# Rate and usage limits

> Understand API rate limits and usage restrictions

External API endpoints are rate limited to **120 requests per minute** and **1,500 requests per hour**. If you exceed either limit, the API will return an HTTP `429 Too Many Requests` status code.

To help you monitor your usage, each API response includes the following headers:

| Header                  | Description                                                                |
| ----------------------- | -------------------------------------------------------------------------- |
| `X-RateLimit-Limit`     | The maximum number of requests allowed per minute.                         |
| `X-RateLimit-Remaining` | The number of requests remaining in the current rate limit window.         |
| `X-RateLimit-Reset`     | The time (in UTC epoch seconds) when the current rate limit window resets. |
