The University of Bonn (Rheinische Friedrich-Wilhelms-Universitaet Bonn), founded in 1818, is a public research university in North Rhine-Westphalia, Germany, and a member of the German Universities Excellence Initiative. Like every institution it is a federation of buyers rather than an API producer, but it is an unusually self-hosted one: the surfaces in this profile run on the university's own hosts, inside its own computing centre, rather than on a vendor's multi-tenant platform. bonndata, the institutional cross-disciplinary research data repository, runs Dataverse 6.7.1 at bonndata.uni-bonn.de (CNAME bonndata-produktiv.rhrz.uni-bonn.de, 131.220.213.19) and exposes a genuinely public, anonymous, read-only REST API — /search, /datasets, /datasets/export, /info/version, /info/metrics — plus a full OAI-PMH 2.0 endpoint; every documented path was re-verified live on 2026-09-01 and /search returned 376 indexed datasets. bonndoc, the university publication server at bonndoc.ulb.uni-bonn.de, answers OAI-PMH in ten metadata formats. The university runs its own Shibboleth Identity Provider at shibboleth.uni-bonn.de and is the only uni-bonn.de entity in the 11,457-entity DFN-AAI federation aggregate. It self-hosts GitLab at gitlab.uni-bonn.de, whose REST API v4 answers anonymously across 195 public projects, and keeps a GitHub organization at github.com/unibonn. It is a DataCite member (BXBQ) minting DOIs under prefix 10.60507 through the bonndata repository client, is registered in ROR as 041nas322 and in re3data as r3d100014222. What it does NOT have is equally clear and is stated here rather than padded: no central developer portal, no institution-authored OpenAPI or AsyncAPI, no llms.txt, sitemap.xml, apis.json or agent card on any host it controls, no public course, timetable or student-information API (BASIS runs HISinOne behind sign-in, eCampus runs ILIAS), and no institutional open-data portal — opendata.bonn.de belongs to the City of Bonn, not the university. Library discovery (bonnus) is Ex Libris Primo, self-hosted on a university IP, with no public API. The four OpenAPI documents in this repo are API-Evangelist-authored descriptions of the public read subset of the Dataverse Native API as deployed by Bonn; the Dataverse contract itself belongs to the Dataverse project, and no vendor specification is saved under this institution.
University of Bonn publishes 12 API contracts indexed on the APIs.io network, including Datasets API, Info API, Metrics API, and 9 more. Tagged areas include University, Higher Education, Education, Germany, and Public Research University.
The University of Bonn catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
University of Bonn’s developer surface includes documentation, support, engineering blog, authentication, and 22 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/.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

x-coverage:
state: covered
reason: covered
detail: 'Bonn is one of the thin-cohort exceptions: it operates a real, anonymous, public read API on its own host and it
was fully reachable. Every path in the four OpenAPI documents was re-probed on 2026-09-01 and returned 200 with the expected
payload (/search 376 datasets, /search/services, /info/version 6.7.1 build 1955-8e18f64, /info/metrics/datasets 376, /datasets/:persistentId,
/datasets/export?exporter=oai_dc), and both institution OAI-PMH endpoints answered verb=Identify. Two honest limits are
recorded rather than smoothed over. First, the HTML side of bonndata and bonndoc sits behind an Anubis bot challenge that
answers HTTP 200 with a 7,540-byte "Making sure you''re not a bot!" page — so /openapi, /llms.txt and /.well-known/agent.json
all return 200 while carrying nothing, and none of them is credited here; the /api and /oai paths are unaffected. Second,
the ULB digital collections host (digitale-sammlungen.ulb.uni-bonn.de) returns a hard 403 to every request including its
OAI path, so whatever IIIF or harvesting surface it runs could not be read. What is absent is absent, not unreachable:
no llms.txt, sitemap.xml, apis.json or agent card exists on www.uni-bonn.de (all 404), and there is no developer portal
to gate.'

aggregate at https://mdq.aai.dfn.de/entities/ carries 11,457 EntityDescriptors and exactly ONE uni-bonn.de entity — this
IdP — with registrationAuthority https://www.aai.dfn.de, mdui:DisplayName "Universitaet Bonn", shibmd:Scope uni-bonn.de,
entity attributes DFN-AAI-IdP and http://aai.dfn.de/category/idm.nrw-member, and a valid XML signature. Per-entity MDQ
lookup answers 200 application/samlmetadata+xml. SSO is bound over HTTP-POST, HTTP-POST-SimpleSign and HTTP-Redirect;
SLO adds SOAP; an ArtifactResolutionService runs on port 8443. This is the strongest institution-operated machine-readable
surface Bonn has and it was absent from the June 2026 profile.'
