Due-diligence lookup on an x402 seller before paying it
Due-diligence lookup on an x402 seller before paying it: checks that the seller's x402 endpoint answers 402 with a matching Base USDC payTo, and returns the payout wallet's funder and age, Bot Bazaar reputation, count of distinct on-chain payers, and an OFAC SDN address screen. Query by payTo wallet or endpoint URL.
