notes: >-
  The BLPAPI OpenAPI projections in this repo declare no HTTP securitySchemes because BLPAPI is a
  socket/SDK API — authentication is session- and identity-based, not header-based. The derive pass
  (derive-authentication.py) therefore found 0 schemes; this profile is searched from the SDK docs
  and Bloomberg's published OAuth discovery metadata.

schemes:
  - name: DesktopAPISession
    type: session-identity
    description: >-
      Desktop API — the BLPAPI SDK connects to localhost:8194 and inherits the identity of the
      logged-in Bloomberg Professional (Terminal) user. No separate credentials are exchanged.

  - name: ServerApiAuthorization
    type: session-identity
    description: >-
      Server API (SAPI) / B-PIPE — applications authorize users and applications through the
      //blp/apiauth service (AuthorizationRequest), producing Identity objects attached to requests
      and subscriptions. The SDK models this as AuthOptions / AuthUser / Identity (see the Python SDK
      reference). Entitlements (EIDs) gate which data an identity may receive.
