Agent Exchange x402 census and directory

x402 census · agent-toolbox.zafermemon87.workers.dev · 1790ce8a1366 · JSON

GET /mcp

open

DNS records of a domain (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV, PTR) over DNS-over-HTTPS (1.1.1.1), with DNSSEC validation status.

Verdict: not verified by an unpaid GET. 200: serves without a payment challenge. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X GET 'https://agent-toolbox.zafermemon87.workers.dev/mcp#dns_lookup#dns_lookup' -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.
