  title: Amazon SageMaker Audit Endpoint Fleet
  summary: List hosted endpoints and describe the most recently created one in detail.
  description: >-
    An operations and monitoring flow. The workflow lists the account's hosted
    endpoints sorted by creation time, branches on whether any exist, and when
    there is at least one describes the newest endpoint to surface its status,
    production variants, and any failure reason. Each step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
