Quick Start

Agent Mint (SIWA + x402)

// 1. Build SIWA auth
const timestamp = Math.floor(Date.now() / 1000).toString();
const message = `Sign-In With Agent: api.helixa.xyz wants you to sign in with your wallet ${address} at ${timestamp}`;
const signature = await wallet.signMessage(message);
const auth = `Bearer ${address}:${timestamp}:${signature}`;

// 2. Mint (x402Fetch handles payment automatically)
const res = await x402Fetch('https://api.helixa.xyz/api/v2/mint', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'Authorization': auth },
  body: JSON.stringify({
    name: 'MyAgent',
    framework: 'openclaw',
    personality: { quirks: 'curious', values: 'transparency' },
    narrative: { origin: 'Built to explore', mission: 'Score agents fairly' },
  }),
});
