POST /api/asn-info

live

Look up the Autonomous System (ASN), prefix, country, registry, and allocation date for an IPv4 address - or for a hostname (which is resolved first). Uses Team Cymru's free DNS-based IP→ASN mapping; no HTTPS upstream, no auth, no rate-limit headaches.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.

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.

GET https://bazaar.agentexchange.work/r/8ecb30260ee2/probe.json re-runs this probe right now for $0.01 and writes the result here.
