Graphite Health

Graphite Health is a member-led, non-profit 501(c)(4) health-data infrastructure company founded by Intermountain Health, Presbyterian Healthcare Services and SSM Health, later joined by Kaiser Permanente and Emory Healthcare. It operates a platform that ingests, standardizes and integrates clinical data across member health systems — a connector library for clinical and external systems, a single interoperable data model, managed container runtimes, developer APIs and a data sandbox — and governs the S2 standard, an information standard encoding the operational semantics of health data whose adoption is funded by Gates Ventures. On top of the platform it runs an application marketplace whose apps must be certified under Graphite's Digital Hippocratic Oath. As of this profiling pass Graphite publishes no public developer documentation and no machine-readable contract; its FHIR, platform-core and identity hosts exist in DNS but refuse connections from the public internet.

Graphite Health is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Health Data, Interoperability, and Clinical Data.

Graphite Health’s developer surface includes support, engineering blog, and 16 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/graphitehealth: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Graphite Health markets developer APIs, an SDK and a data sandbox on /platform and /marketplace, but /developers
    is a 308 redirect to that marketing page whose only call to action is a contact form — and the three API-shaped hosts
    that do exist in DNS (fhir.graphitehealth.io, labs-core.graphitehealth.io, id.graphitehealth.io) all refuse TCP 443 from
    the public internet, so the platform is reachable only from inside member health-system networks.
