Is this merchant safe to depend on?
Is this merchant safe to depend on? Audits up to ten x402 endpoints in one call and returns a verdict — ready, partially ready or not ready — with the specific blockers. Checks each endpoint serves a payable challenge with well-formed terms and a declared input schema, and adds the cross-endpoint check no single probe can make: whether every endpoint pays the same recipient. Never pays anything.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
