Rate Limits

Rate limits ensure fair usage and service stability for all customers. When you exceed a limit, the API returns a 429 Too Many Requests error.

Request Limits

All limits are per API key, per 24-hour rolling window.

Every response includes headers to help you monitor your usage:

Header	Description
`x-ratelimit-requests-limit`	Maximum requests allowed in the time window
`x-ratelimit-requests-remaining`	Requests remaining in the current window
`x-ratelimit-requests-reset`	Seconds until the rate limit window resets
`retry-after`	Seconds to wait before retrying (0 if allowed, positive if rate limited)

HTTP/1.1 429 Too Many Requests
x-ratelimit-requests-limit: 100
x-ratelimit-requests-remaining: 0
x-ratelimit-requests-reset: 86400
retry-after: 3600

When you hit a rate limit:

3     "code": "rate_limit_exceeded",
4     "message": "You have exceeded your daily request limit for this endpoint."
5   }
