  title: X Fetch a List's Details and Its Members
  summary: Read a List by id, then page the members of that List.
  description: >-
    Retrieves the metadata for a single X List and then pulls the first page of
    member accounts on that List. The detail step inlines its list.fields and
    the members step inlines its user.fields and max_results so the flow reads
    and executes without opening the underlying OpenAPI description.
