  Response headers observed on anonymous requests to every HundredX-controlled host

note: >-
  HundredX documents no rate limits, and none were observable at runtime. No RateLimit-*,
  X-RateLimit-*, or Retry-After header appeared on any anonymous response from any host. The
  only throttling in evidence is edge policy, not an API limit: hundredx.com sits behind a
  Cloudflare managed challenge that returns 403 to non-browser clients, and cube-mcp /
  hx-internal-portal / menu-agent sit behind Cloudflare Access. An honest zero — there is no
  public API surface with a published quota to record.
