Every request below was executed against the live API on 20 Aug 2026, and the response shown is the real body it returned — not an illustration.

curl 'https://dns.google/resolve?name=example.com&type=A'

const res = await fetch("https://dns.google/resolve?name=example.com&type=A");
if (!res.ok) throw new Error(`Request failed: ${res.status}`);
const data = await res.json();
console.log(data);

import requests

res = requests.get("https://dns.google/resolve?name=example.com&type=A", timeout=20)
res.raise_for_status()
print(res.json())

Time to live in seconds.

• Build DNS lookup and diagnostic tools that run in the browser
• Verify domain configuration such as MX and SPF records
• Check DNSSEC validation status for a domain
• Monitor DNS records for unexpected changes

If Google Public DNS does not fit, these security & auth apis cover similar ground. Every one was called before publishing, and each links to its own reference page with a working curl command and the response it returned.
