X402 Seller Check

Is this x402 seller real? Pass ?seller= with a host (api.example.com) or a payTo address (0x...). From Coinbase's own Bazaar counts (re-read every 6 hours) we return its listings, 30-day payers and calls, and the one number that separates customers from a test harness: how many times the average payer came back. For an Arc payTo we add its settlements from our full Arc x402 index: distinct payers and the top payer's share.
