summary
Arc’s nano payments use HTTP 402/X2X to let AI agents sign off‑chain payments that are later batched and settled via a gateway, using ephemeral agent wallets and gateway deposits. Live demo shows an agent with a 1 USDC spending cap completing 98 tasks on 1 USDC across quotes, datasets, compute and treasure-hunt endpoints, each returning in sub-500ms per request with effectively zero gas per transaction after batch settlement.
