Try it (unpaid: shows the 402)

curl -si -X GET 'https://x402engine.app/api/travel/hotels' -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)
