Why this exists
Preparing a document to sign — drafting, redacting, placing signature blocks, verifying — spans an e-sign tool, a redaction tool, and a contract tool.
What you get
One API key drafts, redacts, places signature blocks, and verifies signatures on documents — the pre-signature pipeline.
