SDK Playground

Write code and run it against the live API. Proof-of-work handles payment automatically. Based on agent402-client.

Code

// Hash text with SHA-256
const result = await callTool("hash", {
  text: "hello world",
  algo: "sha256"
});
console.log(result);

Output

Click Run to execute

How it works: The playground uses callTool(slug, params) which fetches a PoW challenge, solves it in your browser, then calls the tool. This mirrors what agent402-client does in Node.js. For production use, install the SDK: npm install agent402-client. Quickstart guide →
