Word-Level Bounding Boxes - Pulse API

Standard extraction returns block-level bounding boxes for text, tables, and figures. Turn on word-level bounding boxes when you need exact word coordinates for review overlays, field-level QA, redaction previews, evidence packs, or high-trust citation UX. Platform sample: Bank Statement

}

Word-level output is returned at extensions.altOutputs.wlbb. It is PDF-only and can make results much larger, so enable it for review and QA workflows rather than every ingestion job.

For most review workflows, the standard bounding box layer is enough:
