Rate limits & quotas

Per-second rate limits

Each API key is limited per second based on its plan. Exceeding it returns 429 rate_limited with a Retry-After header.

Plan	Requests/second	Included renders/month	Overage
Free	1/s	100	Hard stop
Hobby	3/s	2,000	$0.009/render
Startup	5/s	10,000	$0.005/render
Growth	10/s	50,000	$0.003/render
Scale	20/s	200,000	$0.002/render

All three products share one pool. A screenshot, a PDF, and an OG image each cost 1 render.
Cache hits are free — they don't touch the quota.
Failed renders are not billed.
The free plan stops hard at 100 renders (402 quota_exceeded).
Paid plans run into metered overage. A spend cap (4× included renders by default) returns 429 spend_cap_reached so a runaway loop can't surprise-bill you. Raise it from the dashboard if you need more headroom.
