Agents: call this before paying an x402 endpoint you haven't used. Pass its URL and get a verdict (ok / caution / avoid / unknown) with reasons: whether real wallets pay it, whether its popularity looks automated rather than organic, whether its price is fair versus comparable APIs that sell, and decoy, self-paid or temporary-domain red flags. Built on a continuous crawl of the whole Bazaar.
