# API rate limits | Orion Data API v1.3

> For the complete documentation index, see [llms.txt](https://docs.oriondata.io/llms.txt)

How the Orion Data API limits request rates and what happens when the limit is exceeded.

The Orion Data API enforces a rate limit on each user. The limit depends on the plan associated with your account.

## Free tier limits

The Free tier is sized to match the historical usage of the API, so existing integrations should not need to change.

| Limit               | Value     |
| ------------------- | --------- |
| Requests per minute | 60        |
| Requests per month  | 1,000,000 |

## Higher tiers

If your integration requires a higher request rate or monthly allowance, higher-tier plans are available. To upgrade, contact <support@ewsmonitoring.com>.

## When the limit is exceeded

Requests that exceed the rate limit return a `429 Too Many Requests` response. Back off and retry after a short delay; the limit window resets continuously.

> **Tip:**
>
> If you are bulk-extracting historical data, page through results sequentially rather than in parallel to stay well within the per-minute limit. See [API pagination](https://docs.oriondata.io/api/orion-data/v1-3/guides/pagination/).
