Rhapsody Health Solutions is a US-headquartered (Boston, Massachusetts) healthcare interoperability company trusted by more than 1,900 healthcare organizations across 31 countries, and recognized as Best in KLAS for integration engines for 17 consecutive years. Formed from the lineage of Orion Health's Rhapsody Integration Engine (2000), the 2019 merger with Corepoint Health, and acquisitions of Datica, NextGate EMPI, and CareCom, Rhapsody delivers a single interoperability platform spanning integration engines (Rhapsody and Corepoint), enterprise master patient index (EMPI / Rhapsody Identity), semantic terminology management, data governance (Guardian), and automated integrations (Envoy, Image Director). The platform supports FHIR, HL7 v2, REST, CDA, X12/EDI, SQL, DICOM, AMQP, and Model Context Protocol (MCP) from a single deployment, with embedded AI (Rhapsody Axon). Its home market is the United States, aligned to ONC/CMS interoperability mandates. Rhapsody added Guardian, a healthcare-purpose-built API gateway (OAuth 2.0, SMART on FHIR, Basic Auth), in October 2025. Rhapsody's product REST/administration and FHIR APIs are documented in a developer documentation portal (docs.rhapsody.health) that sits behind an AWS Cognito single-sign-on gate; there is no public self-serve API host or downloadable specification. The one machine-readable document Rhapsody does publish is an authoritative llms.txt at rhapsody.health/llms.txt.
Rhapsody is listed with 6 APIs on the APIs.io network. Tagged areas include Healthcare, United States, Interoperability, Integration Engine, and FHIR.
Rhapsody’s developer surface includes engineering blog, authentication, changelog, documentation, support, 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.
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/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
11 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
