openapi: 3.1.0 info: title: Particle Health Authentication NetworkParticipants API description: Particle Health is a healthcare data interoperability API that aggregates patient medical records from US health information exchanges (Carequality, CommonWell, eHealth Exchange), TEFCA / QHIN partners, state HIEs, and Surescripts. The API surfaces patient registration, asynchronous query orchestration, batch processing, document handling, network participant directory search, patient provider mapping, and real-time Signal alerting. Clinical data is returned in FHIR R4 Bundles, C-CDA documents, Flat datasets, or Deltas (incremental changes). Authentication uses OAuth 2 client-credentials with JWT bearer tokens scoped to a project. version: v1 contact: name: Particle Health Support email: support@particlehealth.com url: https://particlehealth.com/contact license: name: Particle Health Terms of Service url: https://particlehealth.com/ servers: - url: https://api.particlehealth.com description: Particle Health Production security: - bearerAuth: [] tags: - name: NetworkParticipants description: Directory search over connected network organizations. paths: /api/v1/networkparticipants: get: operationId: searchNetworkParticipants summary: Search Network Participants description: Search for healthcare organizations participating in Particle's connected networks. tags: - NetworkParticipants responses: '200': description: Participant list /api/v1/networkparticipants/state/{state}: get: operationId: searchNetworkParticipantsByState summary: Search Network Participants by State tags: - NetworkParticipants parameters: - name: state in: path required: true schema: type: string responses: '200': description: Participant list /api/v1/networkparticipants/zipcode/{zip}: get: operationId: searchNetworkParticipantsByZipcode summary: Search Network Participants by Zipcode tags: - NetworkParticipants parameters: - name: zip in: path required: true schema: type: string responses: '200': description: Participant list components: securitySchemes: bearerAuth: type: http scheme: bearer bearerFormat: JWT description: OAuth 2 client-credentials JWT issued by `/auth`.
