  title: Vantage Fetch Costs for an Existing Cost Report
  summary: List existing Cost Reports and pull cost data for the first one, branching when none exist.
  description: >-
    A Vantage read-only analysis pattern for working with reports that already
    exist. The workflow lists the Cost Reports the token can access and branches:
    when at least one report is present it retrieves that report's cost line
    items for a date range, and when none are present it ends without attempting
    a costs call. Every step spells out its request inline — including the Bearer
    token — so the flow can be read and executed without opening the underlying
    OpenAPI description.
