Arc X402 API
Every signed x402-style payment on Arc since launch, read from the chain (plain USDC transfers carry no marker of what they paid for and are not counted): each EIP-3009 authorization spent on Arc USDC (AuthorizationUsed on 0x3600..., joined to the transfer it moved, in either of the two forms Arc logs it) and every Circle Gateway batch (net flows per address, decoded from submitBatch).
