description: 'Nanjing University (NJU, 南京大学), founded in 1902 in Nanjing, Jiangsu, is one of China''s oldest research universities
and a member of the C9 League. It publishes no developer portal, no API gateway, no API programme and no OpenAPI of its
own, and this profile records that plainly. What it does operate — directly, on its own hosts, inside CERNET address space
— is a genuine estate of institution-run machine-readable surfaces, almost all of it built and run by the university''s
e-Science Center: its own Shibboleth identity provider at idp.nju.edu.cn, registered in CARSI and republished to eduGAIN;
a CAS single sign-on service whose ticket-validation endpoints answer the CAS 2.0 and 3.0 protocol to anonymous callers;
a public open-source mirror at mirrors.nju.edu.cn serving JSON configuration endpoints; a GitLab instance at git.nju.edu.cn
whose REST API v4 the mirror site itself consumes; a BookStack documentation service at doc.nju.edu.cn that publishes a
complete 79-endpoint REST API reference publicly and gates the API on an NJU token; and Seafile, SeaTable and Vaultwarden
deployments that answer unauthenticated service-discovery JSON. None of this is an API product, none of it is registerable
by an outsider, and the contracts behind the service deployments are the upstream products'', not NJU''s engineering — so
no vendor specification is saved here under NJU''s name. The June 2026 profile of this institution saw none of it and recorded
only a login page.'

detail: 'Nanjing University operates a real, verified estate of institution-run machine-readable surfaces, all of it probed
live on 2026-09-01 and all of it on hosts inside CERNET address space under nju.edu.cn: its own Shibboleth IdP (registered
in CARSI and eduGAIN since 2020-02-18), CAS ticket validation answering the CAS 2.0/3.0 protocol anonymously, the NJU
Mirror JSON configuration endpoints, a GitLab REST API v4 the university''s own site consumes, a BookStack service publishing
79 documented REST endpoints and gating them on an NJU token, and Seafile / SeaTable / Vaultwarden deployments answering
unauthenticated service-discovery JSON. What NJU does not have is equally definite and is stated rather than padded: no
developer portal, no API gateway, no API key or client registration, no published API terms, no OpenAPI, no robots.txt,
no sitemap.xml, no llms.txt and no .well-known/security.txt on the main site (all 404), no OIDC discovery on the CAS server,
no OAI-PMH endpoint, no DataCite or Crossref membership, and no institutional repository host that resolves. Three surfaces
are gated rather than absent and are recorded as findings: the library OPAC is restricted to the campus network (403,
"use the NJU VPN"), git.nju.edu.cn answers non-browser clients with an Anubis bot challenge, and data.nju.edu.cn and elearning.nju.edu.cn
return HTTP 483 maintenance pages from an edge WAF. One vendor tenancy the library still links — the Summon discovery
instance at nju.summon.serialssolutions.com — returns 404 on every path and was therefore not recorded as a live surface.
No vendor contract is saved under NJU''s name: the Seafile, SeaTable, Vaultwarden, GitLab and BookStack contracts belong
to those products, and only the deployments are credited here. On AI, NJU''s public posture is curricular rather than
regulatory — it launched mandatory AI general-education core courses for the class of 2028 in September 2024 and runs
its own assistant platform at chat.nju.edu.cn — but no institution-wide generative-AI usage policy was found on a public
NJU surface in either English or Chinese, so no AIPolicy pointer is claimed.'
