Document Validator – Required Fields & Source Evidence Checker

Choose this endpoint when you need to gate downstream automation on document completeness — specifically when you need to verify that invoices, contracts, tenders, or other text documents contain all required fields AND that those fields are backed by source evidence. Prefer this over generic extraction endpoints when validation and compliance checking (not just extraction) is the goal, and when you need a structured pass/fail result before triggering payment or workflow automation.

• Document text is empty or unparseable — returns error indicating no content to validate
• Unrecognized document type or profile — returns error with supported document types
• Required field list not provided or malformed — validation cannot proceed
• Document too large — may return a payload size error
• Network or Lambda cold-start timeout on large documents
