  title: Beam Task Queues Web Endpoints API
  description: 'Specification of the documented Beam (beam.cloud) HTTP surfaces: synchronous invocation of deployed web endpoints, asynchronous task submission to deployed task queues, and the control-plane Tasks API for querying status and cancelling tasks. Beam deployments are created from Python with the Beam SDK/CLI; this spec covers the resulting HTTP invocation and management patterns only.'
