note: >-
  No rate limits are published because Abre publishes no public API. A help-center search for
  "API" returns six articles, all of them guides for APIs Abre CONSUMES (OneRoster 1.1, ClassLink,
  SchoolDay/GG4L, third-party assessment feeds, a Google OAuth allow-list). A search for "webhook"
  returns zero articles. No quota, window, burst, 429 behaviour or RateLimit-* / X-RateLimit-* /
  Retry-After response header is documented anywhere on Abre's public surface, and there is no
  unauthenticated endpoint on which to observe one. This is an honest zero, not an unchecked field.
