# Rate Limits

> API rate limits and availability

## Rate Limits

The AthenaHQ API enforces the following rate limits:

* **60 requests per minute** per organization
* **No limit** on total number of requests

Rate limits are enforced on a per-organization basis. All API keys within the same organization share this limit. If you exceed the rate limit, subsequent requests will be rejected until the rate limit window resets.

## Response Headers

All authenticated API responses include rate limit headers:

| Header                   | Description                                         |
| ------------------------ | --------------------------------------------------- |
| `x-rate-limit-limit`     | Maximum requests allowed per minute (60)            |
| `x-rate-limit-remaining` | Requests remaining in the current window            |
| `x-rate-limit-reset`     | Unix timestamp (seconds) when the rate limit resets |

When you exceed the rate limit (429 response), an additional header is included:

| Header        | Description                     |
| ------------- | ------------------------------- |
| `retry-after` | Seconds to wait before retrying |
