Rate Limits (RPS)

Rate limits protect our infrastructure and ensure fair usage. Limits are applied per API key.

  • Free: 10 requests/second
  • Plus: 50 requests/second
  • Pro: 200 requests/second
  • Enterprise: Custom

Overage Behavior

Soft Throttle (Quota Exceeded)

When you exceed your monthly quota:

  • -API calls continue at reduced priority
  • -Response times may increase by 2-5x
  • -Email notification at 80% and 100% usage

Hard 429 (Rate Limit)

When you exceed the RPS rate limit:

HTTP/1.1 429 Too Many Requests

Implement exponential backoff (1s, 2s, 4s, 8s) and retry with jitter.

Reset Times

Monthly Quota Reset

Quotas reset on the first day of each month.

1st of month, 00:00 UTC

Rate Limit Window

Rolling 1-second window
