Which x402 sellers actually earn? The top Bazaar sellers on Base ranked by measured revenue or paying wallets: 24-hour and 7-day revenue, payments, unique payers, repeat and returning payer share, top payer share, price range, categories and a likely-wash flag (one wallet doing the volume). Measured from USDC transfers of $5 or less into each seller's payTo on Base, one UTC day at a time, with the day it covers. Errors return 4xx/5xx JSON and aren't charged.
