Rate limits & quotas

Per-plan request quotas, per-minute limits, and the headers that report them.

API-key traffic is limited two ways: a sliding per-minute rate and a monthly request quota, both set by your plan.

See Billing & plans for what else each tier includes.

Response headers

Every API-key response self-describes your remaining headroom:

HeaderMeaning
X-RateLimit-LimitYour per-minute ceiling
X-RateLimit-RemainingRequests left in the current minute
X-Plan-Quota-MonthlyMonthly quota for your plan
X-Plan-Quota-UsedRequests consumed this month
Retry-AfterPresent on 429 — seconds to back off

429 semantics

Exceeding either limit returns 429 with Retry-After. Back off and retry; hammering through a 429 can escalate to a temporary block at the edge.

{
  "error": "rate_limited",
  "message": "Rate limit exceeded",
  "trace_id": "01J…"
}

Anonymous traffic

The /v1/public/* namespace has its own per-IP limits and aggressive edge caching; it is designed for human-scale and light-bot consumption. For sustained programmatic volume, use an API key — or the x402 agent tier, which has no rate-limit tiers at all (every call is paid).
