Signbee – An API that lets AI agents send documents for signature
Hi HN, I built Signbee while working on AI agents that handle contracting workflows. The agents could draft agreements, negotiate terms, manage deals — but the moment a signature was needed, the workflow broke. It always ended with "please upload this to DocuSign" — which meant human intervention, account setup, and manual uploads. So I built a simple API. You POST markdown and Signbee generates the PDF, or you pass a URL to your own PDF if you already have one designed the way you want it. No templates, no editor. Either way, it verifies both parties via email OTP and produces a signed…

What it does
Signbee is document signing built for AI agents. No accounts, no templates, no DocuSign. Tell your agent "Send an NDA to Michael" — Signbee generates the PDF from markdown, runs a two-party signing ceremony, and delivers a SHA-256 certified document to both parties. Three ways to integrate: • MCP Server (Claude, Cursor, Windsurf) • Agent Skill (any framework) • Direct API (one POST call) Free: 5 docs/month. Pro: $9 for 100. Business: $19 unlimited. Give your AI a pen.
Send, sign, and verify documents with a single API call. Two-party signing with email verification. The signing infrastructure built for autonomous agents.
Send a contract, get both signatures back. One API call. Signbee handles the rest. curl -X POST https://signb.ee /api/v1/send \ -H "Content-Type: application/json" \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "markdown": "# NDA\n\nTerms here...", "sender_name": "Alice", "sender_email": "[email protected]", "recipient_name": "Bob", "recipient_email": "[email protected]" }' RESPONSE 200 OK { "document_id" : "cmm..." , "status" : "pending_recipient" , "signing_url" : " https://signb.ee /sign/abc123" , "message" : "Document sent to Bob for signing." } Built for agents Send markdown, get a professionally rendered PDF. No templates. No configuration. Already have a document? Pass a pdf_url instead.…from signb.ee

DocEndorse2025 · docendorse.com · ▲8We built an autonomous AI agent that helps with e-signature workflows - kind of like a smart assistant you can chat or talk to. You can check out the demo here: https://youtu.be/yP19cE7s0TA You just tell the assistant (via chat or voice) what you need. It asks a few simple questions and handles the rest. Here’s what it does: • Creates e-signature requests and templates, or use templates you've created - by chatting with you — no form builders. • Auto-detects fields in your PDFs and suggests who should sign, what type of input is needed (signature, date, title, etc.) based on…

Hi HN! We're Haakam, Michael, and Adi from AgentMail- a ycs25 company. We give AI agents their own email inboxes. Recently, we ran an experiment called Agent.Email. It's a signup flow designed specifically for AI agents instead of humans. The inspiration came from a few comments we received when we did our seed launch a few months back. They all came from the very apt observation that agents not being able to sign up to a product made for agents without human credentials was ironic and unideal. This is basically the thesis we built AgentMail on: The internet was made for humans exclusively,…
