DNS Lookup API: Query Any Record Type as JSON

Shelling out to dig or nslookup from application code is brittle and hard to do in serverless or browser contexts.

Query any DNS record type for a domain over a plain HTTPS GET and get clean JSON back.

Look up MX records

curl -G "https://dns-lookup22.p.rapidapi.com/dns/records" \
  -d "domain=github.com" -d "type=MX" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: dns-lookup22.p.rapidapi.com"

const res = await fetch(
  "https://dns-lookup22.p.rapidapi.com/dns/records?domain=github.com&type=MX",
  { headers: {
      "X-RapidAPI-Key": "YOUR_KEY",
      "X-RapidAPI-Host": "dns-lookup22.p.rapidapi.com",
  } }
);
const records = await res.json();

Every common record type

Pass type to fetch A, AAAA, MX, TXT, NS, CNAME, or SOA records. Use it to verify email deliverability (MX plus SPF/DKIM in TXT), check domain configuration, or monitor changes.

Use cases

Validate that a customer's domain has correct MX records before enabling email, surface SPF and DMARC TXT records in an onboarding wizard, or build a lightweight DNS health check — all without running your own resolver.
