Pohang University of Science and Technology (POSTECH) is a private research university in Pohang, North Gyeongsang, South Korea, founded in 1986 by the steelmaker POSCO and consistently ranked inside the QS world top 100. POSTECH operates no developer portal, no open-data program and no API it authored itself — but it is not empty, and three genuinely institution-operated machine-readable surfaces were verified live on 2026-08-30, all of them on POSTECH's own network (141.223.0.0/16). The OASIS institutional repository serves a fully anonymous OAI-PMH 2.0 harvesting endpoint over a corpus of 106,805 records in twelve metadata formats across 163 sets, reaching back to 2014. POSTECH runs its own SAML 2.0 identity provider at idpass.postech.ac.kr, registered in the KAFE federation since 2017 and resolvable through eduGAIN, supporting the REFEDS Research and Scholarship entity category and asserting SIRTFI — machine-readable institutional infrastructure that almost nothing in this cohort catalogues. And POSTECH's LMS publishes a live, public LTI 1.3 Advantage platform keyset and OAuth 2.0 token endpoint, which most institution-hosted Moodles keep unreachable. Everything else is a login wall or someone else's platform: the PODIUM portal, admissions and certificate systems are gated; the DSpace REST interface sits behind a JavaScript bot challenge that returns 200 with a challenge shell; and the thesis pipeline runs through postech.dcollection.net, a tenancy on the KERIS-operated national dCollection platform, recorded here as a relationship rather than as POSTECH's engineering.
Pohang University of Science and Technology publishes 1 API on the APIs.io network: POSTECH OASIS Repository OAI-PMH. Tagged areas include University, Higher Education, Education, South Korea, and Korea.
The Pohang University of Science and Technology catalog on APIs.io includes 1 JSON-LD context.
Pohang University of Science and Technology’s developer surface includes engineering blog, developer portal, authentication, code examples, 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 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/postech: open an issue to ask a question, or submit a pull request to add artifacts.

x-coverage:
state: covered
reason: covered
detail: 'POSTECH publishes no developer portal, no API documentation and no open-data program, and the June 2026 profile
concluded there was one surface here. Re-probed on 2026-08-30 there are four institution-operated surfaces plus one tenancy,
and three of the four are machine-readable without credentials. The OASIS OAI-PMH endpoint answers Identify, ListMetadataFormats,
ListSets and ListRecords anonymously — ListRecords returns real Dublin Core with completeListSize 106,805, which is the
probe that distinguishes a working harvesting surface from a link. POSTECH''s SAML 2.0 identity provider is registered
in eduGAIN through KAFE and its metadata is publicly retrievable from the federation even though the IdP''s own metadata
URL is admin-gated behind a login redirect. The LMS exposes an LTI 1.3 platform JWKS and OAuth 2.0 token endpoint without
credentials. Two things are genuinely closed and are recorded as such rather than as gaps: the DSpace REST interface returns
HTTP 200 carrying a JavaScript bot challenge instead of JSON, and Moodle Web Services answers every anonymous call with
errorcode invalidtoken. No vendor contract has been saved under POSTECH''s name; the dCollection thesis platform is recorded
as a tenant relationship. The Korean-language surface was searched as well as the English one — the privacy and copyright
policies exist on both, and the LMS returns Korean error messages by default.'

x-operator-basis: idpass.postech.ac.kr resolves to 141.223.5.141 inside POSTECH's own network, and the eduGAIN entity record
names POSTECH as the entity with scope postech.ac.kr. An identity provider is institution-operated by definition — it
asserts who is a member of the institution.

with SingleSignOnService and SingleLogoutService under /simplesaml/saml2/idp/, an X.509 signing key, shibmd:Scope postech.ac.kr,
support for the REFEDS Research and Scholarship entity category, a SIRTFI assurance assertion and a REFEDS security contact.
The IdP''s own metadata URL is admin-gated and 302s to a login form, so the federation copy is the public one. The software

x-operator-basis: plms.postech.ac.kr is POSTECH's registrable domain; the host is fronted by a Naver Cloud load balancer,
which is hosting, not operation. The LTI platform identity is POSTECH's — the keys below sign POSTECH-issued id_tokens.
x-contract-origin: The interface is Moodle's implementation of the IMS Global / 1EdTech LTI 1.3 specification, not a POSTECH-authored
contract. No Moodle or LTI specification document is saved under POSTECH's slug; what is recorded here is POSTECH's deployment
of it.
description: POSTECH's learning management system is an institution-hosted Moodle (coursemos distribution) acting as an
LTI 1.3 Advantage platform, and unusually for this cohort its platform endpoints are publicly reachable. The JSON Web
Key Set at /mod/lti/certs.php returns a real RSA RS256 key (kid 13acf24233904ff6db00) with no credentials — the keyset
an external tool needs to verify POSTECH-issued id_tokens — and the paired OAuth 2.0 token service at /mod/lti/token.php
answers an unparameterised request with an RFC 6749 invalid_request object rather than an HTML page. Tool registration
itself is an LMS administrator action and is not open to outside developers.
