Zhejiang University (浙江大学, ZJU) is a comprehensive public research university in Hangzhou, Zhejiang Province, China — a C9 League and Double First-Class institution, ranked in the QS World University Rankings top 50, with strengths across AI, engineering, medicine, agriculture and the sciences. ZJU operates no central developer portal, no open data portal, no institution-operated research data repository and no documented public application API. Its verified institution-operated programmable footprint is three surfaces, all under its own zju.edu.cn registrable domain: a public open source software mirror at mirrors.zju.edu.cn that publishes a genuinely machine-readable service catalog (the MirrorZ data contract, 63 mirrored repositories, anonymous read); a Shibboleth SAML 2.0 Identity Provider registered in CARSI and reachable through eduGAIN; and a CAS unified single sign-on platform. Everything else on the public estate is either vendor software running on a ZJU hostname — the Huiwen library catalog, the undergraduate teaching management platform, the faculty profile system — or is gated behind campus network access. The library catalog has been deliberately withdrawn from the public internet. No OpenAPI, AsyncAPI, GraphQL, MCP server, agent card, robots.txt, security.txt or llms.txt is published anywhere on the institution's own surface.
Zhejiang University publishes 2 APIs on the APIs.io network: Catalog API and Repositories API. Tagged areas include University, Higher Education, Education, Research, and China.
The Zhejiang University catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Zhejiang University’s developer surface includes documentation, support, authentication, and 23 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 does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% 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/zhejiang: open an issue to ask a question, or submit a pull request to add artifacts.

x-coverage:
state: covered
reason: institution_surface_verified
detail: 'Three institution-operated surfaces confirmed live under Zhejiang University''s own registrable domain zju.edu.cn,
one of which publishes a real machine-readable contract: the MirrorZ service catalog at mirrors.zju.edu.cn/mirrorz.json
(200, application/json, 63 mirrors, validated against the upstream MirrorZ JSON Schema). The SAML 2.0 / Shibboleth IdP
at idp.zju.edu.cn is institution-operated and third-party-registered in eduGAIN via CARSI, evidencing two education-regime
domain standards — though the document it serves is an expired, uncustomised installer artifact. Two further surfaces
are real institutional facts but are gated: the library catalog at opac.zju.edu.cn returns a deliberate 403 stating public-internet
service has been suspended in favour of WebVPN, and the undergraduate teaching platform at zdbk.zju.edu.cn is a login-only
vendor system. NO tenant relationship on a research-data platform was found — there is no Figshare, Pure, Dataverse, DSpace
or Symplectic surface under zju.edu.cn, so no vendor contract is attributed here. There is no open data portal, no institution-operated
OAI-PMH endpoint (libweb.zju.edu.cn soft-404s on /oai, returning HTTP 200 with a CMS error body — deliberately not credited),
and no central developer portal.'

description: 'Zhejiang University operates a Shibboleth SAML 2.0 Identity Provider, entityID https://idp.zju.edu.cn/idp/shibboleth,
registered in CARSI (the CERNET Authentication and Resource Sharing Infrastructure) and interfederated through eduGAIN

1.0, SAML 1.1, SAML 2.0 and the Shibboleth-native binding. Caveat recorded honestly: the metadata served at the entityID
is the unmodified Shibboleth installer artifact — validUntil 2020-01-29, expired for six years, with no Organization or
ContactPerson block and the template placeholders still commented in. Federated consumers work from the CARSI/eduGAIN
aggregate, not from this endpoint.'
