Rate Limiting

The API does not currently implement rate limiting. For production deployments with many clients, consider adding rate limiting middleware.

Authentication

The API does not currently implement authentication. For production deployments, consider:

• Adding API key authentication
• Implementing JWT tokens
• Using reverse proxy authentication
