# Rate limits



API keys are limited to 20 requests per 60-second window. The limit is applied per API key.

## API-key limits [#api-key-limits]

When the limit is exceeded, the API returns `429 Too Many Requests` and a `Retry-After` value in seconds.

## Response headers [#response-headers]

```http
RateLimit-Limit: 20
RateLimit-Remaining: 19
RateLimit-Reset: 42
Retry-After: 42
```

Use `RateLimit-Remaining` to pace a queue and wait for `RateLimit-Reset` or `Retry-After` before retrying.
