## Rate limits

Each API key has configurable rate limits across four time windows:

| Window     | Default        |
| ---------- | -------------- |
| Per minute | Varies by plan |
| Per hour   | Varies by plan |
| Per day    | Varies by plan |
| Per month  | Varies by plan |

When a limit is exceeded the API returns `429 Too Many Requests` with a description of which window was hit.
