source: live HTTP probes of every host named in apis.yml, the OpenAPI servers[] blocks, the
  Anthem developer portal, and the first-party "Interoperability API Endpoint Support Document"
  (IO105 v15.0, effective 2025-11-18).
description: >-
  Well-known discovery documents published by Elevance Health. The registrable domains
  (elevancehealth.com, anthem.com) serve NO /.well-known documents at their roots — every
  root path 404s or is refused by the edge. The real discovery documents live where the
  FHIR/SMART specifications put them: under each FHIR base URL. Three SMART App Launch
  configurations and one full OpenID Connect discovery document were retrieved anonymously.
notes:
  - The SMART configurations are served at <fhir-base>/.well-known/smart-configuration, which
    is the location the SMART App Launch IG mandates. They are genuine documents, not SPA shells.
  - No security.txt, api-catalog, ai-plugin.json, agent-card.json or agent.json was served on
    any host. No llms.txt on any host.
  - www.elevancehealth.com answers 403 (edge bot policy) rather than 404 for the
    /.well-known/*.json paths; recorded as probed-403, not as a served document.
