University of Twente
The University of Twente (Universiteit Twente, UT), founded in 1961 in Enschede, Netherlands, is a public technical research university. Its programmable footprint is small but, unusually for this cohort, not empty and not borrowed: the university operates one API of its own. The University of Twente Energy API at energyapi.utwente.nl publishes an OpenAPI 3.0.1 contract and a Swagger UI, requires no authentication, and serves historical electricity, gas, heat, water and solar metering for 103 named campus resources — with a CO2-equivalent mode computed against the Dutch national energy mix — from the university's own network. It backs the public Energy Data Platform at energydata.utwente.nl. Around that single owned contract, everything else is a relationship rather than an engineering artifact, and is recorded as such. The university runs its own SAML 2.0 identity provider on a Microsoft Entra ID tenant, registered in the SURFconext national federation with the Shibboleth scope utwente.nl — the strongest institution-operated surface it has after the Energy API. Its library is a Crossref member in its own name (prefix 10.3990). It publishes a live Erasmus Without Paper node declaring fifteen student-mobility APIs scoped to HEI ID utwente.nl. Its research information system, learning management system, student information system and research-data repository are all tenancies on Elsevier Pure, Instructure Canvas, CACI OSIRIS and 4TU.ResearchData respectively — real institutional facts, none of them the university's contract. There is no central developer portal, no API catalog and no published terms for the one API that exists. A previously catalogued OAI-PMH endpoint on the Pure host was re-probed on 2026-09-01 and does not respond; that claim has been corrected rather than carried forward.
University of Twente publishes 1 API on the APIs.io network: Energy API. Tagged areas include University, Higher Education, Education, Technical University, and Netherlands.
The University of Twente catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
University of Twente’s developer surface includes API reference, documentation, support, engineering blog, and 20 more developer resources.

Connect discovery document, both unauthenticated. A federation is shared by definition; the IdP behind it is the institution's,
and this is the surface every gated UT service sits behind. The same tenant GUID appears independently in the canvas.utwente.nl

EWP APIs with every endpoint URL scoped to the HEI ID utwente.nl — institutions, organizational-units, iias, iia-cnr,
iias-approval, iia-approval-cnr, omobilities, omobility-stats, omobility-cnr, omobility-las, omobility-la-cnr, imobilities,
imobility-cnr, factsheet and discovery itself. EWP is the European Commission-backed machine-to-machine network for Erasmus+
student mobility. By operation count this is the university's largest declared API surface. It is recorded as tenant rather
than institution because the platform is SOP's Mobility-Online (the manifest's admin contact is ewp@sop.co.at, the host
resolves to 77.237.55.133 outside UT address space) and the API contracts are the EWP consortium's shared specifications
— the deployment and the data are the university's, the engineering is not.

recorded rather than credited as the university''s engineering — Elsevier Pure, Instructure Canvas, CACI OSIRIS, 4TU.ResearchData
and an SOP Mobility-Online EWP node. What is genuinely absent is a central developer portal, an API catalog, published
terms or rate limits for the one API that exists, and any public course, timetable, transit, dining or room-booking API;
the authoritative course data sits behind OSIRIS login. One prior claim was retired: the Pure OAI-PMH endpoint this repo
