  title: AWS API Gateway Audit an HTTP API Surface
  summary: Confirm an HTTP API and enumerate its routes, integrations, and stages in a single read-only pass.
  description: >-
    A read-only inventory of an Amazon API Gateway V2 API. The workflow confirms
    the API exists, then lists its routes, integrations, and stages so the full
    request surface and published environments can be reviewed together. Because
    getStages collides with the V1 description it is addressed through the V2
    source. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
