Input Tokens * Input Rate) + (Output Tokens * Output Rate)
-```
-
-Fees may include:
-
-- Exchange rate markup (BTC/USD conversion)
-- Provider margin
-- Node operator fee

-# Models & Pricing
-
-Understanding how Routstr calculates costs is essential for managing your API usage efficiently. This guide explains the pricing models and how to configure them.
-
-## Pricing Models
-
-Routstr supports three pricing models:
-
-### 1. Fixed Pricing
-
-Simple per-request charging:
-
-```bash
-FIXED_PRICING=true
-FIXED_COST_PER_REQUEST=10  # 10 sats per request
-```
-
-**Best for:**
-
-- Uniform API usage
-- Simple applications
-- Predictable costs
-
-### 2. Token-Based Pricing
-
-Charge based on actual token usage:
-
-```bash
-FIXED_PRICING=false             # use model pricing
-FIXED_COST_PER_REQUEST=1        # optional base fee
-FIXED_PER_1K_INPUT_TOKENS=5     # optional override
-FIXED_PER_1K_OUTPUT_TOKENS=15   # optional override
-```
-
-**Best for:**
-
-- Varied request sizes
-- Fair usage billing
-- Cost optimization
-
-### 3. Model-Based Pricing
-
-Dynamic pricing based on model costs:
-
-```bash
-FIXED_PRICING=false
-EXCHANGE_FEE=1.005      # 0.5% exchange fee
-UPSTREAM_PROVIDER_FEE=1.05  # 5% provider fee
-```
-
-**Best for:**
-
-- Multiple models
-- Market-based pricing
-- Automatic updates
-
-## Model Configuration
-
-### Default Models
-
-Routstr includes pricing for popular models:
-
-| Model | Input ($/1K) | Output ($/1K) | Context | Notes |
-|-------|--------------|---------------|---------|-------|
-| gpt-3.5-turbo | $0.0015 | $0.002 | 16K | Fast, economical |
-| gpt-4 | $0.03 | $0.06 | 8K | Advanced reasoning |
-| gpt-4-turbo | $0.01 | $0.03 | 128K | Large context |
-| claude-3-opus | $0.015 | $0.075 | 200K | Best quality |
-| claude-3-sonnet | $0.003 | $0.015 | 200K | Balanced |
-| llama-2-70b | $0.0007 | $0.0009 | 4K | Open source |
-
-### Custom Models File
-
-Create `models.json` to override defaults:
-
-```json
-{
-  "models": [
-    {
-      "id": "gpt-4-vision",
-      "name": "GPT-4 Vision",
-      "pricing": {
-        "prompt": "0.00003",
-        "completion": "0.00006",
-        "request": "0",
-        "image": "0.00255"
-      },
-      "context_length": 128000,
-      "supports_vision": true
-    },
-    {
-      "id": "custom-model",
-      "name": "My Custom Model",
-      "pricing": {
-        "prompt": "0.001",
-        "completion": "0.002",
-        "request": "0.0001"
-      },
-      "context_length": 8192
-    }
-  ]
-}
-```
-
-### Auto-updating Models
-
-Fetch latest models from OpenRouter:
-
-```bash
-# Update models from API
-python scripts/models_meta.py
-
-# Or manually
-curl https://openrouter.ai/api/v1/models > models.json
-```
-
-## Cost Calculation
-
-### Understanding the Formula
-
-```
-Base Cost = (Input Tokens × Input Rate) + (Output Tokens × Output Rate) + Request Fee
-
-Bitcoin Price = Current BTC/USD rate (e.g., $50,000)
-Sats Cost = (Base Cost / Bitcoin Price) × 100,000,000
-
-Final Cost = Sats Cost × Exchange Fee × Provider Fee
-```
-
-### Example Calculations
-
-**Example 1: Simple Chat (gpt-3.5-turbo)**
-
-```
-Input: 50 tokens
-Output: 150 tokens
-Model rates: $0.0015/1K input, $0.002/1K output
-
-USD Cost = (50/1000 × 0.0015) + (150/1000 × 0.002)
-         = $0.000075 + $0.0003
-         = $0.000375
-
-At $50,000/BTC: 0.75 sats
-With 5.5% total fees: 0.79 sats
-```
-
-**Example 2: Large Context (gpt-4)**
-
-```
-Input: 2,000 tokens
-Output: 500 tokens
-Model rates: $0.03/1K input, $0.06/1K output
