Keio University OAuth Scopes

OAuth 2.0 derived

Keio University uses OAuth 2.0 but publishes no discrete scopes — access is governed by the grant itself (e.g. client-credentials or role-based authorization) rather than per-scope consent.

This index is generated from the provider’s OpenAPI security definitions (and, where available, its documented scope reference) and refreshes on every APIs.io network build. Browse every provider’s scopes at scopes.apis.io.

  Live probes on 2026-09-01 of every Keio surface recorded in apis.yml, plus the OpenID Connect
  discovery document at https://keio.okta.com/.well-known/openid-configuration (HTTP 200).

providerId: keio
description: >-
  Keio University defines no authorization scopes on any surface it operates itself. This file
  records that as a measured absence rather than leaving the artifact out, because the reason
  matters: the two institution-operated APIs — KOARA's OAI-PMH interface and the Media Center's
  IIIF endpoints — are fully anonymous, and an anonymous API has no scope model by construction,
  not by omission. There is nothing to divide because there is nothing to grant.


  The only scope vocabulary reachable anywhere in the estate belongs to Keio's Okta tenant, and it
  is Okta's standard OpenID Connect scope set rather than anything Keio authored. It is recorded
  below with its operator marked, so that it is never read as institutional engineering.

institution_operated:
  scopes: []
  detail: >-
    No scopes. KOARA OAI-PMH and the IIIF Presentation and Image APIs accept unauthenticated
    requests and return complete responses; there is no Authorization header, no token, no consent
    screen and therefore no scope.

tenant_operated:
  - surface: Keio Okta tenant
    issuer: https://keio.okta.com
    x-operator: tenant
    x-operator-evidence: >-
      keio.okta.com is Keio's tenant on the Okta identity platform. The scopes advertised are
      Okta's platform vocabulary, identical for every Okta org, and are not authored by Keio.
    source: examples/keio-okta-openid-configuration.json
    scopes_advertised_note: >-
      The discovery document advertises the standard OpenID Connect scope set (openid, profile,
      email, address, phone, offline_access) together with Okta's org-level scopes. Because these
      are the platform's and not the institution's, they are described rather than enumerated as
      Keio's own — enumerating a vendor's scope list under an institution's slug is the same
      attribution error this pipeline exists to prevent.
    obtainable_by_public: false
    obtainable_detail: >-
      A client_id is created only by Keio IT staff. The discovery document is readable; the
      authorization it describes is not reachable by an unaffiliated caller.
