Try it (unpaid: shows the 402)

curl -si -X GET 'https://free-api-resell.relayhop.workers.dev/v1/polymarket/markets' -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.
