Live health check of any x402 endpoint before you pay it
Live health check of any x402 endpoint before you pay it: is it up and answering 402, is the payment request valid, prices in USD per network, pay-to wallets, x402 version, Bazaar discovery metadata, response time, and its buyers in the Bazaar. Never pays the endpoint. Pass ?url=https://api.example.com/paid&method=GET.
