  City University of Hong Kong (CityUHK) is a publicly funded research
  university located at Tat Chee Avenue, Kowloon, Hong Kong SAR, ranked #55 in
  the QS World University Rankings 2025. Its public, machine-readable developer
  footprint is modest and centered on its research information system: CityUHK
  Scholars, an Elsevier Pure-powered current research information system and
  institutional repository that exposes a publicly harvestable OAI-PMH endpoint.
  An official GitHub organization (github.com/cityu) exists but currently
  publishes no public repositories, and the university operates internal
  identity, portal, and learning systems (AIMS, CAP, Canvas, CityUHK Portal)
  that are gated and not publicly documented as APIs.

    name: CityUHK Scholars Pure Web Service (REST)
    description: >-
      Elsevier Pure REST Web Service backing CityUHK Scholars, an OpenAPI
      3-described CRUD API (GET/PUT/POST/DELETE) for research output, projects,
      persons and related entities. The service is gated: requests require an
      API key in the context of a defined user, and the endpoint returns HTTP
      401 Unauthorized without credentials. The OpenAPI contract is served from
      the instance (/ws/api/openapi.yaml) and an interactive RapiDoc page
      (/ws/api/rapidoc.html) but both require authorization. Not openly
      available; listed for completeness.
