  title: CDP → Akrites External Advisories Affiliations API
  version: 0.1.0
  description: 'Read-only external API exposing CDP package security data to the Akrites service. Authenticated via Auth0 M2M client-credentials — CDP only verifies the resulting access token; the assertion exchange happens entirely between Akrites and Auth0.


    Packages, Advisories and Contacts endpoints are implemented. Blast Radius is specced separately and not yet built.


    TODO: scopes below (read:packages, read:stewardships) are the existing internal CDP UI scopes, reused here for now. Swap for a dedicated cdp:packages:read scope once Akrites gets its own Auth0 M2M scopes per the akrites-external draft contract.
