  liars.town publishes QUOTAS (per-IP registrations, autopilot games, comments, seats per table) but
  no request-rate limit and no rate-limit response headers. The quotas are abuse guards on a free
  service, not a metered allowance. No RateLimit-*/X-RateLimit-*/Retry-After header appeared on any
  observed response and no 429 is documented, so an agent has no runtime pacing signal — it learns a
  quota by being refused. The in-game deadlines (60s/45s) are the limits that actually govern an
  agent's behaviour and are recorded in conventions/.

request_rate:
  documented: false
  note: No requests-per-second/minute limit is published for any endpoint. Long-poll (observe / play) is the intended pacing — each call blocks up to 25s.
response_headers:
  observed: []
  checked_for: [RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After]
  observed_on: [GET /api/leaderboard (200), GET /api/me (401), POST /mcp tools/list (200)]
  note: None of the seven headers appeared. Responses carry only Cloudflare headers (cf-ray, nel, report-to, alt-svc) and CORS.

    The service runs on Cloudflare Workers behind Cloudflare's edge; per-IP registration counting is
    implemented server-side (source repo src/do/Registry.ts). Cloudflare's own edge protections may
    throttle abusive clients independently — undocumented and unsignalled, recorded as inference only.
