aid: particle-health name: Particle Health description: 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. image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg url: https://raw.githubusercontent.com/api-evangelist/particle-health/refs/heads/main/apis.yml type: Index access: 3rd-Party position: Consumer tags: - ADT - C-CDA - Care Coordination - Carequality - Clinical Data - CommonWell - Deltas - eHealth Exchange - EHR - FHIR - Health Data - Health Information Exchange - Healthcare - HIE - HL7 - HL7v2 - Interoperability - Medical Records - Patients - Pharmacy - QHIN - Surescripts - TEFCA - USCDI created: '2026-05-24' modified: '2026-05-24' specificationVersion: '0.20' apis: - aid: particle-health:patient-data-api name: Particle Health API description: The Particle Health API is a RESTful interface for patient demographic registration, clinical data querying, and document retrieval across all major US health information networks. Developers register a patient via demographics, submit a query under a defined Purpose of Use, and asynchronously receive normalized clinical data in FHIR R4 Bundles, C-CDA documents, Flat datasets, or Deltas (incremental change sets). The API also exposes batch query, network participant search, patient provider mapping, and webhook event notifications for query completion, ADT, transitions, encounters, and AI output. Authentication uses OAuth 2 Client-Credentials grant with JWT access tokens scoped to a project. image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg humanURL: https://docs.particlehealth.com/ baseURL: https://api.particlehealth.com tags: -
