# Rate limits

> Default request-rate ceilings for v1 API keys and how to request an increase.

<Warning>
  **v1 sunsets December 31, 2026.** Migrate to v2 — see the [migration guide](/v1/migration-v1-to-v2).
</Warning>

All API keys are allowed up to **30 requests per second** across all combined endpoints by default. If a higher limit is required, reach out to [support@openfx.com](mailto:support@openfx.com).

## Example response headers

Each response includes headers describing the current rate-limit state for the key:

```http theme={null}
HTTP/1.1 200 OK
X-RateLimit-Limit: 30
X-RateLimit-Remaining: 28
X-RateLimit-Reset: 1
```

When the limit is exceeded the API returns `429 Too Many Requests`.
