429 Too Many Requests

What causes this error

Your application exceeded the API's rate limit. This protects the server from being overwhelmed. The Retry-After header indicates how long to wait before making another request.

How to fix it

Implement exponential backoff and respect the Retry-After header. Reduce request frequency, batch requests where possible, or cache responses. Consider upgrading your API plan for higher limits.

// Implement exponential backoff
await new Promise(r => setTimeout(r, retryAfter * 1000));
