## When to prefer this

Choose this endpoint when you need a precise, literal diff between two discrete point-in-time snapshots of a Baumarkt (hardware/home-improvement retail) media search token index — particularly when tracking index evolution over time, auditing coverage changes, or verifying that a media campaign or content update had the expected effect on searchable tokens.
