HKU ITS API Developer Portal and Gateway

HKU Information Technology Services runs an Azure API Management gateway at api.hku.hk and a developer portal at developer.hku.hk. Since 17 March 2026 the portal has issued subscription keys to students as well as staff for chat-completion, embedding and image-generation APIs across several hosted models. The gateway is live and answers in the APIM error envelope ({"statusCode":404,"message":"Resource not found"}), but every portal route — /apis, /docs/services — redirects to /signin, so the API catalog, its specifications, its scopes and its rate limits are not publicly enumerable. Catalogued as a real institution-operated surface whose contract is not published, not as an absence.

  for HKU (developer-hku-hk-*.z01.azurefd.net, api-hku-hk-*.z01.azurefd.net). The APIs behind the gateway
