DNS lookup: records of a domain

$0.002 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

DNS lookup of a domain: A, AAAA, MX, TXT, CNAME, NS, CAA, SOA and other records through Cloudflare DNS over HTTPS, with TTLs, the response code and DNSSEC validation. Use to check where a domain points, its mail servers or a TXT verification record.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/dns/records?name=example.com"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/dns/records?name=example.com&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "name": "example.com",
  "type": "MX",
  "status": "NOERROR",
  "dnssec": true,
  "answers": [
    {
      "data": "0 .",
      "ttl": 86400
    }
  ],
  "resolver": "Cloudflare"
}
