Service Base URL Publication

The FHIR service base URLs (endpoints) for all Retinex Health IT Modules certified to §170.315(g)(10) that patients can use to access their electronic health information.

Version 1.0 Updated 2026-06-03 Publicly accessible · Machine-readable · No charge
Requirement. Under §170.404(b)(2), a Certified API Developer must publish the service base URLs (FHIR endpoints) for all Health IT Modules certified to §170.315(g)(10) that patients can use to access their EHI — for all customers, whether centrally managed or locally deployed — in a machine-readable format at no charge.

1. Machine-Readable Endpoint File

The authoritative, machine-readable list is published as an HL7® FHIR® R4 Bundle of Endpoint and Organization resources at a stable, public, no-charge URL:

https://retinex.ai/docs/service-base-urls.json

Open the machine-readable Endpoint Bundle →

2. Service Base URL(s)

Retinex Health IT Modules are centrally managed by Retinex, Inc.; a single multi-tenant FHIR service base URL serves all customers:

OrganizationFHIR VersionService Base URL
Retinex, Inc. (all customers)R4 (4.0.1)https://retinex-apim.azure-api.net/smart

Because Retinex centrally manages all §170.315(g)(10) modules, customers are tenants of this single service base URL rather than separate locally-deployed endpoints. Should any customer be locally deployed in the future, its service base URL will be added to the machine-readable file above.

3. Endpoint Resource Format

Each endpoint follows the HL7 FHIR Endpoint resource (as recommended in the §170.404 Application Programming Interfaces CCG):

{
  "resourceType": "Endpoint",
  "id": "retinex-smart-r4",
  "status": "active",
  "connectionType": {
    "system": "http://terminology.hl7.org/CodeSystem/endpoint-connection-type",
    "code": "hl7-fhir-rest"
  },
  "name": "Retinex Health — FHIR R4 Patient Access API (g)(10)",
  "managingOrganization": { "reference": "Organization/retinex-inc", "display": "Retinex, Inc." },
  "payloadType": [{ "coding": [{ "code": "any" }] }],
  "payloadMimeType": ["application/fhir+json"],
  "address": "https://retinex-apim.azure-api.net/smart"
}

4. Discovery from the Base URL

From the service base URL, applications discover authorization and capabilities:

  • GET https://retinex-apim.azure-api.net/smart/.well-known/smart-configuration — SMART/OAuth endpoints (see SMART Authorization).
  • GET https://retinex-apim.azure-api.net/smart/metadata — FHIR CapabilityStatement.

5. Terms of Access

  • The endpoint file is published at no charge and requires no authentication to read.
  • It is updated whenever a service base URL is added, changed, or retired.
  • This satisfies the requirement that service base URLs be published by December 31, 2024 in a standardized, machine-readable FHIR format for all §170.315(g)(10) Health IT Modules.
