Tsinghua University
Tsinghua University is a leading public research university in Beijing, China, ranked #23 in the QS World University Rankings 2025. Like most Chinese universities, Tsinghua does not operate a centralized public developer portal or documented institutional API program; its student, course, and library systems sit behind campus SSO and are not publicly documented. The most notable public, programmatically accessible service is the TUNA open-source mirror (mirrors.tuna.tsinghua.edu.cn), run by the student TUNA association, which exposes machine-readable JSON status endpoints. A number of Tsinghua research labs (THUNLP, THUML, TUNA, Tsinghua Database Group) maintain active open-source code on GitHub, but these are project repositories rather than an institution-wide API platform.
