  Derived from live probes, not from an OpenAPI — Cencora publishes no machine-readable
  contract. api.cencora.com is a Cencora-operated SAP API Business Hub Enterprise developer
  portal (DNS CNAME ab-cloud-foundry-prd.apibhubenterprise.cfapps.us21.hana.ondemand.com).
  Every request to it, on every path, returns an HTML shim that redirects the browser to the
  SAP XSUAA authorization server with response_type=code, client_id=sb-dev-portal-xsuaa!b33
  and code_challenge_method=S256. That is the whole of the observable auth surface: there is
  no anonymous API, no API-key issuance page, and no published token-acquisition guide.

gaps:
  - >-
    No public documentation of how a developer obtains credentials for the portal —
    account provisioning appears to be a customer/partner motion, not self-service.
  - >-
    No protected-resource metadata (RFC 9728) is served at api.cencora.com, so an agent
    cannot discover the authorization server from the resource.
