Catena-X

Catena-X is the automotive industry's data space standard, published by Catena-X Automotive Network e.V. — a non-commercial German registered association founded on 15 May 2021 by BMW, Mercedes-Benz, Volkswagen, Bosch, SAP, Siemens, Schaeffler, ZF, BASF, Henkel, Deutsche Telekom and Fraunhofer, with backing from the German Federal Ministry for Economic Affairs and Climate Action. It publishes a numbered CX-xxxx library of 77 standards covering how a supply chain exchanges part data, carbon footprints, quality records, demand and capacity signals and digital product passports without any participant surrendering its data to a central platform. Standards move forward together in named releases — Jupiter, Io, Saturn, Titan — gated by a Technical Committee for Standardization, and conformance is certified by nominated third-party assessment bodies including TÜV Rheinland and TÜV SÜD. The reference implementation is open source as Eclipse Tractus-X, and the network is operated commercially by Cofinity-X. It is the most institutionally complete industry API standard in Europe, and the one whose endpoints an outside developer can never call: in a data space every participant runs its own connector and registry, so there is nothing to call until you are onboarded, credentialed and certified.

Catena-X is profiled on the APIs.io network. Tagged areas include API Standards, Asset Administration Shell, Automotive, Catena-X, and Certification.

Catena-X’s developer surface includes developer portal, documentation, product news, YouTube channel, and 27 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/catena-x: open an issue to ask a question, or submit a pull request to add artifacts.

Standards implemented 1

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.

OpenAPI

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
