Rate Limits

API rate limits are enforced based on the tier associated with your API key. Limits are tracked on two dimensions: requests per second and requests per month. Only successful responses (where success is true) count toward your monthly quota.

Current usage is returned in every API response via the following headers:

Response HeadersX-RateLimit-Limit-Second: 10X-RateLimit-Remaining-Second: 9X-RateLimit-Limit-Month: 1000X-RateLimit-Remaining-Month: 842

If you exceed a rate limit, the API returns a 429 status with a Retry-After header indicating when you can resume.
