Rate Limits

Rate limits are enforced per API key, with an additional global per-IP ceiling applied before authentication.

Tiers

Tier	Requests / minute	Burst / second	Max concurrent jobs	Auto-upgrade at
Free	20	3	2	$0 default
Tier 1	100	10	10	At least $10 total spend
Tier 2	500	25	50	At least $50 total spend
Tier 3	2,000	50	200	At least $250 total spend
Enterprise	5,000	100	500	Contact support

The Free tier also has a 1,000 requests/day cap. Paid tiers have no daily cap.

Handling 429 responses

When you exceed a limit, the API returns 429 Too Many Requests.

HTTP/1.1 429 Too Many Requests
retry-after: 12
x-ratelimit-limit-requests: 100
x-ratelimit-remaining-requests: 0
x-ratelimit-reset-requests: 2026-05-09T10:31:00Z

Wait the number of seconds in retry-after before retrying. Clients should use exponential backoff with jitter.

Failure policy

If rate-limiting infrastructure is temporarily unavailable, requests are allowed through. Limits resume automatically when infrastructure recovers.
