# Rate limiting

> DRN API is rate limited. The limit is enforced for every , and the default rate limit per API key is **5 req/sec**.

If you exceed the rate limit when making a DRN API call, you'll get an HTTP 429 error:

```json JSON theme={"theme":"github-dark-dimmed"}
// HTTP 429
{
  "error": {
    "code": "http.too_many_requests",
    "message": "Too many requests"
  }
}
```

You can use the `Retry-After` response header to get the number of seconds after which you can retry your request.

If you need a higher limit, reach out to [drn@fingerprint.com](mailto:drn@fingerprint.com).
