Tsinghua University DataCite DOI Registration and Resolution is one of 4 APIs that [Tsinghua University](https://apis.io/providers/tsinghua/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Research Data, DOI, DataCite, Library, and Persistent Identifiers.

Tsinghua University holds a DataCite membership in its own name — symbol TSINGHUA, memberType direct_member, organizationType academicInstitution, joined 2016-09-05, registered against the university library — under which 194 DOIs are minted on prefix 10.23650. The landing pages resolve to Tsinghua's own host, datacite.lib.tsinghua.edu.cn, so this is an institution-operated DOI service rather than a tenancy on a vendor repository platform, which is unusual and worth noting for this cohort. Two caveats are load-bearing. The resolution host does not answer HTTP from outside China: TCP 443 is open and the TLS handshake completes against a valid Let's Encrypt certificate for *.tsinghua.edu.cn, but a GET returns zero bytes after 60 seconds, and doi.org redirects into the same dead end — so these DOIs are registered but unresolvable from here. And the two repository clients under the membership are TSINGHUA.NGAC ("China Geological Survey", 2017) and TSINGHUA.KUKSIK ("test", 2021); the DOI content observed is Chinese national geological-survey data curated by Tsinghua, not a general institutional research-data repository. Tsinghua registers no repository in re3data at all. No contract is saved under this entry — the machine-readable evidence lives in DataCite's own API, which is DataCite's contract, not Tsinghua's.
