How this service works
Resolve DNS records for a domain via Cloudflare DNS-over-HTTPS — A, AAAA, MX, TXT, NS, CNAME, SOA. Pass name= and type= (default A). Returns each record with its TTL, plus NXDOMAIN when the name does not exist. The DNS commodity agents call constantly for infra, email and domain checks, served at the sub-cent floor. Not financial advice.
Output
Returns one or more DNS resource records matching the requested type, each including the record data (e.g. IP address, hostname, or string value) and its TTL in seconds. If the domain does not exist, returns an NXDOMAIN response. Multiple records may be returned for types like MX or NS.
Example use cases
Email deliverability verification
“Can you pull the MX and TXT records for example.com so I can check whether SPF and DKIM are properly configured for email deliverability?”
Domain existence check
“Does the domain myfancystartup.io actually exist in DNS, or does it return NXDOMAIN? Look up its A record.”
Infrastructure IP resolution
“What IP address does api.stripe.com resolve to right now? Give me the A record and its TTL.”
