University of Tübingen
The University of Tübingen (Eberhard Karls Universität Tübingen), founded in 1477, is one of Germany's oldest public research universities and a member of the German Universities Excellence Initiative, with roughly 27,000 students in Baden-Württemberg. It runs no developer portal, publishes no OpenAPI and issues no API keys, and this profile does not pretend otherwise. What it does operate, on its own uni-tuebingen.de hosts, are four genuinely institution-run machine surfaces: the FDAT research data repository (InvenioRDM, Digital Humanities Center) exposing a keyless JSON REST API with IIIF manifests and DataCite DOIs; an OAI-PMH 2.0 provider on the same host; a second, much older OAI-PMH provider for the University Library's TOBIAS-lib publication server (DSpace, records back to 1998, xMetaDissPlus); and a Shibboleth SAML 2.0 identity provider registered in DFN-AAI since 2009 and exported to eduGAIN, asserting REFEDS Research & Scholarship and SIRTFI/SIRTFI2. Its DataCite membership is verifiable — member AWZY "IKM Universität Tübingen", repository client AWZY.FEDNNV, DOI prefix 10.57754 — as is its ROR record 03a1kwz48. The University Library additionally builds and operates TueFind, its own VuFind derivative, in the open on GitHub, and runs three national subject discovery services on it (ixTheo, RelBib, KrimDok), currently behind a proof-of-work browser challenge. Campus management (alma), the VLE and the licensed library estate sit behind SSO and are not publicly documented APIs. No InvenioRDM, DSpace or VuFind product contract is saved under this institution — those belong to their upstream projects.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles University of Tübingen the way a machine reads it — 14 machine-readable artifacts across 8 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — University of Tübingen scores 39.3/100 (developing), with a separate agent-readiness read of 5/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile University of Tübingen
Each block below is one kind of artifact we hold for University of Tübingen. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 8
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
University Of Tubingen Rate Limits
RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.
Cost, billing, and metering signals for API financial operations.
Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.
JSON-LD contexts and semantic vocabularies used across these APIs.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of University of Tübingen, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
