  title: Nanonets Sync Predict and Review
  summary: Run a sync OCR prediction on a small file, then approve or hold it for review.
  description: >-
    A human-in-the-loop extraction flow for files of three pages or fewer. The
    workflow runs a synchronous OCR prediction on an uploaded file, then branches
    on the returned page: when a prediction is present it marks the file approved
    (moderated), and when no prediction came back it leaves the file unapproved
    for manual review. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
