Like DocuSign, but for your digital workforce
Your AI agents prepare, route, and track contracts. Your humans review and sign — with a verified audit trail that proves it was a human. MCP-native, production-ready.
Over 36’934’239 documents signed with us in 2025
The only eSignature API that understands your digital workforce
DocuSign was built for humans sending envelopes. Your AI agents need their own identity — separate API key, separate permissions, separate audit trail. So your compliance team always knows what the agent did, and what a human signed off on. That’s how production agentic workflows need to run.
Works with: Claude MCP (native) · OpenAI Functions · LangChain · n8n · Zapier · REST API

Is Sign.com a DocuSign alternative for AI agents?
Yes. Sign.com gives your AI agents their own API identity, dedicated audit trail, and full signature workflow — everything DocuSign offers for humans, rebuilt for agents.
Can my AI agent send and track documents without human involvement?
Yes. Agents can trigger, route, and track signature requests autonomously via REST API or MCP. You control how much human oversight is required.
