feat(middleware): add auth, logging, and audit middleware
- Add authentication middleware with API key validation - Add request logging middleware for observability - Add audit logging middleware for admin operations - Refactor API endpoints to use centralized auth middleware - Add comprehensive unit tests for all middleware - Add API documentation and deployment guide - Update README with health endpoints and documentation links - Fix test data isolation in router tests Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# LLM Gateway API Documentation
|
||||
|
||||
## Overview
|
||||
|
||||
LLM Gateway provides a unified API for interacting with multiple LLM providers. It supports three API formats:
|
||||
|
||||
- **OpenAI-compatible Chat Completions API** (`/v1/chat/completions`)
|
||||
- **Anthropic Messages API** (`/v1/messages`)
|
||||
- **OpenAI Responses API** (`/v1/responses`)
|
||||
|
||||
## Authentication
|
||||
|
||||
All API requests require authentication using a Virtual API Key. Include your key in one of two ways:
|
||||
|
||||
### Bearer Token (Recommended)
|
||||
|
||||
```bash
|
||||
curl -X POST https://gateway.example.com/v1/chat/completions \
|
||||
-H "Authorization: Bearer sk_your_virtual_key" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"model": "gpt-4", "messages": [{"role": "user", "content": "Hello"}]}'
|
||||
```
|
||||
|
||||
### X-API-Key Header
|
||||
|
||||
```bash
|
||||
curl -X POST https://gateway.example.com/v1/chat/completions \
|
||||
-H "X-API-Key: sk_your_virtual_key" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"model": "gpt-4", "messages": [{"role": "user", "content": "Hello"}]}'

# LLM Gateway Deployment Guide
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Docker and Docker Compose
|
||||
- Python 3.11+ (for local development)
|
||||
- SQLite (included with Python)
|
||||
- API keys for LLM providers (OpenAI, Anthropic, etc.)
|
||||
|
||||
## Quick Start with Docker
|
||||
|
||||
### 1. Clone and Configure
|
||||
|
||||
```bash
|
||||
git clone <repository-url>
|
||||
cd llm-gateway
|
||||
|
||||
# Copy environment template
|
||||
cp .env.example .env
|
||||
|
||||
# Edit configuration
|
||||
vim .env
|
||||
```
|
||||
|
||||
### 2. Generate Master Key
|
||||
|
||||
```bash
|
||||
# Generate a secure master key for encrypting provider API keys
|
||||
python -c "import secrets; print(secrets.token_hex(32))"
|
||||
```
|
||||
|
||||
Add the generated key to `.env`:
|
||||
|
||||
```env
|
||||
MASTER_KEY=your_generated_master_key_here
|
||||
```
|
||||
|
||||
### 3. Start Services
|
||||
|
||||
```bash
|
||||
# Build and start
|
||||
docker-compose up -d
|
||||
|
||||
# Check logs
|
||||
docker-compose logs -f gateway
|
||||
|

## Production Deployment
|
||||
|
||||
### Docker Compose (Recommended)
|
||||
|
||||
```yaml
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||
gateway:

||||
- MASTER_KEY=${MASTER_KEY}
|
||||
- DATABASE_URL=sqlite:///data/gateway.db
|
||||
- DEBUG=false
|
||||
- LOG_LEVEL=INFO
|
||||
restart: unless-stopped
|
||||
healthcheck:
|
||||
test: ["CMD", "curl", "-f", "http://localhost:8000/health"]
|
||||
interval: 30s
|
||||
timeout: 10s
|
||||
retries: 3
|

```
|
||||
|

### Kubernetes

### Reverse Proxy (Nginx)
|
||||
|
||||
```nginx
|
||||
upstream llm_gateway {
|
||||
server 127.0.0.1:8000;
|
||||
}
|
||||
|
||||
server {
|
||||
listen 80;
|
||||
server_name gateway.example.com;
|
||||
|
||||
# Redirect to HTTPS
|
||||
return 301 https://$server_name$request_uri;
|
||||
}
|
||||
|
||||
server {
|
||||
listen 443 ssl http2;
|
||||
server_name gateway.example.com;
|
||||
|
||||
ssl_certificate /etc/nginx/ssl/cert.pem;
|
||||
ssl_certificate_key /etc/nginx/ssl/key.pem;
|
||||
|
||||
client_max_body_size 10M;
|
||||
|
||||
location / {
|
||||
proxy_pass http://llm_gateway;
|
||||
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;
|
||||
|
||||
# SSE support
|
||||
proxy_buffering off;
|
||||
proxy_cache off;
|
||||
proxy_read_timeout 300s;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Health Endpoints
|
||||
|
||||
- `GET /health` - Basic health check
|
||||
- `GET /ready` - Readiness check (database connection)
|
||||
- `GET /admin/providers/{id}/health` - Provider-specific health
|
||||
|
||||
### Metrics
|
||||
|
||||
Request logs are stored in the database and can be queried:
|
||||
|
||||
```bash
|
||||
# Get usage statistics
|
||||
curl "http://localhost:8000/admin/usage/stats?start_date=2026-05-01&end_date=2026-05-31"
|
||||
```
|
||||
|
||||
### Logging
|
||||
|
||||
Logs are written to stdout in JSON format:
|
||||
|
||||
```json
|
||||
{
|
||||
"timestamp": "2026-05-01T12:00:00Z",
|
||||
"level": "INFO",
|
||||
"message": "Request completed",
|
||||
"request_id": "abc123",
|
||||
"method": "POST",
|
||||
"path": "/v1/chat/completions",
|
||||
"status_code": 200,
|
||||
"duration_ms": 1234
|
||||
}
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **Master Key**: Store securely, never commit to version control
|
||||
2. **API Keys**: Rotate regularly, use budget limits
|
||||
3. **Network**: Use HTTPS in production, restrict admin API access
|
||||
4. **Database**: For production, consider PostgreSQL with encryption at rest
|
||||
5. **Rate Limiting**: Configure appropriate limits to prevent abuse
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Database locked errors:**
|
||||
```bash
|
||||
# SQLite has write concurrency limits
|
||||
# Consider migrating to PostgreSQL for high-traffic deployments
|
||||
```
|
||||
|
||||
**Provider health check failures:**
|
||||
```bash
|
||||
# Check provider configuration
|
||||
curl http://localhost:8000/admin/providers/{id}/health
|
||||
|
||||
# Check logs
|
||||
docker-compose logs gateway | grep -i error
|
||||
```
|
||||
|
||||
**Rate limit errors:**
|
||||
```bash
|
||||
# Check current rate limits
|
||||
curl -I http://localhost:8000/v1/chat/completions \
|
||||
-H "Authorization: Bearer your-key"
|
||||
|
||||
# Look for X-RateLimit-* headers
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
|
||||
Enable debug logging:
|
||||
|
||||
```env
|
||||
DEBUG=true
|
||||
LOG_LEVEL=DEBUG
|
||||
```
|
||||
|
||||
## Backup and Recovery
|
||||
|
||||
### Database Backup
|
||||
|
||||
```bash
|
||||
# SQLite backup
|
||||
sqlite3 data/gateway.db ".backup data/gateway_backup.db"
|
||||
|
||||
# Or simply copy the file
|
||||
cp data/gateway.db data/gateway_backup_$(date +%Y%m%d).db
|
||||
```
|
||||
|
||||
### Disaster Recovery
|
||||
|
||||
1. Stop the service: `docker-compose down`
|
||||
2. Restore database from backup
|
||||
3. Verify configuration
|
||||
4. Restart: `docker-compose up -d`
|
||||
5. Verify health: `curl http://localhost:8000/health`
