x402 endpoint deep check, never pays or signs
x402 endpoint deep check, never pays or signs: the full /api/x402-check report plus live checks. GET url (optional method, body). Adds TLS, security headers, CORS, payTo vs the payee's own published addresses (/.well-known/x402, openapi.json, llms.txt), lookalike payTo detection, and drift between the live 402 and well-known, openapi and CDP Bazaar listings. Any HTTP answer from the target is billed; bad input, blocked hosts and timeouts are not.

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.
