# 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.

## Plan limits

Beyond the per-IP rate limit, your account has usage limits based on your subscription plan:

| Resource | Free | Paid | Self-hosted | Enterprise |
|---|---|---|---|---|
| Documents/month | 5 | Unlimited | Unlimited | Unlimited |
| Total recipients | 10 | Unlimited | Unlimited | Unlimited |
| Direct-link templates | 3 | Unlimited | Unlimited | Unlimited |

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
}
```

## Associated error codes

| Code | HTTP status | Description |
