Maastricht University (UM) is a public research university in Maastricht, Netherlands, founded in 1976 and known internationally for its Problem-Based Learning model. Measured honestly, UM operates no API programme: there is no developer portal, no api.maastrichtuniversity.nl, no status page, no published versioning or deprecation policy, and no first-party OpenAPI anywhere on its estate. What it does operate is a small set of standards-based surfaces on its own domain — a live, keyless OAI-PMH 2.0 harvesting endpoint at cris.maastrichtuniversity.nl serving 798,420 records across six metadata profiles including OpenAIRE CERIF 1.2 with resolvable ORCID iDs; a self-hosted GitLab whose REST API answers unauthenticated project queries; and its own ADFS identity provider publishing both OpenID Connect discovery and signed SAML 2.0 federation metadata, with its entity carried in SURFconext and thereby eduGAIN. Everything else that looks like a Maastricht API is a purchase: research data lives in a collection inside the shared national DataverseNL installation, the CRIS is Elsevier Pure, the LMS is Instructure Canvas, and library discovery is OCLC WorldCat. Those are recorded here as tenant relationships, not as Maastricht's engineering.
Maastricht University publishes 1 API on the APIs.io network: Research Portal OAI-PMH. Tagged areas include University, Higher Education, Education, Netherlands, and Europe.
Maastricht University’s developer surface includes GitHub presence, authentication, support, engineering blog, and 26 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/maastricht: open an issue to ask a question, or submit a pull request to add artifacts.

DOIs (prefix 10.34894) are Maastricht''s; the REST contract is upstream Dataverse 6.9''s and is shipped identically by
at least six other institutions in this catalog. The generic Dataverse specification and everything derived from it were
REMOVED from this repository on 2026-08-30 — thirty-six per-tag OpenAPIs, seventy-three collections, and the schemas,
structures, examples, rules, vocabulary, JSON-LD and agentic-access files derived from them — because they described Dataverse''s
engineering, not Maastricht''s. Probing note: dataverse.nl serves an Anubis bot-challenge page to scripted clients on
every path including /api/info/version, so the API is live but unreadable without solving it.'

x-coverage:
state: covered
reason: covered
detail: 'Maastricht University operates no API programme, and this profile now says so. What was catalogued here on 2026-06-03
was upstream Dataverse''s contract: one DataverseNL OpenAPI split by refine-openapis into thirty-six per-tag specifications,
each registered as a separate "Maastricht University <tag> API" entry carrying a fabricated baseURL of https://cris.maastrichtuniversity.nl/ws/oai
— the Pure OAI-PMH endpoint, which is not a Dataverse REST API and does not serve those paths. Thirty-six times the apparent
footprint, on a host that does not run the software, for a contract at least six other institutions in this catalog also
ship. All thirty-six, their seventy-three collections, and every schema, structure, example, ruleset, vocabulary, JSON-LD
context and agentic-access file derived from them were removed on 2026-08-30.
What replaced them is smaller and real. Three institution-operated surfaces were verified live: a keyless OAI-PMH 2.0
endpoint (six verbs, six metadata profiles, 798,420 records, ORCID iDs in the CERIF person records), a self-hosted GitLab
answering unauthenticated project queries, and the university''s own ADFS identity provider publishing OpenID Connect
discovery and signed SAML 2.0 metadata that is carried into SURFconext and eduGAIN. Four purchases were re-labelled as
tenant relationships rather than deleted: DataverseNL, Elsevier Pure, Instructure Canvas and OCLC WorldCat.
Absences confirmed by probe, not assumed: no api., data., open., developer., developers., sis., portal. or status. host
resolves under maastrichtuniversity.nl; no course catalog, timetable or registrar API; no CKAN or Socrata open-data portal;
no institution-operated library API. mdr.datahubmaastricht.nl returns HTTP 200 with an SPA shell on every path including
/openapi.json, which is a soft-200, not an API. dataverse.nl serves an Anubis bot-challenge to scripted clients on every
path — live, but unreadable without solving the challenge, and a vendor''s surface regardless.'