-
-USD Cost = (2000/1000 × 0.03) + (500/1000 × 0.06)
-         = $0.06 + $0.03
-         = $0.09
-
-At $50,000/BTC: 180 sats
-With 5.5% total fees: 190 sats
-```
-
-**Example 3: Image Generation (dall-e-3)**
-
-```
-Model: dall-e-3
-Size: 1024x1024
-Quality: standard
-Cost: $0.04 per image
-
-At $50,000/BTC: 80 sats
-With 5.5% fees: 84 sats
-```
-
-## Fee Structure
-
-### Exchange Fee
-
-Covers Bitcoin/USD conversion costs:
-
-```bash
-EXCHANGE_FEE=1.005  # 0.5% default
-```
-
-Factors:
-
-- Exchange rate volatility
-- Conversion costs
-- Price update frequency
-
-### Provider Fee
-
-Node operator's margin:
-
-```bash
-UPSTREAM_PROVIDER_FEE=1.05  # 5% default
-```
-
-Covers:
-
-- Infrastructure costs

-
-## Optimization Strategies
-
-### Model Selection
-
-Choose the right model for each task:
-
-| Task | Recommended Model | Why |
-|------|-------------------|-----|
-| Simple Q&A | gpt-3.5-turbo | Fast, cheap, sufficient |
-| Code generation | gpt-4 | Better reasoning |
-| Summarization | claude-3-haiku | Good balance |
-| Creative writing | claude-3-opus | Best quality |
-| Embeddings | text-embedding-3-small | Optimized for vectors |
-
-### Prompt Engineering
-
-Reduce costs with efficient prompts:
-
-```python
-# Expensive
-prompt = """
-You are an AI assistant. Your task is to help users.
-Please provide detailed, comprehensive answers.
-Now, answer this question: What is 2+2?
-"""
-
-# Economical
-prompt = "Calculate: 2+2"
-```
-
-### Caching Strategies
-
-Implement smart caching:
-
-```python
-# Cache embedding results
-@lru_cache(maxsize=1000)
-def get_embedding(text):
-    return client.embeddings.create(
-        model="text-embedding-3-small",
-        input=text
-    )
-
-# Cache common responses
-COMMON_RESPONSES = {
-    "greeting": "Hello! How can I help you?",
-    "goodbye": "Goodbye! Have a great day!"
-}
-```
-
-### Batch Processing
-
-Process multiple items efficiently:
-
-```python
-# Instead of multiple calls
-for item in items:
-    response = client.chat.completions.create(...)
-
-# Use single call with formatted prompt
-prompt = "\n".join([f"{i+1}. {item}" for i, item in enumerate(items)])
-response = client.chat.completions.create(
-    messages=[{"role": "user", "content": f"Process these items:\n{prompt}"}]
-)
-```
-
-## Custom Pricing Rules
-
-### Time-Based Pricing
-
-Implement off-peak discounts:
-
-```python
-def calculate_multiplier():
-    hour = datetime.now().hour
-    if 2 <= hour <= 6:  # 2 AM - 6 AM
-        return 0.8  # 20% discount
-    elif 18 <= hour <= 22:  # 6 PM - 10 PM
-        return 1.2  # 20% premium
-    return 1.0
-```
-
-### Model-Specific Rules
-
-Custom pricing logic:
-
-```python
-def adjust_model_price(model, base_price):
-    # Premium for latest models
-    if "turbo" in model or "latest" in model:
-        return base_price * 1.1
-    
-    # Discount for older models
-    if "legacy" in model:
-        return base_price * 0.8
-    
-    return base_price
-```
-
-## Pricing Transparency
-
-### Public Pricing Page
-
-Display current rates:
-
-```html
-<!-- Available at /pricing -->
-<table>
-  <tr>
-    <th>Model</th>
-    <th>Input (sats/1K)</th>
-    <th>Output (sats/1K)</th>
-  </tr>
-  <!-- Dynamically generated from models.json -->
-</table>
-```
-
-### Cost Estimation API
-
-Provide cost estimates:
-
-```bash

-# Payment Flow
-
-Understanding how payments work in Routstr is key to using the system effectively. This guide explains the payment process in detail.
