How you pay

Agents (x402): an unpaid call returns HTTP 402 with the exact amount. Pay in USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on eip155:8453 to 0xc22f9CAEBAc37fE72D5142f35f21f6696Ea9Ef69, scheme exact, then retry with PAYMENT-SIGNATURE.
You are charged only for successful (2xx) responses. 402, 4xx and 5xx responses are not settled. See Terms for what counts as delivered.
Humans (card, Stripe): one checkout buys one call. Card checkout charges the listed price or $0.50, whichever is higher.
The amount in the 402 challenge at call time is authoritative. Some skills price by option (the 402 shows the exact amount).
