Cadasto B.V. is a Dutch health-IT company (Alkmaar, Netherlands) that builds a vendor-neutral Clinical Data Repository on the openEHR standard. The Cadasto CDR stores structured care data as openEHR compositions and exposes the openEHR ITS-REST 1.0.3 API surface — EHR, Query (AQL), Definition, Demographic, Admin and System — plus a Cadasto-specific Additional API for Datamap (a simplified JSON projection of openEHR paths), episodes of care and terminology helpers, a bidirectional FHIR R3 facade, and SMART-on-openEHR app launch. Access is OAuth 2.0 client-credentials per tenant. Cadasto also publishes an unusually strong agent surface for its size: a live anonymous MCP server for openEHR modelling knowledge, eight packaged Agent Skills, a Claude Code plugin marketplace, an llms.txt, and a public openEHR conformance statement naming every specification version it does and does not implement.
Cadasto publishes 8 APIs on the APIs.io network, including EHR API, Query API (AQL), Definition API, and 5 more. Tagged areas include Healthcare, Health IT, openEHR, Electronic Health Records, and Clinical Data Repository.
Cadasto’s developer surface includes documentation, API reference, getting-started guide, authentication, FAQ, support, engineering blog, and 30 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Health 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.
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/cadasto: open an issue to ask a question, or submit a pull request to add artifacts.