-
-## Overview
-
-Routstr uses a pre-funded account model where:
-
-1. Users deposit eCash tokens to create an API key
-2. Each API request deducts from the balance
-3. Users can withdraw remaining balance as eCash
-
-## Creating an API Key
-
-### Step 1: Obtain eCash Token
-
-Get a Cashu token from any compatible source:
-
-**Option A: From a Cashu Wallet**
-
-```bash
-# Example: Creating a 10,000 sat token
-cashu send 10000
-```
-
-**Option B: Lightning Invoice**
-
-```bash
-# Some mints support direct Lightning deposits
-curl -X POST https://mint.example.com/v1/mint/quote/bolt11 \
-  -d '{"amount": 10000, "unit": "sat"}'
-```
-
-**Option C: Test Tokens**
-
-```bash
-# Get test tokens from testnet mints
-# Check mint documentation for faucets
-```
-
-### Step 2: Create API Key
-
-**Note: The POST /v1/wallet/create endpoint is coming soon. Currently, you can use Cashu tokens directly as API keys in the Authorization header.**
-
-Send your token to Routstr:
-
-```bash
-curl -X POST https://api.routstr.com/v1/wallet/create \
-  -H "Content-Type: application/json" \
-  -d '{
-    "cashu_token": "cashuAeyJ0b2tlbiI6W3sibWludCI6Imh0dHBzOi8vbWlu..."
-  }'
-```
-
-**Request Parameters:**
-
-- `cashu_token` (required): The eCash token to deposit
-
-**Response:**
-
-```json
-{
-  "api_key": "sk-1234567890abcdef",
-  "balance": 10000000,
-  "created_at": "2024-01-01T00:00:00Z"
-}
-```
-
-### Step 3: Verify Balance
-
-Check your key's balance:
-
-```bash
-curl -X GET https://api.routstr.com/v1/wallet/balance \
-  -H "Authorization: Bearer sk-1234567890abcdef"
-```
-
-Response:
-
-```json
-{
-  "balance": 10000000,
-  "total_deposited": 10000000,
-  "total_spent": 0,
-  "last_used": null
-}
-```
-
-## Making API Requests
-
-### Cost Calculation
-
-Costs are calculated based on:
-
-1. **Request Type**
-   - Chat completions
-   - Embeddings
-   - Image generation
-   - Audio processing
-
-2. **Token Usage**
-   - Input tokens (prompt)
-   - Output tokens (response)
-   - Model-specific rates
-
-3. **Additional Costs**
-   - Base request fee
-   - Image generation fees
-   - Audio processing time
-
-### Example: Chat Completion
-
-```python
-import openai
-
-client = openai.OpenAI(
-    api_key="sk-1234567890abcdef",
-    base_url="https://api.routstr.com/v1"
-)
-
-# Make request
-response = client.chat.completions.create(
-    model="gpt-3.5-turbo",
-    messages=[
-        {"role": "user", "content": "Hello, how are you?"}
-    ]
-)
-
-# Check usage
-print(f"Input tokens: {response.usage.prompt_tokens}")
-print(f"Output tokens: {response.usage.completion_tokens}")
-print(f"Total tokens: {response.usage.total_tokens}")
-```
-
-### Cost Breakdown
-
-For the above request:
-
-```
-Model: gpt-3.5-turbo
-Input tokens: 13
-Output tokens: 27
-Model rates: $0.0015/1K input, $0.002/1K output
-
-USD Cost = (13/1000 * 0.0015) + (27/1000 * 0.002) = $0.0000735
-BTC/USD Rate: $50,000
-BTC Cost = 0.0000735 / 50000 = 0.00000000147 BTC = 147 sats
-With fees (5%): 154 sats
-
-Final cost: 154 sats
-```
-
-## Balance Management
-
-### Monitoring Usage
-
-Track your usage in real-time:
-
-```bash
-# Get current balance
-curl -X GET https://api.routstr.com/v1/wallet/balance \
-  -H "Authorization: Bearer your-api-key"
-
-# View recent transactions (through admin dashboard)
-# Access at https://api.routstr.com/admin/
-```
-
-### Low Balance Handling
-
-When balance is insufficient:
-
-```json
-{
-  "error": {
-    "type": "insufficient_balance",
-    "message": "Insufficient balance. Current: 100 sats, Required: 154 sats",
-    "code": "payment_required"
-  }
-}
-```
-
-### Topping Up
-
-Add funds to existing key:
-
-```bash
-curl -X POST https://api.routstr.com/v1/wallet/topup \
-  -H "Authorization: Bearer your-api-key" \
-  -H "Content-Type: application/json" \
-  -d '{
-    "cashu_token": "cashuAeyJ0b2..."
