✅ Best Practices & Tips

Always replace "YOUR_API_KEY" with your actual authenticated key.
Validate input parameters before making requests to avoid errors.
Implement rate limiting on your side to prevent overwhelming the server.
For real-time applications (e.g., live tickers), consider upgrading to WebSocket connections for lower latency and continuous updates.
