Avenue3

Avenue3 Limited is a UK open data and openEHR technology consultancy headquartered at Platform, New Station Street, Leeds. Founded in November 2020 (Companies House 13040131), the firm positions itself as a trusted public sector partner delivering strategy, discovery, architecture and full-stack engineering services that separate clinical data from the applications that write it. Its practice is built around openEHR — the vendor-neutral health record standard used by NHS organisations across England, Scotland and Wales and by national programmes in Norway, Germany, Slovenia and Australia — and it is a listed openEHR Industry Partner. Avenue3 sells consulting engagements rather than a software product: it publishes no developer portal, no API documentation and no machine-readable contract of its own, and the APIs it builds are operated by its clients. Its only public technical surface is the Avenue3-dev GitHub organisation, which ships a small set of general-purpose open-source developer libraries to npm and NuGet. Avenue3 is also listed on the UK Digital Marketplace as a G-Cloud 14 supplier.

Avenue3 is profiled on the APIs.io network. Tagged areas include Company, Consulting, Healthcare, openEHR, and Open Data.

Avenue3’s developer surface includes engineering blog and 6 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/avenue3: open an issue to ask a question, or submit a pull request to add artifacts.
