Rate Limits & Errors

Every key has a daily request cap, bucketed per UTC day and enforced before any other work happens on the request.

Daily request cap

New keys default to 500 requests/day. This counts every call — catalog reads, uploads, generations, and status polls all count against the same number. Need a higher cap for a production integration? Ask via Support.

429 · cap reached{ "success": false, "error": "Daily request cap (500) reached for this key." }

Polling budget

Polling GET /v1/generations/:id counts toward your daily cap like any other request. Poll every 2–3 seconds, not tighter — most jobs finish in 10–60 seconds, so even a slow-finishing job costs well under 30 requests.
