Particle Health

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.

    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.
