University of Warsaw

The University of Warsaw (Uniwersytet Warszawski) is Poland's largest and highest-ranked university and a member of the 4EU+ European University Alliance. Unusually for this cohort it operates real first-party programmable surfaces rather than only vendor tenancies: the USOS API at usosapps.uw.edu.pl, a documented OAuth 1.0a REST-like protocol over the institution's own academic database (courses, faculties, calendar, users, payments), and two springdoc services that publish their own OpenAPI and Swagger UI — the Student Portal 4EU+ API at api.sp4eu.uw.edu.pl (OpenAPI 3.1, 74 paths, read endpoints answer anonymously) and Jaskier at api.jaskier.uw.edu.pl, the university's central institutional API (OpenAPI 3.0.1, 729 paths, 458 schemas, bearer-gated data). Research data is handled by two institution-hosted repositories — Dane Badawcze UW (Dataverse, DOI prefix 10.58132) and ReIn UW (DSpace-CRIS 8.1) — each with a native REST API and an OAI-PMH 2.0 endpoint. The university runs its own Shibboleth SAML identity provider at login.uw.edu.pl, registered in eduGAIN through the Polish PIONIER.Id federation, and it is a DataCite repository client and a Crossref member with 31 DOI prefixes. What it does NOT have is a single central developer portal: the USOS developers site is the only signup surface, the library discovery layer is an Ex Libris Alma/Primo tenancy, and the LMS is a Moodle install with no public LTI advertisement.

University of Warsaw publishes 7 APIs on the APIs.io network, including apiref API, apisrv API, calendar API, and 4 more. Tagged areas include Education, Higher Education, University, Poland, and Europe.

The University of Warsaw catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

University of Warsaw’s developer surface includes authentication, GitHub presence, engineering blog, documentation, API reference, support, and 20 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/university-of-warsaw: open an issue to ask a question, or submit a pull request to add artifacts.

x-coverage:
  state: covered
  reason: covered
  detail: 'The University of Warsaw is one of the few institutions in this cohort with genuinely first-party programmable
    surfaces, and every one of them was probed live on 2026-09-01. Two institution-operated API families answer publicly:
    the USOS API at usosapps.uw.edu.pl (machine-readable method reference at services/apiref/method_index, OAuth 1.0a for
    anything beyond anonymous methods) and, newly found in this run, the Student Portal 4EU+ API at api.sp4eu.uw.edu.pl, which
    serves its own OpenAPI 3.1 at /v3/api-docs plus Swagger UI and returns real data anonymously — and behind it Jaskier at
    api.jaskier.uw.edu.pl, the university''s central institutional API, whose OpenAPI 3.0.1 (729 paths, 458 schemas) is public
    while every data endpoint is bearer-gated. Jaskier is linked from no UW developer page; it was found because a Student
    Portal 4EU+ 500 response leaked its upstream URL. Two institution-hosted research repositories expose native REST plus
    OAI-PMH 2.0 (Dane Badawcze UW on Dataverse, ReIn UW on DSpace-CRIS 8.1). The university runs its own Shibboleth SAML IdP
    at login.uw.edu.pl, registered in eduGAIN by PIONIER.Id, and is a DataCite repository client (REPOD.DBUW, prefix 10.58132)
    and Crossref member 4211. Limits worth stating: there is no central developer portal and no open-data portal — no host
    answered at data./dane./otwartedane.uw.edu.pl; library discovery is an Ex Libris Alma/Primo tenancy on the national OMNIS
    catalogue, recorded as a tenant relationship rather than a contract; the LMS is Moodle with no public LTI advertisement;
    and the USOS developer signup page returns HTTP 403 to non-browser clients while rendering the real registration form,
    so it is graded live, not dead.'
