Try it (unpaid: shows the 402)

curl -si -X POST 'https://agent-format.annushka1190.workers.dev/v1/base64' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. 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.
