x402-api-catalog.onrender.com

Audits another x402 service for the exact failure modes that cause aggregators (agent-tools.cloud, x402scan, Bazaar) to mark it 'down' or make its 402 challenge unreadable: missing/invalid /.well-known/x402 descriptor, an unpaid request returning 500/404 instead of a clean 402, a malformed or missing payment-required challenge, and drift between the descriptor's advertised terms and the live challenge. Returns a concrete diagnosis and fix for each failing check, not just pass/fail.
