Particle Health
Particle Health is a healthcare data interoperability platform that aggregates patient medical records from across the US healthcare system into a single RESTful API. Particle is connected to all three nationwide health information exchange networks (Carequality, CommonWell, eHealth Exchange), TEFCA / QHIN partners, state HIEs (Healthix in New York, Manifest MedEx in California), and Surescripts for pharmacy data. The platform exposes patient demographics, clinical resources, and document retrieval via FHIR R4, C-CDA, Flat, and Deltas formats, layered with deduplication, normalization, AI summarization (Particle Snapshot), real-time encounter and transition alerts (Particle Signal), and longitudinal patient journey tracking (Particle Navigator). Customer segments include value-based care organizations, payers, health systems, primary and specialty providers, and digital health developers.
Particle Health publishes 17 APIs on the APIs.io network, including Authentication API, Batches API, CCDA API, and 14 more. Tagged areas include ADT, C-CDA, Care Coordination, Carequality, and Clinical Data.
The Particle Health catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Particle Health’s developer surface includes authentication, YouTube channel, documentation, API reference, sandbox, changelog, engineering blog, and 24 more developer resources.
