Document Extraction Agent
A document extraction agent reads unstructured files — PDFs, scans, emails — and returns validated structured data.
/ quick answer
Extraction agents pair a vision-capable model with a strict output schema and a validation pass. The pattern that works in production: extract to schema, validate against business rules (totals match, dates plausible, IDs exist), and route only failures to a human. Confidence scores without validation are not enough.

What is an example of Document Extraction Agent?
Invoice extraction returning supplier, VAT ID, line items and total, then rejecting any document where line items don't sum to the total.
