x402 seller check
● Liveloudtzu.workers.dev
Check an x402 seller before you pay it: our real paid tests (delivered or failed, quoted vs paid, worst-case prepay, latency, tx links), public paid-but-not-delivered reports, and x402scan/Bazaar signals. $0.01 here vs. risking a full call on a seller that rejects payments or doesn't deliver. Each answer states what the data cost us. Free list at /sellers; unknown sellers get a free 404.
