National Tsing Hua University (NTHU) is a national public research university in Hsinchu, Taiwan, founded in Beijing in 1911 and re-established in Taiwan in 1956. It has no central developer portal, no API catalog and no institution-wide API program, and this profile is deliberately small because the honest footprint is small. It does, however, hold something most of this cohort does not: one genuinely institution-operated, institution-governed API. NTHU's Computer and Communication Center runs an OAuth 2.0 authorization and identity service at oauth.ccxp.nthu.edu.tw, fronting the Academic Information System (CCXP), documented by the university in its own interface manual, governed by a regulation passed by the Computer and Communication Committee in December 2020, and carrying a published scheduled repeal date of 2027-07-31. It is not self-service — a request needs a unit head's signature, Computer and Communication Center review, and sign-off from every unit that owns a requested data field — but it is NTHU's own engineering on NTHU's own host. Everything else programmable that carries NTHU's name is operated by someone else. The widely cited NTHU Data API, a live FastAPI service with an OpenAPI 3.1.0 description and 22 keyless public paths over campus announcements, buses, courses, departments, dining, energy, library spaces, locations and newsletters, is built and hosted by the NTHU Student Association on nthusa.tw, not by the university on nthu.edu.tw. The research portal at scholars.nthu.edu.tw is an Ex Libris Esploro tenant, and the library discovery service is an Ex Libris Primo VE tenant shared through the University System of Taiwan consortium. Those are real institutional facts and they are recorded as tenant relationships, but they are not NTHU's contracts and are not scored as such.
National Tsing Hua University publishes 2 APIs on the APIs.io network: NTHU Academic Information System OAuth 2.0 Service and NTHU Data API. Tagged areas include Education, Higher Education, University, Taiwan, and Public Research University.
The National Tsing Hua University catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
National Tsing Hua University’s developer surface includes documentation, API reference, support, GitHub presence, authentication, and 24 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Education & Research regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/nthu: open an issue to ask a question, or submit a pull request to add artifacts.

NTHU sources, but it is not published, hosted or supported by the university.

and unit newsletters. It publishes its own OpenAPI description at /openapi.json (serving 3.1.0 as of 2026-08-30; the archived
pristine copy in openapi/_original/ declares 3.0.3, so upstream has since bumped its emitted version) and Swagger UI at

detail: 'National Tsing Hua University operates exactly one API of its own and it was found, documented and probed: the
Computer and Communication Center''s OAuth 2.0 service at oauth.ccxp.nthu.edu.tw/v1.1, with a published interface manual,
a governing regulation adopted 2020-12-22 and a scheduled repeal of 2027-07-31. Everything else in this repo is now correctly
attributed away from the institution. The nine OpenAPI documents previously listed as nine separate NTHU APIs are one
contract, the NTHU Data API, and it is operated by the NTHU Student Association on nthusa.tw rather than by the university
— recorded here as a single tenant surface rather than deleted, because the relationship is real. Two vendor platform
tenancies were found and recorded without saving a vendor contract: an Ex Libris Esploro research portal on the NTHU-owned
host scholars.nthu.edu.tw, and an Ex Libris Primo VE library discovery service on an Ex Libris host under the University
System of Taiwan view 886UST_NTHU. Hunted and not found: no data./opendata./api. host under nthu.edu.tw resolves at all;
NTHU has no eduGAIN entry and no Taiwanese registration authority appears in the eduGAIN entity list; the OAI-PMH service
exists but returns 403; the Esploro portal answers every path with the same 2,328-byte SPA shell. Searched in Traditional
Chinese as well as English, which is how the OAuth governance regulation and both AI-policy documents were found.'
