# Rate Limits

> How DFNS rate limits the API: what the limit is measured against, the response headers that report your usage, and where to find the request-per-minute quota for your plan.

  const url = "https://support.dfns.co";
  return <a href={url} target="_blank">{children || url}</a>;
};

DFNS caps how many API requests an organization can make per minute. This keeps the platform stable and usage fair across all organizations.

## How the limit is measured

* The limit applies **per organization**, across every application and service account it owns — not per API key or per endpoint.
* Requests are counted over a **60-second window**. Exceeding the limit returns [`429 Too Many Requests`](/api-reference/error-codes#429-too-many-requests) until the window resets.

Rate-limited responses carry headers describing your current usage:

| Header                  | Meaning                                                    |
| ----------------------- | ---------------------------------------------------------- |
| `X-RateLimit-Limit`     | Your maximum requests per minute.                          |
| `X-RateLimit-Remaining` | Requests left in the current window.                       |
| `X-RateLimit-Reset`     | Unix time (seconds) when the window resets.                |
| `Retry-After`           | On a `429`, the number of seconds to wait before retrying. |

Back off using `Retry-After` (or `X-RateLimit-Reset`) rather than retrying immediately. See [handling `429` responses](/api-reference/error-codes#429-too-many-requests) for the recommended retry strategy.

## Your quota

The request-per-minute limit depends on your plan. See [DFNS pricing](https://www.dfns.co/pricing) for the quota at each tier.
