HealthOS exposes a unified API surface across its four architectural layers. Every capability shares the same identity layer, the same audit trail, and the same data model — so institutional integration is with HealthOS, not with a catalog of products.

one codebase
Every capability reads and writes against the same four-layer architecture above a shared data model and identity layer.
Record, encounter, orders, documentation, safety, assessment.
Beds, staffing, theaters, incidents, quality, consent, facilities.
Charge capture, revenue cycle, claims, pharmacy economics, tariffs.
Longitudinal record, portal, messaging, PROMs, family graph, recall.
Reasoning surfaces — risk, safety, prediction, model governance.
Endpoint specifications, request and response schemas, authentication flows, and event payloads are not published publicly. Technical detail is provided to certified integration partners under NDA.
Request / response for clinical, operational, and financial workflows. Every call is identity-governed, audit-logged, and reasoned upon by the Clinical Reasoning Layer where clinically relevant. Idempotent writes. Typed responses. Versioned.
Event streams and signed webhooks surface clinical, operational, and financial events in real time to institutional data platforms, SIEM, and downstream analytics. Every model-surfaced event carries its version and review trail.
FHIR R4 resources are served where the standard models the workflow — patient, encounter, observation, medication, procedure, condition, allergy, and adjacent. Domain-native surfaces cover operational, financial, and reasoning workflows where FHIR does not apply.
Per-tenant isolation at the data, identity, and compute layers. Sovereign deployments support dedicated and air-gapped configurations.
Declarative, role-governed workflows share one engine across clinical, operational, and financial domains. Role boundaries enforce institutional policy.
Every request — human, system, or AI — is authenticated, authorized, and audited against the same role-based identity layer. A model cannot see what a clinician cannot.
The Clinical Reasoning Layer observes clinical requests and surfaces safety, risk, and recommendations into the workflow. Advisory by default; clinician decides.
Clinical, operational, and financial events are durable and replayable for institutional data platforms and audit. Signed delivery. Versioned schemas.
EU, UK, US, Middle East, APAC, India. No cross-region data transfer except where explicitly authorized by the institution.
FHIR R4 where the standard models the workflow. Domain-native surfaces where it does not. No retrofit of operational and financial workflows into clinical-only standards.
Mobile-first clinical surfaces for iOS and Android. Browser-grade administration. One codebase across surfaces.

Architecture dossiers, API specifications, event schemas, security questionnaires, and sandbox access are provided to institutional buyers and certified integration partners under standard confidentiality. Technical briefings are scheduled with the Veronara architecture team on request.
Executive briefings are offered to hospital networks, ministries of health, and enterprise healthcare institutions.
