Before paying an unknown x402 endpoint, ask for a verdict
Before paying an unknown x402 endpoint, ask for a verdict. Checks the live 402 response without paying, compares the price with its market category, shows real usage from the Coinbase Bazaar (payers, repeat buyers, last payment) and the seller's footprint, and returns ok, caution or avoid with reasons.
