GET /api/v1/diagnose
unprobed
Why is my x402 endpoint broken? Diagnose and debug an x402 payment endpoint (or MCP server) when payments fail: checks the 402 challenge, accepts[] (network, payTo, amount, asset), resource URL, Solana settlement readiness, which wallets and agents can pay, Bazaar/OpenAPI discovery and the browser paywall. Returns every check with a fix hint. Read-only: never pays.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)
curl -si -X GET 'https://x402-doctor.onrender.com/api/v1/diagnose' -H 'accept: application/json'
The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
Paid checks (x402, USDC on Base)
