  title: TikTok Research Pinned Video Comments
  summary: Resolve a handle, fetch the user's pinned videos, then pull comments on the first pinned video.
  description: >-
    Inspects the conversation around a creator's highlighted content using the
    Research API. The workflow resolves a handle to its public profile, lists
    the videos the user has pinned to the top of their profile, and then, when a
    pinned video exists, retrieves the full comment thread on the first pinned
    video. This surfaces the discussion attached to the content a creator most
    wants seen. Every step spells out its request inline, including the inline
    Bearer authorization, so the flow can be read and executed without opening
    the underlying OpenAPI description.
