    to Comcast partner APIs such as the Open Ingest service. Clients exchange an x-client-id and x-client-secret pair for
    an OAuth-style access token valid for 24 hours, which is then attached to subsequent requests in the Authorization header.
  x-features:
  - Client-credential token exchange
  - 24-hour bearer token lifetime
  - x-client-id / x-client-secret request headers

    outcome status.
  x-features:
  - XML asset and metadata submission
  - Bearer-token authentication via Comcast SAT
  - Partner-scoped ingestion (e.g. globalott)
  - OpenIngestResult outcome reporting
