x402 Preflight

preflight.kagurazaka.dev · x402

Check an x402 seller before you pay it. Probes the endpoint now, checks that its payment can actually succeed (token EIP-712 domain, payTo), and adds its 30-day uptime from our monitor of paid Bazaar listings, how many distinct buyers paid it, and how its price compares with similar listings, with cheaper well-used alternatives. Returns a verdict (ok, caution, avoid) with the reasons.

x402: an unpaid request gets a 402 with the price and pay-to wallet. addrbook never pays.
