  title: Livepeer Secure a Stream with a Signing Key
  summary: Create a signing key, create a JWT-gated stream, and resolve playback.
  description: >-
    Sets up access-controlled playback for a livestream. It creates an access
    control signing key (the private key is only returned on creation, so it is
    captured here), creates a stream whose playback policy requires JWT
    authorization, and resolves the stream's playback info so the caller can
    confirm the gated playback sources. Every step spells out its request inline
    so the flow can be read and executed without opening the underlying OpenAPI
    description.
