  title: Amberflo Discover Meter and Query Usage
  summary: List meter definitions then query aggregated usage for a selected meter.
  description: >-
    A reporting flow that discovers the configured meters and then reads usage
    against one of them. It lists all meter definitions, confirms the requested
    meter is present, and queries aggregated usage for it over a time window.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
