Charles University (Univerzita Karlova), founded in 1348 in Prague, is the largest and oldest university in Czechia. Unusually for a university, a substantial part of its programmable footprint is genuinely institution-operated rather than a vendor contract running under its name. The Institute of Formal and Applied Linguistics (UFAL) in the Faculty of Mathematics and Physics runs the LINDAT/CLARIAH-CZ research infrastructure and publishes five documented, keyless, production REST APIs on its own host — machine translation, UDPipe (tokenization, tagging, lemmatization and dependency parsing across 961 Universal Dependencies models), NameTag (named-entity recognition), MorphoDiTa (morphological analysis and generation) and Korektor (Czech spellchecking and diacritics). Three DSpace repositories on university-owned infrastructure expose OAI-PMH 2.0, and the LINDAT repository additionally exposes a DSpace 7 HAL REST API. The university operates its own Shibboleth SAML identity provider at idp.cuni.cz, registered in the Czech national federation eduID.cz, and is a DataCite registrant (CUNI) and Crossref member. What it does NOT have is a central developer portal, an open-data portal, or any public API over the Study Information System (SIS) or student records — those are gated behind eduID/Shibboleth. Library discovery (UKAZ) is an Ex Libris Primo tenancy and cuni.figshare.com is a Figshare tenancy; both are real institutional relationships whose contracts belong to the vendors.
Charles University publishes 7 APIs on the APIs.io network, including LINDAT Translation Languages API, LINDAT Translation Models API, LINDAT Translation Root API, and 4 more. Tagged areas include University, Higher Education, Education, Research, and Czechia.
The Charles University catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Charles University’s developer surface includes documentation, API reference, support, GitHub presence, authentication, and 19 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 applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% 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/charles: open an issue to ask a question, or submit a pull request to add artifacts.

x-coverage:
state: covered
reason: covered
detail: 'Charles University is one of the rare universities with a substantial institution-operated programmable footprint,
and this profile is a correction of a June 2026 one that both understated it and misbased it. Five keyless production
REST APIs run on lindat.mff.cuni.cz under UFAL in the Faculty of Mathematics and Physics (translation, UDPipe, NameTag,
MorphoDiTa, Korektor); all five were probed live and returned 200 with real payloads. Three OAI-PMH 2.0 endpoints on university-owned
hosts answered verb=Identify. The university''s own Shibboleth SAML IdP serves metadata at idp.cuni.cz. DataCite (CUNI)
and Crossref (5727, 55007) memberships were confirmed against the registries. UFAL publishes documentation rather than
machine-readable contracts for four of the five services, so those OpenAPIs are derived and marked as such; only the translation
API ships its own Swagger 2.0. What is genuinely absent: no central developer portal, no open-data portal (data.cuni.cz
and opendata.cuni.cz do not resolve), no api.cuni.cz, and no public API over the Study Information System — student-facing
systems are gated behind eduID/Shibboleth. Library discovery is an Ex Libris Primo tenancy and cuni.figshare.com is a
Figshare tenancy; both relationships are recorded and neither vendor contract is saved here. The institution''s AI posture
is published only in Czech at ai.cuni.cz. Note for pointer liveness: the four UFAL service base URLs (.../udpipe/api,
/nametag/api, /morphodita/api, /korektor/api) return 404 on a bare GET because those services expose no root resource;
every operation beneath them (/models, /process, /recognize, /tag, /correct) returned 200 when probed. They are kept because
they are the servers[] base the contracts declare. The LinkedIn page returns 999 (anti-bot) and cuni.figshare.com returns
202 (AWS WAF challenge); both are live, not dead.'
