Delft University of Technology

Delft University of Technology (TU Delft) is the oldest and largest public technical university in the Netherlands and a member of the 4TU.Federation. Its programmable footprint is narrow, and this profile states that plainly rather than padding it. TU Delft operates exactly one public, unauthenticated API: the 4TU.ResearchData repository at data.4tu.nl, which runs on djehuty, open-source repository software written by 4TU.ResearchData and Nikhef. The /v2 surface is deliberately shape-compatible with the Figshare v2 API because that was a requirement of the 2023 migration OFF Figshare — the contract is not Figshare's, and the service runs inside TU Delft's own RIPE netblock (DUNET, 131.180.0.0/16). The other genuinely institution-operated machine-readable surface is a SAML 2.0 identity provider at login.tudelft.nl, published into the SURFconext national federation and onward to eduGAIN. Beyond those two, the picture is retirement and tenancy. The general-purpose institutional API platform at api.tudelft.nl — campus, buildings, courses, schedules, study results, organisation — no longer answers on port 80 or 443, and its documentation host apidoc.tudelft.nl has no DNS record at all. The research information portal at pure.tudelft.nl / research.tudelft.nl is an Elsevier Pure tenancy whose own API documentation canonicalises to api.elsevierpure.com: TU Delft's data, Elsevier's contract. The library discovery layer is an OCLC WorldCat tenancy. No working OAI-PMH endpoint exists on any TU Delft-operated host despite third-party registry entries claiming otherwise. TU Delft publishes no OpenAPI, no llms.txt, no scope vocabulary and no API changelog.

Delft University of Technology publishes 4 APIs on the APIs.io network, including Account API, Collections API, Datasets API, and 1 more. Tagged areas include University, Higher Education, Education, Technical University, and Research Data.

The Delft University of Technology catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Delft University of Technology’s developer surface includes documentation, API reference, engineering blog, support, authentication, and 35 more developer resources.

scored 2026-09-08 · rubric v0.20.0
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/tu-delft: open an issue to ask a question, or submit a pull request to add artifacts.

x-coverage:
  state: covered
  reason: single_institutional_api_plus_federation_identity
  detail: 'The institution''s programmable surface was probed directly rather than inferred. One public institutional API
    was found and verified live (4TU.ResearchData, twelve endpoints answering HTTP 200/403/405 without credentials), and one
    machine-readable identity artifact was found and retrieved (SAML 2.0 IdP metadata, cross-confirmed in the live SURFconext
    aggregate). Three previously catalogued surfaces did not survive probing: the api.tudelft.nl platform is unreachable on
    both ports with its documentation host removed from DNS, and neither claimed OAI-PMH interface exists — data.4tu.nl returns
    a JSON 404 on every OAI path, and repository.tudelft.nl returns its soft-404 chrome on every OAI path over http and https,
    while the base URL OpenAIRE advertises for it belongs to TNO''s repository. One genuine tenant relationship the June 2026
    profile missed entirely was found and recorded rather than deleted: the Elsevier Pure instance at pure.tudelft.nl. The
    profile is thin because TU Delft''s public programmable footprint is thin, not because the hunt was short.'

    by definition and almost never get catalogued for: it is institution-run, machine-readable, and it is what actually lets
    a researcher at another institution authenticate against a TU Delft service. Note what it is NOT — there is no OpenID

    OAI-PMH interface at /ws/oai (HTTP 401 — the interface exists and is gated, not absent). RECORDED AS A RELATIONSHIP, NOT
    A CONTRACT. The publications, people and project data are TU Delft's; the API surface that carries them is Elsevier's
    product and belongs on Elsevier's own scorecard. No Pure specification is saved into this repository, and nothing is derived
    from one. This entry exists so that a real institutional fact — TU Delft is a Pure customer — is on the record without
    a vendor's contract being credited to the university.