-  }'
-```
-
-## Withdrawing Balance
-
-### Via Admin Dashboard
-
-1. Navigate to `/admin/`
-2. Enter admin password
-3. Find your API key
-4. Click "Withdraw"
-5. Receive eCash token
-
-### Via API (if enabled)
-
-```bash
-curl -X POST https://api.routstr.com/v1/wallet/withdraw \
-  -H "Authorization: Bearer your-api-key" \
-  -H "Content-Type: application/json" \
-  -d '{
-    "amount": 5000,
-    "mint": "https://mint.minibits.cash/Bitcoin"
-  }'
-```
-
-## Payment Security
-
-### Token Validation
-
-Routstr validates tokens by:
-
-1. Checking signature validity
-2. Verifying with the issuing mint
-3. Ensuring no double-spending
-4. Confirming sufficient value
-
-### Failed Payments
-
-Common failure reasons:
-
-- Invalid token signature
-- Already spent token
-- Untrusted mint
-- Network issues with mint
-
-### Refund Policy
-
-- Unused balance can be withdrawn anytime
-- Expired keys with balance can be refunded
-- Node operators may have additional policies
-
-## Advanced Features
-
-### Multi-Mint Support
-
-Routstr accepts tokens from multiple mints:
-
-```bash
-CASHU_MINTS=https://mint1.com,https://mint2.com,https://mint3.com
-```
-
-Benefits:
-
-- Redundancy if one mint is down
-- User choice of mints
-- Geographic distribution
-
-### Automatic Payouts
-
-Configure automatic Lightning payouts:
-
-```bash
-RECEIVE_LN_ADDRESS=satoshi@getalby.com
-```
-
-When enabled:
-
-- Balances above threshold are swept
-- Converted to Lightning payments
-- Sent to configured address
-
-### Per-Request Payments (Coming Soon)
-
-Future support for Nut-24 headers:
-
-```bash
-curl -X POST https://api.routstr.com/v1/chat/completions \
-  -H "x-cashu: cashuAeyJ0..." \
-  -H "Content-Type: application/json" \
-  -d '{...}'
-```
-
-Response includes change:
-
-```
-HTTP/1.1 200 OK
-x-cashu: cashuAeyJjaGFuZ2Ui...
-```
-

-
-embedding = response.data[0].embedding
-print(f"Embedding dimension: {len(embedding)}")
-```
-
-### Image Generation
-
-Create images with DALL-E:
-
-```python
-response = client.images.generate(
-    model="dall-e-3",
-    prompt="A futuristic city with flying cars",
-    size="1024x1024",
-    quality="standard",
-    n=1
-)
-
-image_url = response.data[0].url
-print(f"Image URL: {image_url}")
-```
-
-### Audio Transcription
-
-Convert speech to text:
-
-```python
-with open("audio.mp3", "rb") as audio_file:
-    response = client.audio.transcriptions.create(
-        model="whisper-1",
-        file=audio_file,
-        response_format="text"
-    )
-    
-print(response.text)
-```
-
-## Error Handling
-
-### Balance Errors
-
-Handle insufficient balance gracefully:
-
-```python
-try:
-    response = client.chat.completions.create(
-        model="gpt-4",
-        messages=[{"role": "user", "content": "Hello"}]
-    )
-except Exception as e:
-    if "insufficient_balance" in str(e):
-        print("Low balance! Please top up your API key.")
