description: 'Oracle Health, formerly Cerner, builds and operates Millennium — one of the two dominant electronic health record
  platforms in United States hospitals and health systems. Cerner was acquired by Oracle in June 2022 and its developer program
  now runs as the Oracle Health Developer Program. The public developer surface is HL7 FHIR R4: a multi-tenant, US Core-conformant
  FHIR server that serves a live CapabilityStatement at /metadata and a live SMART on FHIR discovery document at /.well-known/smart-configuration,
  advertising 303 OAuth scopes across patient, user and system personas in both SMART v1 and SMART v2 granular forms. It supports
  SMART App Launch (EHR and standalone), SMART Backend Services with private_key_jwt, FHIR Bulk Data Access export, and —
  unusually — an open, unauthenticated, read-only endpoint that serves real sandbox data with no registration at all. Alongside
  FHIR it operates proprietary Millennium EHR APIs, HL7 v2 messaging through Cerner Open Interface, and the CareAware device
  and integration platform. There is no OpenAPI, no GraphQL endpoint, no MCP server, no agent card, no published pricing,
  no published rate limits, no status page and no first-party SDK for the FHIR API.'
