Rate limits - Nowadays API

Requests are rate limited per API key. Limits are approximate and enforced on a best-effort basis.

Hitting the limit

When you exceed the limit, the API returns 429 Too Many Requests with the standard error shape:

{
  "success": false,
  "error": "Too Many Requests"
}

Handling 429

Back off and retry. Wait before retrying, and increase the delay on repeated 429s (exponential backoff).
Spread out bulk work. Paginate steadily rather than firing many concurrent requests.

If you have a legitimate need for a higher limit, contact us — limits may be raised on request.
