TypeScript SDK

The TypeScript SDK (@agent-receipts/sdk-ts) provides tools for creating, signing, and verifying Agent Receipts in Node.js and browser environments.

Repository: agent-receipts/sdk-ts

Features

• Create and sign Agent Receipts with Ed25519
• Build and verify receipt chains
• Validate receipts against the JSON Schema
• Action taxonomy helpers and risk level utilities
• TypeScript-first with full type definitions

Quick example

import { createReceipt, signReceipt, generateKeyPair } from "@agent-receipts/sdk-ts";

const keys = generateKeyPair();

const receipt = createReceipt({
  issuer: { id: "did:agent:my-agent" },
  action: {
    type: "filesystem.file.read",
    risk_level: "low",
  },
  principal: { id: "did:user:alice" },
  outcome: { status: "success" },
});

const signed = signReceipt(receipt, keys.privateKey, "did:agent:my-agent#key-1");
