summary: >-
  Avalix publishes no request-rate limit for the Autonoma API — no requests-per-window number, no
  X-RateLimit-*/RateLimit-* headers in the OpenAPI, and none observed live. The only rate-limit signal is a
  tag: the A2A card marks the free Trust Preview skill "rate-limited" without a number. Twelve rapid
  unauthenticated POSTs to /v1/trust/preview on 2026-09-19 all answered 400 with no rate-limit or
  Retry-After header, so the exhaustion behaviour could not be observed either. What the provider DOES
  publish are input-size ceilings and payment time windows, recorded below as size_and_time_limits rather
  than counted as rate limits.
