SchemaLock — parse a contract for its key terms as structured JSON data from a PDF or imag
SchemaLock — parse a contract for its key terms as structured JSON data from a PDF or image (parties, dates, term, payment terms, termination clause, governing law, obligations, signatures). Unlike generic OCR or text-only extraction APIs, this takes the raw file directly and validates date logic (expiration after effective date), one automatic retry. Still fails after that, you aren't charged. Per-field confidence included.
