  title: Amazon KMS List and Describe Keys
  summary: List the KMS keys in the account and describe the first one in detail.
  description: >-
    Provides a quick inventory-then-inspect pass over the account's KMS keys. The
    workflow lists all KMS keys in the caller's account and Region, captures the
    identifier of the first key returned, and describes that key to surface its
    full metadata. The KeyId is chained from the list response into the describe
    call. Each step spells out its request inline, including the AWS JSON protocol
    X-Amz-Target header, so the flow can be read and executed without opening the
    underlying OpenAPI description.
