SMART Health IT

SMART Health IT is the open standards and open source project run by the Computational Health Informatics Program at Boston Children's Hospital and Harvard Medical School that defines SMART on FHIR - the OAuth 2.0-based SMART App Launch framework that lets patient-facing and clinician-facing apps plug into any EHR and read clinical records over FHIR. The project publishes the HL7 SMART App Launch and FHIR Bulk Data specifications, the SMART Health Cards and SMART Health Links verifiable clinical data frameworks, open source client libraries, and free public sandboxes - an open FHIR R4 server loaded with synthetic patient records, the SMART App Launcher for simulating EHR and patient portal launches, and a reference Bulk Data server for testing system-level export.

SMART Health IT publishes 6 API contracts indexed on the APIs.io network, including Bulk Data API, Clinical Records API, Conformance API, and 3 more. Tagged areas include SMART on FHIR, FHIR, Health IT, EHR Integration, and Clinical Data.

The SMART Health IT catalog on APIs.io includes 1 Spectral governance ruleset.

SMART Health IT’s developer surface includes engineering blog, authentication, documentation, and 10 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
