# Rate limits

> Hourly request limits per account.

Each account can make **1,000 requests per hour** by default. The limit is shared by all API keys on the account.

The window is fixed to the clock hour in UTC. The count resets at the start of each hour, for example at 14:00:00 UTC, not one hour after your first request.

Every authenticated response includes these headers, including `429` responses:

| Header                  | Meaning                              |
| ----------------------- | ------------------------------------ |
| `X-RateLimit-Limit`     | Requests allowed in the current hour |
| `X-RateLimit-Remaining` | Requests left in the current hour    |

When the limit is reached, the API returns `429 Too Many Requests` until the next hour starts. The API does not send a `Retry-After` header. Wait until the top of the next UTC hour and retry.

Requests rejected with `401 Unauthorized` do not count toward the limit.

To fetch data with fewer requests, use a larger `limit` (up to 500) on list queries. See [Pagination and sorting](/home/get-started/pagination). If you need a higher limit, contact Tradespace support.
