tasks +- **Middleware**: CORS, logging, error handling +- **Routers**: Modular endpoint organization +- **Background Tasks**: Price updates, automatic payouts + +### Authentication System + +Located in `routstr/auth.py`, handles: + +- **API Key Validation**: Hashed key storage and lookup +- **Balance Checking**: Ensures sufficient funds +- **Rate Limiting**: Optional request throttling +- **Token Redemption**: Converts eCash to balance + +### Payment Processing + +The `routstr/payment/` module manages: + +- **Cost Calculation**: Token-based or fixed pricing +- **Model Pricing**: Dynamic pricing from models.json +- **Currency Conversion**: BTC/USD rate management +- **Fee Application**: Exchange and provider fees + +### Request Proxying + +`routstr/proxy.py` handles: + +- **Request Forwarding**: Preserves headers and body +- **Response Streaming**: Efficient memory usage +- **Usage Tracking**: Counts tokens and costs +- **Error Handling**: Graceful upstream failures + +### Database Layer + +Using SQLModel in `routstr/core/db.py`: + +```python +# Core models +APIKey: + - id: Primary key + - key_hash: Hashed API key + - balance: Current balance (msats) + - created_at:

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 +``` + +### 2. Modular Design + +Components are loosely coupled: + +- **Routers**: Separate files for different endpoints +- **Dependencies**: Injected via FastAPI's DI system +- **Models**: Shared data structures +- **Services**: Business logic separated from routes + +### 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" +``` + +### 4. Database Migrations + +Using Alembic for schema management: + +- Auto-migrations on startup +- Version control for schema changes +- Rollback capability +- Zero-downtime updates + +## Security Architecture + +### API Key Security + +- **Storage**: SHA-256 hashed keys +- **Generation**: Cryptographically secure random +- **Validation**: Constant-time comparison +- **Rotation**: Support for key expiry + +### Payment Security + +- **Token Validation**: Cryptographic verification +- **Double-Spend Prevention**: Mint verification +- **Balance Protection**: Atomic transactions +- **Audit Trail**: All transactions logged + +### 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) +``` + +### Database Optimization + +- **Connection Pooling**: Reuse connections +- **Indexed Queries**: Key lookups are O(1) +- **Batch Operations**: Group updates +- **Async I/O**: Non-blocking queries + +### 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 + yield process_chunk(chunk) +``` + +## Extension Points + +### Adding New Endpoints + +1.
