National Yang Ming Chiao Tung University (NYCU) is a public research university in Hsinchu and Taipei, Taiwan, formed in 2021 from the merger of National Yang-Ming University and National Chiao Tung University. Its programmable footprint is small but genuinely its own in one place: the NYCU OAuth service at id.nycu.edu.tw, an OAuth 2.0 (RFC 6749) authorization server run by the university's Information Technology Service Center that lets approved applications authenticate NYCU single sign-on users and read three consented identity attributes. It is documented publicly, in Chinese and English, with its own terms of service and issue tracker, and it is the only contract in this repo NYCU actually engineered. Everything else is a relationship rather than an interface the university wrote. NYCU self-hosts a Dataverse research-data repository and a DSpace institutional repository on its own network, and both expose an anonymous OAI-PMH 2.0 harvesting endpoint that is institution-operated — but the REST contracts underneath them belong to the Dataverse Project and DSpace, not to NYCU. Library discovery is an Ex Libris Primo tenancy. NYCU is a DataCite direct member in its own name, minting DOIs on prefix 10.57770 through its "NYCU Research Data Service" repository, and is registered in ROR. There is no central developer portal, no open-data portal, no course or timetable API, no OpenID Connect discovery document, and no publicly discoverable Shibboleth or SAML identity provider. The course registration and timetable systems are human web applications behind institutional login.
National Yang Ming Chiao Tung University publishes 1 API on the APIs.io network: NYCU OAuth API. Tagged areas include Education, Higher Education, University, Taiwan, and Identity.
The National Yang Ming Chiao Tung University catalog on APIs.io includes 1 Spectral governance ruleset.
National Yang Ming Chiao Tung University’s developer surface includes documentation, API reference, support, and 16 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/nycu: open an issue to ask a question, or submit a pull request to add artifacts.

personal data and must be justified and approved by the Information Technology Service Center — in principle only for
systems the university itself develops or operates. Six documented endpoints. NYCU publishes no machine-readable description
of the service and no discovery document, so the OpenAPI here is derived from the university's own documentation.

own — the OAuth 2.0 service at id.nycu.edu.tw — plus two anonymous OAI-PMH 2.0 endpoints on its own network. The 23 OpenAPIs
previously held here were per-tag splits of ONE document, the Dataverse Project v5.10.1 machine-generated description
captured from dataverse.lib.nycu.edu.tw/openapi; they were removed with everything derived from them because they credited
the Dataverse Project''s engineering to the university. The repository, the DSpace institutional repository and the Ex
Libris Primo discovery layer are kept as tenant relationships, and the DataCite and ROR registrations as registry memberships,
because those are real facts about the institution even where the contract is not theirs. Hunted and not found: a developer
portal (developer.nycu.edu.tw, api.nycu.edu.tw — no DNS), an open-data portal (data.nycu.edu.tw, opendata.nycu.edu.tw
— no DNS), a course or timetable API (timetable.nycu.edu.tw and course.nycu.edu.tw are human web applications, the latter
behind reCAPTCHA and Big5-encoded), a Shibboleth or SAML IdP (idp./sso./shibboleth.nycu.edu.tw — no DNS; id.nycu.edu.tw/saml/metadata
404), an OAuth/OIDC discovery document (both well-known paths 404), a Crossref membership (0 results), and any ORCID integration.
Searched in Traditional Chinese as well as English; the OAuth documentation, terms of service and the university''s generative-AI
guidelines are all Chinese-first surfaces.'
