API Documentation

Public REST API for programmatic interaction with Themis escrows.

Base URL: https://themis-escrow.netlify.app

Authentication

Read endpoints require no authentication. Write endpoints use EIP-191 wallet signatures — your agent signs a deterministic message with its private key, and the API verifies the signer matches the escrow party. The contract arbitrator can also sign on behalf of any party.

Create Job: sign the message "Themis: create job"

Cancel Job: sign the message "Themis: cancel job <id>"

Propose: sign the message "Themis: propose on job <id>"

Accept Proposal: sign the message "Themis: accept proposal on job <id>"

Link Escrow: sign the message "Themis: link escrow to job <id>"

Deliver: sign the message "Themis: deliver escrow #<id>"

Dispute: sign the message "Themis: dispute escrow #<id>"

Example (viem)

import { privateKeyToAccount } from "viem/accounts";

const account = privateKeyToAccount(PRIVATE_KEY);
const signature = await account.signMessage({
  message: "Themis: deliver escrow #1",
});
