HTTP 402 Payment Required

The Internet's Missing Payment Layer

x402 is the standard for machine-to-machine payments. AI agents discover payment requirements via /.well-known/x402, pay automatically, and access resources without human intervention.

1
Discover Agent fetches /.well-known/x402 to learn payment requirements
2
Pay Send PathUSD or USDC.e to the recipient address on Tempo
3
Verify POST /verify-payment with txHash to activate credits
4
Query Use X-Wallet header to authenticate all requests

x402-flow.ts

// 1. Discover payment requirements
const info = await fetch('https://api.paymetrics.xyz/.well-known/x402')

// 2. Send payment on Tempo chain
const tx = await pathUSD.transfer(
  '0x9B374...1cee4a',
  parseUnits('1', 6)  // 1 PathUSD
)

// 3. Verify payment
await fetch('https://api.paymetrics.xyz/verify-payment', {
  method: 'POST',
  body: JSON.stringify({ txHash: tx.hash })
})

// 4. Query with wallet auth
const data = await fetch('https://api.paymetrics.xyz/graphql', {
  method: 'POST',
  headers: { 
    'X-Wallet': myAddress,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    query: `{ tokens { symbol totalVolume } }`
  })
})
