  title: Amazon EBS Snapshot and Verify Volume
  summary: Take a snapshot of an EBS volume and confirm the snapshot is visible.
  description: >-
    The requested ListSnapshotBlocks / GetSnapshotBlock direct block APIs were
    not present in the spec, so this workflow adapts the requested
    create-then-verify pattern to the EC2-style snapshot operations the
    description actually supports. It creates a snapshot of the supplied volume
    and then reads the account snapshots back to confirm the snapshot is
    available. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
