x402 Merchant Audit
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.
