New Toolkit Request: Signbee — Document Signing API for AI Agents

Toolkit Request: Signbee

What is Signbee?
Signbee is a document signing API built for AI agents. One API call sends a document for two-party e-signing — both parties sign, both get a SHA-256 certified PDF.

Endpoints available:

• POST /api/v1/send — Send a document for signature (markdown or PDF URL)
• POST /api/v1/generate — Generate and preview a PDF without sending
• GET /api/v1/documents/{id} — Check document status
• DELETE /api/v1/documents/{id} — Revoke a document

Auth: API Key via x-api-key header

No-auth mode: The /send endpoint also works without an API key — sender verifies via email OTP instead.

OpenAPI 3.0 spec: https://signb.ee/openapi.json

Quick test (no signup needed):

curl -X POST https://signb.ee/api/v1/send \
  -H "Content-Type: application/json" \
  -d '{"markdown": "# NDA\n\nTerms...", "sender_name": "Alice", "sender_email": "alice@co.com", "recipient_name": "Bob", "recipient_email": "bob@acme.com"}'

Why this would be valuable for Composio users:

• Every AI sales agent, autonomous business, or multi-agent team needs a way to close deals with signatures
• Zero-setup signing — no OAuth, no templates, no account required for basic usage
• MCP server also available on npm (signbee-mcp)
• Already live: https://signb.ee
• Contact: hello@signb.ee

Happy to provide any additional info needed!
