# Rate limiting

> Understand Kloo API rate limits and response headers.

The API allows **60 requests per 60 seconds** per API key.

## Response headers

| Header                  | Description                              |
| ----------------------- | ---------------------------------------- |
| `X-RateLimit-Limit`     | Maximum requests allowed in the window   |
| `X-RateLimit-Remaining` | Remaining requests in the current window |
| `X-RateLimit-Reset`     | When the window resets                   |

When you exceed the limit, the API returns **429** with a message asking you to wait.

<Warning>
  If you hit 429, back off and retry after the reset window. Do not hammer the API.
