Pay-per-contract e-signature service for software and AI agents to send, sign and track legally binding documents with no subscription fees.
Overview
APISign is an e-signature service designed for software and AI agents. Users write contracts in Markdown with variables or import Word documents, fill in the variables, add signers and send them through an MCP server, REST API, CLI or web dashboard. Each signer receives an email with a private link to review and sign the document in their browser without needing an account. When all parties have signed, a final PDF with a SHA-256 completion seal is emailed to signers and the sender. Every view and signature is logged with time, IP address and device, and events can be pushed to other systems via signed webhooks.
The service is priced at $0.25 per contract sent with no monthly fee, no per-seat charge and no minimum. New accounts start with 20 free contracts. The MCP server includes twelve tools for managing templates and contracts, and the same operations are available as JSON over HTTPS through the REST API.

Q&A
- Is there a monthly fee?
- No. There are no subscriptions in APISign at all — no plans, no tiers, no minimums. You load a balance and each contract you send draws it down.
- Do I need a credit card to start?
- No. Creating an organization grants a $5.00 balance automatically, which is 20 contracts at $0.25 each. You only add a card when that runs out.
- Does a contract with several signers cost more?
- No. One send is one charge, however many people have to sign it. Providers that price per signature get more expensive as your documents get more parties; this one does not.
- Can I test without paying?
- Yes. Contracts flagged as test mode run through the full send path with no charge and no balance needed. The signing email goes to you instead of the signers, and the document carries a TEST stamp.
- Do unused funds expire?
- No. Your balance sits on your account until you spend it. There is no monthly reset and nothing to use or lose.
