An agent buys its own ERC-8004 identity on Arc with a signature alone: $0.99 over x402, paid in USDC on Arc or Base. We host a correct registration file, mint the identity and hand it to the wallet that signed the payment, never to a typed address, and answer with the agentId and both transactions. Call once without payment to get the x402 terms, sign them, call again with payment. A refused input is never charged.
