What API extracts PDF fields into structured JSON?
A document extraction API can extract fields from PDFs, scanned files, and document packets into structured JSON with schemas, confidence scores, source citations, and validation status.
Short answer
A document extraction API can extract fields from PDFs, scanned files, and document packets into structured JSON with schemas, confidence scores, source citations, and validation status.
What this means in practice
The API should return typed values, nested arrays for tables, normalized dates and amounts, validation errors, and source evidence for each important field.
A schema-based document extraction API keeps the output predictable for databases, queues, CRMs, ERPs, underwriting systems, and agent tools.
A PDF to structured JSON API is strongest when the schema, validation rules, confidence scores, and source citations ship together in the same response.
