How enforcement works

  1. Rate limit — per-second window per key. Exceeding returns 429 RATE_LIMIT_EXCEEDED.
  2. Monthly quota — successful (2xx) requests count against the key’s monthly quota (quota:<key>:<yyyy-mm>).
  3. Credits — direct keys that exhaust included quota debit 1 credit per successful request from user_credit_balances.
  4. x402 — when quota and credits are exhausted and x402 is enabled, a 402 offer is issued.

RapidAPI

The RapidAPI-compatible surface (/rapidapi/v1) uses X-RapidAPI-Proxy-Secret, X-RapidAPI-User, and X-RapidAPI-Subscription headers, maps subscriptions to plans, and enforces the same quota rules without credits.

Usage visibility

  • GET /user/usage aggregates monthly usage per API product for the authenticated user.
  • GET /billing/credits returns balance and ledger.
  • Admin sees per-user and platform traffic in /admin/traffic and /admin/data-health.
