Description
Legacy e-signature tools were built for a human clicking through a portal. But SumoSign is an API your agent calls directly. It requests, routes, signs, and returns evidence — no human in the loop. No bloat from a tool that predates AI. Explore the API today!

Could you build this?
Partial An API for issuing signature envelopes is standard CRUD and PDF overlaying, but building a legally binding, audit-ready e-signature platform requires strict cryptographic signing standards and regulatory compliance.
What it would actually take: The stack would combine a REST/MCP server (Node.js/Go) with PDF manipulation engines (PDF-lib/MuPDF) and Hardware Security Modules (HSM) or AWS KMS for X.509 cryptographic digital signatures. The hard part is ensuring non-repudiation, tamper-evident SHA-256 hash chains, and adhering to legal evidence standards like US ESIGN and EU eIDAS requirements.
