description: >-
  ANU is a non-commercial higher-education institution and sells no API access. Everything it
  operates publicly is free. Corrected 2026-08-19: the previous version of this file described
  free "library, repository, course, and open-metadata interfaces" — ANU operates no public
  library API and no public course API, so those were struck. The three plans below reflect
  only surfaces confirmed by live probe: a free self-serve API key for the ANU Quantum Numbers
  service, unauthenticated open access to the deprecated legacy RNG endpoint and to OAI-PMH
  harvesting, and affiliation-gated access to everything else behind Australian Access
  Federation single sign-on.
notes: >-
  method: probed. No published per-seat or per-call pricing exists, and no paid tier was found
  on any ANU surface. "Affiliation / Credentialed" is access gated by institutional identity
  rather than payment — there is no way for an unaffiliated developer to buy into it.
