# Rate Limiting

The Hook API enforces two independent limits on all requests.

## Rate limit

**100 requests per second.** Requests exceeding this rate will receive a `429 Too Many Requests` response.

## Quota

**100,000 requests per day.** The quota resets every 24 hours. Once exhausted, further requests will receive a `429 Too Many Requests` response until the quota renews.

## Response headers

Each response includes headers indicating your current usage:

| Header | Description |
|  --- | --- |
| `X-RateLimit-Limit` | Maximum requests allowed per second |
| `X-RateLimit-Remaining` | Requests remaining in the current rate limit window |
| `X-RateLimit-Reset` | Unix timestamp when the current rate limit window resets |
