notes: >-
  All HTTP (historical/reference) requests authenticate with HTTP Basic: the
  Databento API key (32 characters, prefixed db-) is the username and the
  password is left empty. API keys are created and rotated in the user portal.
  The Live Streaming API (raw TCP, DBN protocol) does not use HTTP Basic;
  sessions authenticate with a CRAM challenge-response handshake using the same
  API key (docs: https://databento.com/docs/api-reference-live/basics/authentication).
  The OAuth2 password flow below (tokenUrl /v0/auth/login) is the portal's own
  cookie/session login exposed in the platform OpenAPI, not a public OAuth
  surface for API consumers - it defines no scopes.
