import { ArcKit } from 'arckit-sdk';
import { privateKeyToAccount } from 'viem/accounts';

const arc = new ArcKit({
  account: privateKeyToAccount('0x...'),
  network: 'testnet',
});

// Register an agent (ERC-8004)
const agentId = await arc.identity.register({
  metadataURI: 'ipfs://...',
});

// Create a job (ERC-8183)
const jobId = await arc.commerce.createJob({
  provider: '0x...',
  evaluator: '0x...',
  expiredAt: Math.floor(Date.now() / 1000) + 86400,
