  title: Oracle Cloud Share Object Via Preauthenticated Request
  summary: Resolve the namespace, confirm an object exists, then mint a read-only pre-authenticated URL.
  description: >-
    Generates a time-limited shareable link for an object in Object Storage. The
    workflow resolves the namespace, confirms the target object exists in the
    bucket, and creates a read-only pre-authenticated request whose access URI
    can be embedded in a download URL. Every step spells out its request inline
    so the sharing flow can be read and executed without opening the underlying
    OpenAPI description.
