How this service works

Output
Returns a JSON object containing the base64-encoded PDF of the completed NDA contract, the generated file name (e.g. mutual_nda_acme-corp_global-data.pdf), document type, and file metadata including page count, format (PDF/A-3), and language. The PDF is DocuSign-ready and generated from a deterministic legal template.
