POST /lookup

unprobed

Given an internet address (IP) or a network identification number (ASN), this tool returns who operates that piece of the internet: the network number, the owner's name, the country it's registered in, the regional registry that manages it, and the exact address range it belongs to.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

curl -si -X POST 'https://asn-lookup.underscoredone.com/lookup' -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.
