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.\n\nContact Support:\n Name: Particle Health Support\n Email: support@particlehealth.com", "schema":