-        # Implement top-up logic
-    else:
-        raise
-```
-
-### Rate Limiting
-
-Implement exponential backoff:
-
-```python
-import time
-from typing import Optional
-
-def make_request_with_retry(
-    func, 
-    max_retries: int = 3,
-    initial_delay: float = 1.0
-) -> Optional[any]:
-    for attempt in range(max_retries):
-        try:
-            return func()
-        except Exception as e:
-            if "rate_limit" in str(e) and attempt < max_retries - 1:
-                delay = initial_delay * (2 ** attempt)
-                print(f"Rate limited. Waiting {delay}s...")
-                time.sleep(delay)
-            else:
-                raise
-    return None
-```
-
-### Connection Errors
-
-Handle network issues:
-
-```python
-import httpx
-
-# Configure timeout and retries
-client = OpenAI(
-    api_key="sk-...",
-    base_url="https://your-node.com/v1",
-    timeout=httpx.Timeout(60.0, connect=5.0),
-    max_retries=2
-)
-```
-
-## Advanced Features
-
-### Using Tor
-
-Route requests through Tor for privacy:
-
-```python
-import httpx
-
-# Configure Tor proxy
-proxies = {
-    "http://": "socks5://127.0.0.1:9050",
-    "https://": "socks5://127.0.0.1:9050"
-}
-
-http_client = httpx.Client(proxies=proxies)
-
-client = OpenAI(
-    api_key="sk-...",
-    base_url="http://your-onion-address.onion/v1",
-    http_client=http_client
-)
-```
-
-### Custom Headers
-
-Add custom headers if needed:
-
-```python
-import httpx
-
-class CustomClient(httpx.Client):
-    def __init__(self, *args, **kwargs):
-        super().__init__(*args, **kwargs)
-        self.headers["X-Custom-Header"] = "value"
-
-client = OpenAI(
-    api_key="sk-...",
-    base_url="https://your-node.com/v1",
-    http_client=CustomClient()
-)
-```
-
-### Azure OpenAI compatibility
-
-To use Azure OpenAI through Routstr with minimal changes:
-
-- Set `UPSTREAM_BASE_URL` to your Azure deployments URL, for example: `https://<resource>.openai.azure.com/openai/deployments/<deployment>`
-- Set `CHAT_COMPLETIONS_API_VERSION=2024-05-01-preview`
-
-When this env var is set, Routstr automatically appends `api-version=2024-05-01-preview` to all upstream `/chat/completions` requests.
-
-### Async Operations
-
-For high-performance applications:
-
-```python
-import asyncio
-from openai import AsyncOpenAI
-
-async_client = AsyncOpenAI(
-    api_key="sk-...",
-    base_url="https://your-node.com/v1"
-)
-
-async def process_messages(messages):
-    tasks = []
-    for msg in messages:
-        task = async_client.chat.completions.create(
-            model="gpt-3.5-turbo",
-            messages=[{"role": "user", "content": msg}]
-        )
-        tasks.append(task)
-    
-    responses = await asyncio.gather(*tasks)
-    return [r.choices[0].message.content for r in responses]
-
-# Run async
-messages = ["Hello", "How are you?", "What's 2+2?"]
-results = asyncio.run(process_messages(messages))
-```
-
-## Best Practices
-
-### 1. Environment Variables
-
-Never hardcode API keys:
-
-```python
-import os
-from openai import OpenAI
-
-client = OpenAI(
-    api_key=os.getenv("ROUTSTR_API_KEY"),
-    base_url=os.getenv("ROUTSTR_BASE_URL", "https://api.routstr.com/v1")
-)
-```
-
-### 2. Error Logging
-
-Implement comprehensive logging:
-
-```python
-import logging
-
-logging.basicConfig(level=logging.INFO)
-logger = logging.getLogger(__name__)
-
-try:
-    response = client.chat.completions.create(...)
