Chulalongkorn University is Thailand's oldest public research university, founded in 1917 in Bangkok. Its programmable footprint is small, real, and almost entirely undeclared: there is no developer portal, no open data portal, no published specification of any kind, and no self-service registration anywhere in the estate. What it does operate are two genuine institution-run surfaces. Chula SSO at account.it.chula.ac.th has been in production since January 2017 and is documented endpoint-by-endpoint on a public wiki — a modified CAS 1.0 protocol with an added application-authentication step, backed by the university LDAP directory, with keys issued by email rather than by a console. The Office of the Registrar's CU-REG Course Schedule application answers unauthenticated JSON at cas.reg.chula.ac.th/class/api for its curriculum register and build version, though the thirteen further endpoints its own client declares return 404 from outside the campus network. Everything else that looks like a Chulalongkorn API belongs to somebody else: Chula Digital Collections, which serves the university's only working OAI-PMH endpoint, is a bepress Digital Commons tenancy (digital.car.chula.ac.th is a CNAME to dcchula.bepress.com, adminEmail dc-support@elsevier.com); federated login is a Microsoft Entra ID tenant; DOIs are registered through DataCite and, faculty by faculty, through eleven separate Crossref member records. The institution's own DigiVerse repository publishes no machine-readable interface at all, and the previously recorded claim that it is a DSpace deployment exposing DSpace REST and OAI-PMH does not survive probing. The central data exchange, CU Data Gateway, is restricted to assigned university personnel and unreachable from outside the campus network.
Chulalongkorn University publishes 23 API contracts indexed on the APIs.io network, including Curriculum API, Meta API, About API, and 20 more. Tagged areas include Education, Higher Education, University, Research, and Thailand.
The Chulalongkorn University catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Chulalongkorn University’s developer surface includes API reference, documentation, authentication, support, GitHub presence, and 14 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/.

It is institution-hosted: digiverse.chula.ac.th resolves directly to 161.200.145.7, in the same university block as car.chula.ac.th,
with no CNAME to any vendor. It publishes no machine-readable interface. A prior profile recorded DigiVerse as a DSpace
deployment exposing DSpace REST at /server/api and OAI-PMH at /server/oai — that is corrected here: the application is
a PHP/AngularJS stack (nginx, PHPSESSID, CodeIgniter 404 pages) and /server/api, /rest/api, /api/, /digital/api/ and both
OAI-PMH paths all return 404. Its own robots.txt disallows /api/ and /digital/api/, so an API layer exists behind the
application; none of it is publicly reachable or documented.'
