description: >-
  Hong Kong Baptist University publishes no rate-limit documentation for any surface it operates.
  Re-probed 2026-08-30: the GenAI Platform gateway, the Moodle LTI/web-services endpoints and the
  mobile-app backend are all credential-gated and return no RateLimit-* or X-RateLimit-* headers to
  an unauthenticated caller, so no limit could be observed. The Shibboleth IdP metadata document is
  served anonymously with no throttling advertised. The only rate-limited surface under HKBU's name
  is the Elsevier Pure Web Service at scholars.hkbu.edu.hk, whose limits are Elsevier's product
  limits and are not credited to the institution. No limits are asserted here that were not observed.
notes: >-
  Revised 2026-08-30. The prior version named OAI-PMH, IIIF and library harvesting limits; HKBU
  operates no IIIF or library harvesting surface, and its only OAI-PMH endpoint is Pure's and returns
  401. Those claims were removed rather than restated.
