x402: HTTP-Native AI Payments

2

402 Response

Profile

Payment settles, profiling begins

AI Agent pays for profiling
typescript
// Your AI agent - no API key needed
const response = await fetch('https://kaleiai.com/api/v1/profiling/run', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    agentId: 'my-autonomous-agent',

});

// Server returns 402 with payment requirements
if (response.status === 402) {
  const requirements = await response.json();
  // Sign USDC payment on Base using your wallet
  const payment = await wallet.signPayment(requirements);

  // Retry with payment signature
  const result = await fetch(requirements.resource.url, {
