Utrecht University (Universiteit Utrecht) is a public research university in Utrecht, Netherlands, founded in 1636 and a member of the League of European Research Universities. It is one of the few universities in this catalog whose largest machine-readable surface is its OWN engineering rather than a vendor's: Utrecht authors and operates Yoda, a GPL-3.0 iRODS-based research data management platform (github.com/UtrechtUniversity/yoda-ruleset), and runs it in production at portal.yoda.uu.nl. The Yoda HTTP API is real but not open — every call redirects to SolisID login unless it carries a session cookie or a Yoda data access token — so the OpenAPIs in this repo describe a live institution-operated API that no anonymous client can call. Alongside it the University Library runs a DSpace 9.0 institutional repository whose REST API and OAI-PMH interface are both openly readable at dspace.library.uu.nl, and IT Services operates a SAML 2.0 identity provider registered in the SURFconext federation. The research information system is NOT Utrecht's: research-portal.uu.nl is an Elsevier Pure tenancy (uu.elsevierpure.com), recorded here as a tenant relationship and not as Utrecht's contract. There is no central developer portal, no api.uu.nl, no public course-catalog or campus API, and no published API terms or rate limits; OSIRIS, the student administration system, returns 403 to unauthenticated clients.
Utrecht University publishes 20 APIs on the APIs.io network, including admin API, browse API, data_access_token API, and 17 more. Tagged areas include Education, Higher Education, University, Netherlands, and Europe.
The Utrecht University catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Utrecht University’s developer surface includes authentication, GitHub presence, documentation, API reference, support, and 23 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.
Open Source Surface applies to this provider. This product is open source and we
read its repository directly, so Open Source Surface carries
10 points of the composite. It is scored from what the repository actually
publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the
provider rather than inferred from our own catalog pointers.
This facet adds; nothing was taken away to make room for it. An open-source project is not excused from
the commercial facets, because exemption would strip it of the points it does earn.
If we have the wrong repository, or this product is not open source, say so on your
provider repo and we
will drop the facet rather than have you publish against 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 65 points between them,
because both conditional facets apply and carry
35 points together. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 65% 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/utrecht: open an issue to ask a question, or submit a pull request to add artifacts.

generic OpenAPI is not saved under this slug.
