Everything a machine buyer needs is machine-readable. Point your agent at the buying guide and it can purchase on its own.

2

Hit an endpoint

Unpaid calls return 402 with the amount, recipient wallet, and network. Your x402 client handles the rest.

3

Pay & retry

Sign the USDC transfer on Base, resend with the payment proof, get 200 with your data.
