  title: TikTok Research Video Search and Comments
  summary: Search public videos by keyword and date range, then pull comments on the first matching video.
  description: >-
    Powers an academic research flow using the TikTok Research API. The workflow
    runs a boolean keyword search constrained by region and a date range, and
    then, when at least one video matches, retrieves the full comment thread on
    the first result including comment text, like counts, and reply counts.
    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.
