# USTC Course Catalog API (catalog.ustc.edu.cn)

USTC Course Catalog API (catalog.ustc.edu.cn) is one of 6 APIs that [University of Science and Technology of China](https://apis.io/providers/ustc/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Course Catalog, Registrar, Timetable, and Gated. The published artifact set on APIs.io includes API documentation and authentication docs.

The JSON API behind USTC's public course catalog application — semesters, the college tree, program trees, course search, course and lesson detail, exam lists, major lists and public timetables, across eighteen routes under /api/teach/. It is institution-operated and live, but every data route answers 401 to an unauthenticated caller, and the application's own /api/restricted route returns {"restricted":true}, so the catalog is in a declared restricted mode rather than merely unauthenticated. Recorded because a registrar/timetable API is one of the few surface classes a university genuinely runs itself, and because this one is real, routed and USTC's own — not a student project on an outside domain.
