Tsinghua University (清华大学) is a public national research university in Beijing, China, a member of the C9 League and the Double First-Class construction programme, and one of the highest-ranked universities in Asia. Its programmable footprint is small, real, and almost entirely invisible from outside the campus network. Tsinghua operates no developer portal, no open data portal and no API key issuance of any kind: api.tsinghua.edu.cn, open.tsinghua.edu.cn and data.tsinghua.edu.cn do not resolve. Every system the university runs for its own community — the learning platform (learn.tsinghua.edu.cn), course registration (zhjwxk.cic.tsinghua.edu.cn), the institutional GitLab (git.tsinghua.edu.cn), Tsinghua Cloud (cloud.tsinghua.edu.cn), the information portal and the campus card — terminates at one electronic identity service, id.tsinghua.edu.cn, and is unreachable without institutional affiliation. What Tsinghua does publish, unauthenticated and machine-readable, is three things, and all three are the institution's own rather than a vendor's. First, the TUNA open-source mirror (mirrors.tuna.tsinghua.edu.cn), run by the student TUNA association on the university's own domain and infrastructure, which serves two live JSON documents: the tunasync synchronization status of every mirrored repository, and a catalog of the installable images for 66 distributions, font collections and applications. Second, and more consequential for a university, Tsinghua runs its own Shibboleth Identity Provider at idp.tsinghua.edu.cn and publishes SAML 2.0 federation metadata about it — entityID https://idp.tsinghua.edu.cn/idp/shibboleth, shibmd:Scope tsinghua.edu.cn — with every SingleSignOnService and SingleLogoutService location resolving to a Tsinghua host rather than to a federation vendor. Third, the university library holds a DataCite direct membership in its own name (symbol TSINGHUA, joined 2016) under which 194 DOIs are registered on prefix 10.23650, resolving to datacite.lib.tsinghua.edu.cn. Two honest qualifications belong in this description. The DOI landing-page host completes TCP and TLS but returns nothing to an HTTP GET after 60 seconds from outside China, so those 194 DOIs are registered but unresolvable from here. And the mirror's edge answers HTTP 403 to requests carrying a desktop-browser User-Agent while answering the same request 200 for a plain tool User-Agent — the inverse of the usual bot filter, and enough to lock out any agent that spoofs a browser. Notably, Tsinghua holds no Figshare, Elsevier Pure, Symplectic, Ex Libris or Dataverse tenancy that could be found: unlike most of this cohort, there is no vendor contract masquerading as this institution's engineering. Tsinghua research groups (THUDM, THUNLP, THUML, TUNA) publish substantial open-source code on GitHub, but those are project repositories, not an institutional API programme, and they are recorded as pointers rather than as surfaces.
