## Authentication Status

Authentication is currently **DISABLED** in development mode. The following endpoints require authentication when enabled:

1. **POST** `/api/v1/pose/analyze` - Analyze pose data with custom parameters
2. **POST** `/api/v1/pose/historical` - Query historical pose data
3. **POST** `/api/v1/pose/calibrate` - Start system calibration
4. **GET** `/api/v1/pose/calibration/status` - Get calibration status
5. **POST** `/api/v1/stream/start` - Start streaming service
6. **POST** `/api/v1/stream/stop` - Stop streaming service
7. **GET** `/api/v1/stream/clients` - List connected clients
8. **DELETE** `/api/v1/stream/clients/{client_id}` - Disconnect specific client
9. **POST** `/api/v1/stream/broadcast` - Broadcast message to clients

## Rate Limiting Status

Rate limiting is currently **DISABLED** in development mode. When enabled:

- Anonymous users: 100 requests/hour
- Authenticated users: 1000 requests/hour
- Admin users: 10000 requests/hour

Path-specific limits:
- `/api/v1/pose/current`: 60 requests/minute
- `/api/v1/pose/analyze`: 10 requests/minute
- `/api/v1/pose/calibrate`: 1 request/5 minutes
- `/api/v1/stream/start`: 5 requests/minute
- `/api/v1/stream/stop`: 5 requests/minute

## Error Response Format

All error responses follow a consistent format:

```json
{
  "error": {
    "code": 404,
    "message": "Endpoint not found",
    "type": "http_error"
  }
}
```

Validation errors include additional details:

```json
{
  "error": {
    "code": 422,
    "message": "Validation error",
    "type": "validation_error",
    "details": [...]
  }
}
```

## WebSocket Message Format

### Connection Establishment
```json
{
  "type": "connection_established",
  "client_id": "unique-client-id",
  "timestamp": "2025-06-09T16:00:00.000Z",
  "config": {
    "zone_ids": ["zone_1"],
    "min_confidence": 0.5,
    "max_fps": 30
  }
}
```

### Pose Data Stream
```json
{
  "type": "pose_update",
  "timestamp": "2025-06-09T16:00:00.000Z",
  "frame_id": "frame-123",
  "persons": [...],
  "zone_summary": {...}
}
```

### Error Messages
```json
{
  "type": "error",
  "message": "Error description"
}
```

## Performance Metrics

- **Average Response Time**: ~2.5ms (excluding health check)
- **Health Check Time**: ~1015ms (includes system metrics collection)
- **WebSocket Connection Time**: ~9ms average
- **OpenAPI Schema Generation**: ~14.6ms

## Known Issues

1. **CSI Processing**: Initial implementation had method name mismatch (`add_data` vs `add_to_history`)
2. **Phase Sanitizer**: Required configuration parameters were missing
3. **Stream Service**: Missing `shutdown` method implementation
4. **WebSocket Paths**: Documentation showed incorrect paths (`/ws/pose` instead of `/api/v1/stream/pose`)

## Recommendations

### For Development

1. Keep authentication and rate limiting disabled for easier testing
2. Use mock data for hardware and pose estimation
3. Enable all documentation endpoints
4. Use verbose logging for debugging

### For Production

1. **Enable Authentication**: Set `ENABLE_AUTHENTICATION=true`
2. **Enable Rate Limiting**: Set `ENABLE_RATE_LIMITING=true`
3. **Disable Mock Data**: Set `MOCK_HARDWARE=false` and `MOCK_POSE_DATA=false`
4. **Secure Endpoints**: Disable documentation endpoints in production
5. **Configure CORS**: Restrict `CORS_ORIGINS` to specific domains
6. **Set Secret Key**: Use a strong, unique `SECRET_KEY`
7. **Database**: Use PostgreSQL instead of SQLite
8. **Redis**: Enable Redis for caching and rate limiting
9. **HTTPS**: Use HTTPS in production with proper certificates
10. **Monitoring**: Enable metrics and health monitoring

## Test Script Usage

To run the API tests:

```bash
python scripts/test_api_endpoints.py
```

Test results are saved to: `scripts/api_test_results_[timestamp].json`

## Conclusion

The WiFi-DensePose API is functioning correctly in development mode with:
- ✅ All public endpoints working
- ✅ WebSocket connections established successfully  
- ✅ Proper error handling and response formats
- ✅ Mock data generation for testing
- ❌ Protected endpoints correctly requiring authentication (when enabled)

The system is ready for development and testing. For production deployment, follow the recommendations above to enable security features and use real hardware/model implementations.
