# Rate Limits

> API request rate limits and plan usage limits.

## Rate limit

**Limit:** 100 requests per minute per IP address.
**Response when exceeded:** `429 Too Many Requests`.

```json
{
  "error": "Too many requests, please try again later."
}
```

No rate limit headers are currently exposed on the response. If you get a `429`, wait at least 60 seconds before retrying.

Exceeding a plan limit returns:

```json
{
  "error": "You have reached your document limit for this month. Please upgrade your plan.",
  "code": "LIMIT_EXCEEDED",
  "statusCode": 400
}
```
