Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

curl -si -X GET 'https://402utils.com/v1/x402-quote' -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.
