  The numbers are published in two places, including a machine-readable one — GET /api/v1/ returns
  free_tier.limits "5000/day, 60/min". What is NOT published is any runtime signal: no
  X-RateLimit-*, RateLimit-* or Retry-After header was returned on any live response, and the status
  code and body on exhaustion are undocumented. An agent can budget against the documented ceiling
  but cannot see how much of it is left, nor tell a 429 apart from any other failure without
  provoking one.

    Live headers on GET /api/v1/leagues/ (401) and GET /api/v1/ (200) on 2026-09-04 carried only
    date, content-type, cf-cache-status, cross-origin-opener-policy, referrer-policy, rndr-id,
    server, vary, x-content-type-options, x-frame-options, x-render-origin-server, cf-ray, alt-svc.
exhaustion:
  status_code: undocumented
  body: undocumented
  note: >-
    Not provoked — establishing it would require a key and deliberate abuse of a free service. The
    provider's own MCP client has no 429/backoff handling, which suggests no Retry-After contract to
    honour.
quota_scope: 'per API key (keys are self-serve and free, so quota is per key, not per organisation)'
