Demo store · Monad testnet

A real seller, protected by Argus

This store sells a paid API over x402 and runs the argus-x402-middleware. Every wallet that pays gets a price from its verdict: a seller's promo is shared by all wallets one operator controls, so ten wallets from one funder cannot claim ten promos. Nothing on this page is mocked: quotes come from the live middleware and every claim below is a payment that settled on Monad testnet.
