  title: Castr Analytics Live Streams API
  description: 'Castr is a live video streaming, multistreaming, and video-hosting (VOD) platform. This OpenAPI describes Castr''s documented, self-serve REST API at https://api.castr.com/v2 for managing live streams and their multistream platform destinations, sub-second (WebRTC) streams, video hosting folders and uploads, live-to-VOD recordings, activity logs/events and stream stats, and webhook endpoints. Requests are authenticated with an API token issued from the account settings API section and sent in an authorization header.


    Endpoint paths, methods, and resource groupings are taken from Castr''s published developer reference and its machine index (developers.castr.com, including llms.txt). The request/response schemas here are honestly modeled from the documentation rather than copied from a Castr-published OpenAPI file; verify property-level detail against the live reference.'
