x402 seller verdict

x402 seller verdict: who paid an x402 API in the last seven days, from signed USDC payments into its wallet on Base. Returns a grade, payments, payers, repeat payers with no flag, the share from campaign wallets, crawlers and wallets the seller funded, its ten largest payers and its rank among Coinbase Bazaar sellers. Required: one of endpoint, host or wallet. $0.02 USDC on Base. Seller not in the ledger, no charge. No account, no API key. Transfer counts, not a safety finding.
