Portal de APIs Bupa (Bupa Chile)
The Bupa Chile API portal at apidoc.bupa.cl — an Angular single-page application that ships Swagger UI and renders API definitions fetched from the backend controller at https://api.bupa.cl/portal/ms-controller. Every anonymous request to that backend returns HTTP 401, so no definition can be read without credentials. Access is fronted by Microsoft Entra ID (authority login.microsoftonline.com tenant 6faad805-0755-4412-981c-e2d4e4021ee7, client_id 744efffa-f93d-4137-b874-cef142712fa6, redirect https://apidoc.bupa.cl/public/login), whose OpenID Connect discovery document is publicly readable and is captured verbatim in well-known/. The portal is a login wall rather than a self-serve developer surface.