-    logger.info(f"Request successful. Tokens used: {response.usage.total_tokens}")
-except Exception as e:
-    logger.error(f"API request failed: {e}")
-    raise
-```
-
-### 3. Cost Tracking
-
-Monitor your usage:
-
-```python
-class UsageTracker:
-    def __init__(self):
-        self.total_tokens = 0
-        self.total_requests = 0
-    
-    def track(self, response):
-        self.total_tokens += response.usage.total_tokens
-        self.total_requests += 1
-        
-        # Estimate cost (example rates)
-        cost_per_1k = 0.002  # $0.002 per 1K tokens
-        estimated_cost = (self.total_tokens / 1000) * cost_per_1k
-        
-        logger.info(f"Total usage: {self.total_tokens} tokens, "
-                   f"${estimated_cost:.4f} (~{estimated_cost * 50000:.0f} sats)")
-
-tracker = UsageTracker()
-response = client.chat.completions.create(...)
-tracker.track(response)
-```
-
-### 4. Caching Responses
-
-Reduce costs with intelligent caching:
-
-```python
-import hashlib
-import json
-from functools import lru_cache
-
-@lru_cache(maxsize=100)
-def cached_completion(prompt: str, model: str = "gpt-3.5-turbo"):
-    response = client.chat.completions.create(
-        model=model,
-        messages=[{"role": "user", "content": prompt}],
-        temperature=0  # Deterministic for caching
-    )
-    return response.choices[0].message.content
-
-# Repeated calls with same prompt use cache
-result1 = cached_completion("What is 2+2?")
-result2 = cached_completion("What is 2+2?")  # From cache, no API call
-```
-
-## Testing
-
-### Mock Responses
-
-For development without spending sats:
-
-```python
-class MockOpenAI:
-    class Completions:
-        def create(self, **kwargs):
-            return type('Response', (), {
-                'choices': [type('Choice', (), {
-                    'message': type('Message', (), {
-                        'content': 'Mock response'
-                    })()
-                })],
-                'usage': type('Usage', (), {
-                    'total_tokens': 10
-                })()
-            })()
-    
-    def __init__(self):
-        self.chat = type('Chat', (), {
-            'completions': self.Completions()
-        })()
-
-# Use mock in tests
-if os.getenv('TESTING'):
-    client = MockOpenAI()
-else:
-    client = OpenAI(...)
-```
-
-### Integration Tests
-
-Test your Routstr integration:
-
-```python
-def test_routstr_connection():
-    try:
-        # Test models endpoint
-        models = client.models.list()
-        assert len(models.data) > 0
-        
-        # Test simple completion
-        response = client.chat.completions.create(
-            model="gpt-3.5-turbo",
-            messages=[{"role": "user", "content": "test"}],
-            max_tokens=5
-        )
-        assert response.choices[0].message.content
-        
-        print("✅ Routstr integration working!")
-        return True
-    except Exception as e:
-        print(f"❌ Integration test failed: {e}")
-        return False
-```
-
-## Troubleshooting
-
-### Common Issues
-
-**SSL Certificate Errors**
-
-```python
-# For development only - not for production!
-import ssl
-import httpx
-
-client = OpenAI(
-    api_key="sk-...",
-    base_url="https://localhost:8000/v1",
-    http_client=httpx.Client(verify=False)
-)
-```
-
-**Timeout Issues**
-
-```python
-# Increase timeout for slow connections
-client = OpenAI(
-    api_key="sk-...",
-    base_url="https://your-node.com/v1",
-    timeout=httpx.Timeout(120.0)  # 2 minutes
-)
-```
-
-**Debugging Requests**
-
-```python
-import logging
-import httpx
-
-# Enable debug logging
-logging.basicConfig(level=logging.DEBUG)
-httpx_logger = logging.getLogger("httpx")
-httpx_logger.setLevel(logging.DEBUG)
-```
