Hokkaido University (北海道大学) is a national research university in Sapporo, Japan, founded in 1876 as Sapporo Agricultural College, a member of Japan's Designated National University group and ranked #173 in the QS World University Rankings 2025. It operates 12 undergraduate schools, 21 graduate schools and numerous research institutes. Its public programmable footprint is small and honest: the university publishes no developer portal, no API gateway and no documented public REST API — api., data., opendata., developer. and status.hokudai.ac.jp all fail to resolve, and the WordPress REST API on its English site is explicitly disabled. What it does operate, and what this profile is built on, is scholarly identity infrastructure. It runs its own SAML 2.0 / Shibboleth identity provider registered in GakuNin, the Japanese national academic access federation; it holds Handle System prefix 2115 and JaLC DOI prefix 10.14943 for the HUSCAP institutional repository; and it publishes crawlable XML sitemaps for both HUSCAP and its main web estate. HUSCAP's OAI-PMH endpoint is the one real regression: IRDB still harvests the repository by OAI-PMH, but no base URL has been publicly documented since the December 2025 platform migration and eighteen candidate paths were probed unsuccessfully.
Hokkaido University publishes 10 APIs on the APIs.io network. Tagged areas include Education, Higher Education, University, Japan, and National University.
The Hokkaido University catalog on APIs.io includes 1 JSON-LD context.
Hokkaido University’s developer surface includes support, authentication, 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 could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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/hokkaido: open an issue to ask a question, or submit a pull request to add artifacts.

x-coverage:
state: covered
reason: covered
generated: '2026-09-01'
method: probed
detail: 'Every surface class the university pipeline hunts was probed live on 2026-09-01 and the result is a thin but complete
and honest profile. Hokkaido University publishes no public REST API, no developer portal and no API gateway: api., data.,
opendata., developer. and status.hokudai.ac.jp do not resolve, /llms.txt, /.well-known/apis.json, /.well-known/security.txt
and /.well-known/openid-configuration all 404, and the WordPress REST API on the English global site answers {"code":"rest_disabled"}.
What the institution genuinely operates is scholarly identity infrastructure, and that is what this profile now records.
Its own SAML 2.0 / Shibboleth identity provider is registered in GakuNin as PI0008JP with scope hokudai.ac.jp, serves
its metadata from a hokudai.ac.jp host under a certificate issued to O=Hokkaido University, and answers on its advertised
SSO endpoint — the strongest institution-operated surface here and one the June 2026 profile missed entirely. Three further
hokudai.ac.jp SAML service providers are registered alongside it. Persistent-identifier registrations were verified from
the registries themselves rather than from university prose: Handle naming authority 2115, administered from lib.hokudai.ac.jp
and updated 2024-06-24, and JaLC DOI prefix 10.14943, confirmed through the DOI RA resolver and the JaLC API which names
Hokkaido University as publisher. The university is NOT a DataCite member — api.datacite.org returns zero clients and
the library states the position explicitly — and its only Crossref membership is departmental (member 5618, Department
of Mathematics, prefix 10.14492). The one real regression is OAI-PMH: IRDB entry 524 still harvests HUSCAP, so a base
URL exists, but the legacy DSpace endpoint has 404ed since the December 2025 platform migration and eighteen candidate
paths on the replacement platform were probed without success. No vendor contract was saved under this institution''s
name, and none was found to remove — the repo carried no OpenAPI at all before this run.'
