Verify an x402 seller before you pay it — a seller audit on chain: incoming USDC transfers for any Base address you name, with distinct paying addresses, repeat-payer concentration, treasury-sized flows separated out and the read's own coverage stated. This answers the question an agent has immediately before paying an unfamiliar x402 seller.
