  title: Vapi Outbound Call Then Cost Analytics
  summary: Place an outbound call, poll it to completion, then query call analytics for cost and duration.
  description: >-
    The measure-what-you-ran flow. It places an outbound call using an existing
    assistant and phone number, polls the call until it ends, and then runs an
    analytics query over the call table to aggregate cost and duration for the
    reporting window. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
