HKUST Path Advisor API
Public, keyless JSON API behind HKUST Path Advisor, the university's campus wayfinding service. Serves the campus spatial model: 7 buildings, 43 calibrated floor plans with metres-per-pixel and origin offsets, 26 point-of-interest categories, and named nodes carrying GeoJSON MultiPolygon footprints. Runs on HKUST's own domain and network (pathadvisor.ust.hk, 143.89.15.35), names no vendor anywhere in its responses or headers, and answers unauthenticated with Access-Control-Allow-Origin *. One route, /connectors, is gated behind an unpublished authorization scheme. HKUST publishes no OpenAPI for it; the description in this repository was written from live probes on 2026-08-30 and is a third-party observation, not an HKUST artifact.
