description: Zus Health is a next-generation shared health data platform that brings information speed to healthcare. Its
  flagship Zus Aggregated Profile (ZAP) consolidates a patient's longitudinal medical record — encounters, conditions, medications,
  labs, and transitions of care sourced from EHR, pharmacy, ADT, and lab networks plus TEFCA — into a single, deduplicated,
  FHIR R4-native view accessible via a standalone app, embeddable UI, or API. Zus exposes a FHIR R4 REST API and a read-only
  FHIR GraphQL Query Service (FQS) over 128 FHIR resource types, an Auth Service for machine-to-machine and user authentication,
  Patient History APIs for network enrollment and querying, Zushooks event webhooks, and SQL-friendly relational data marts
  on Snowflake and Databricks. The platform is SOC 2 Type 2 compliant and HIPAA-compliant.
