description: >-
  Genome publishes NO rate limits. This file replaces a 2026-05-04 bulk-sweep scaffold that invented
  free/professional/enterprise tiers at 10/100/1000 requests per minute and an X-RateLimit-* header
  set — none of which Genome documents or returns. limit_count is 0 because an honest zero is the
  measurement.

  result: no throttling policy, no quota and no limit of any kind is stated on any page.

  probe_url: https://api.genome.eu/api/pf/host-to-host
  probe_method: POST
  probe_result: >-
    HTTP 200. Response headers were date, content-type, content-length, server, x-itc-executiontype,
    x-itc-rayid, x-itc-api, x-itc-code, cache-control and pragma. No X-RateLimit-*, no RateLimit-*, no
    Retry-After.
responseCodes:
  throttled: null
  note: >-
    No 429 is documented and the API does not use HTTP status codes for application outcomes anyway.
    The response-code registry contains no throttling code; the closest adjacent controls are 2007
    (amount below or above restrictions), 3126 (withdrawal frequency limit exceeded, an issuer-side
    control) and 3202 (volume limit exceeded, an anti-fraud control) — none of them is an API rate limit.
adjacent_controls:
- code: 2008
  name: Access from this IP-address is not available
  note: >-
    A source-IP allowlist gates the merchant-platform endpoints. Observed live on 2026-09-12 against
    https://api.genome.eu/api/mp/payout. This is access control, not rate limiting.
- code: 3202
  name: Volume limit exceeded
  note: Anti-fraud volume control on payments, not on API calls.
- code: 3126
  name: Withdrawal frequency limit exceeded
  note: Issuer-side control surfaced through the decline band.
consumer_impact: >-
  With no published limit and no runtime signal, a client has nothing to back off against. An
  autonomous caller cannot distinguish "slow down" from "broken", and the only safe strategy is a
  conservative self-imposed ceiling plus the CHECK-on-unknown rule in
  conventions/genome-conventions.yml.
