API REFERENCE

Rate limits & credits

One credit per successful render, a monthly allowance per plan, and per-key throttling.

Credits

Each successful render costs one credit. Failed requests (4xx errors) don't consume credits. Sign-up grants 100 free credits as a one-time bonus; after that, paid plans include a monthly allowance that refreshes each billing period. When you run out, renders return 402 payment_required until you upgrade or the period resets.

Rate limits

Requests are rate-limited per API key. If you exceed the limit you'll get429 rate_limited — back off and retry with exponential backoff. Spread bulk jobs over time rather than firing them all at once, and use a separate key per workload so one busy integration doesn't throttle the rest.
