The University of Freiburg (Albert-Ludwigs-Universität Freiburg) is a public research university in Baden-Württemberg, Germany, founded in 1457, a member of the German U15 and ranked #212 in the QS World University Rankings 2025. Like most universities it operates no central developer portal, publishes no OpenAPI description of anything, and offers no API program, keys, plans or support channel for developers — but unlike most of the cohort a meaningful part of what it does run is genuinely its own rather than a vendor contract wearing its name. Its library (Universitätsbibliothek Freiburg) operates FreiDok plus, an institutional repository and university bibliography whose read-only JSON API and OAI-PMH 2.0 endpoint are open, anonymous and live (267,771 publications, 238,730 persons, 1,277 institutions and 10,612 projects as probed on 2026-09-01). The university also runs a FreiData research-data repository (an InvenioRDM deployment minting DataCite DOIs under its own prefix 10.60493), a self-hosted GitLab whose REST API answers anonymously for 56 public projects, a public status page with a JSON monitor feed, and its own Shibboleth/SAML Identity Provider published into the DFN-AAI national federation. Its library discovery catalog is live but IP-blocked to automated clients, and its campus-management and LMS systems (HISinOne, ILIAS) are human-facing only. Everything programmable here is read-only metadata infrastructure built for harvesting, not a product; there is nothing to sign up for and nothing to buy.
University of Freiburg publishes 1 API on the APIs.io network: FreiDok plus JSON API. Tagged areas include Education, Higher Education, University, Research, and Research Data.
The University of Freiburg catalog on APIs.io includes 1 JSON-LD context.
University of Freiburg’s developer surface includes status page and 18 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/.

detail: 'Probed on 2026-09-01 with a browser user-agent. Six institution-operated machine-readable surfaces were verified
live under uni-freiburg.de, one identity-federation surface and two registry memberships were evidenced, and every pointer
in this file was re-fetched. The footprint is real but narrow: it is research-metadata and infrastructure plumbing, with
no developer program, no authentication, no published contract of the institution''s own, and two of the live surfaces
(GitLab, the Uptime Kuma status feed) are off-the-shelf products the university merely hosts — their contracts belong
to those products, not to Freiburg, so only the in-house FreiDok plus API is described by an OpenAPI here. One surface
is unreadable: katalog.ub.uni-freiburg.de returns 403 with an explicit IP-range bot block. No vendor contract has been
attributed to the institution, and no contract is saved for any surface the institution did not itself build.'
