HKBU GenAI Platform API (undocumented, key-gated)
HKBU runs its own generative-AI gateway at genai.hkbu.edu.hk, fronting third-party models (Anthropic, Google, Meta AI, OpenAI) for staff and students. Probing on 2026-08-30 found a live REST surface at /general/rest/deployments/{deployment}/chat/completions and /general/rest/deployments/{deployment}/embeddings, routed internally to /api/v0/rest/* by a NestJS application. It takes an Azure-OpenAI-shaped request and an api-key request header: an unauthenticated POST returns 401 {"message":"API key is missing or invalid."}, and a POST carrying an api-key header returns a distinct 401 {"message":"API key validation failed due to an internal error."}, confirming the header is the credential channel. No OpenAPI, no public developer documentation and no self-service signup were found on any HKBU host; the platform UI is a Next.js SPA behind institutional login. Recorded as an institution-operated surface with no contract saved, because none is published.
