Carefluence

Carefluence is a US health-IT interoperability vendor whose product is an ONC-certified, FHIR-based Open API platform that EHR, telehealth, remote patient monitoring, HIE and health-analytics vendors license to reach regulatory compliance and to exchange clinical data with other systems. The Carefluence Open API R4 was certified on 2022-06-29 under CHPL ID 15.04.04.2657.Care.R4.01.0.220629 against ONC criteria 170.315 (d)(1,3,9-10,12-13) and (g)(4-7,9-10), including the § 170.315(g)(10) Standardized API for Patient and Population Services; the company states it was the first FHIR-based Open API product to earn ONC 2015 Edition certification, in July 2016, and was an early participant in the Argonaut Project. The platform is a FHIR R4 server (US Core IG v3.1.1, 24 resource types) fronted by a first-party SMART on FHIR OAuth 2.0 / OpenID Connect authorization server, with a data translator for HL7 v2 and C-CDA normalization, adapters for non-FHIR back ends, a built-in integration engine, an asynchronous FHIRops product, and an announced Model Context Protocol server for AI agents.

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.

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/carefluence: open an issue to ask a question, or submit a pull request to add artifacts.
