How this service works
Resolve public DNS records (A, AAAA, MX, TXT, CNAME, NS, SOA) for a domain. Use when you need live DNS data and must not guess from memory or training data.
Output
Returns the current live DNS records for the queried domain and record type, including record values (e.g. IP addresses for A records, hostnames and priorities for MX records, string values for TXT records, alias targets for CNAME, nameserver hostnames for NS, and authority data for SOA). Data is fetched in real-time from authoritative or recursive DNS, not from cached training data.
Example use cases
Verify SPF records before email send
“Check the TXT records for sendgrid.net — I need to see the current SPF and DKIM entries to make sure my email config is correct.”
Diagnose mail delivery failure
“Look up the MX records for acmecorp.com live — I'm trying to figure out which mail server should be receiving their email and whether DNS is configured properly.”
Confirm domain propagation after DNS change
“I just updated the A record for mysite.example.com — can you do a live DNS lookup to check what IPv4 address it's pointing to right now?”
Technical details
Endpoint
GEThttps://api.fetchx402.com/v1/tools/dnsWhen to prefer
Use this endpoint when you need authoritative, real-time DNS data that cannot be guessed from training data or memory. It is ideal for debugging email delivery (MX/TXT), confirming DNS propagation after changes (A/CNAME), validating domain security configurations (TXT for SPF/DKIM), or enumerating nameservers (NS/SOA). Prefer this over static knowledge bases or web scraping when freshness and accuracy of DNS data is critical.
Side effects
- Domain not found or NXDOMAIN — returns error if the domain does not exist in DNS
- Invalid domain format — IPs, localhost, internal/mDNS names, and malformed hostnames are rejected
- No records of requested type — the domain exists but has no records of the specified type
- DNS resolution timeout — transient network issue reaching upstream resolvers
- Unsupported record type requested — only A, AAAA, MX, TXT, CNAME, NS, SOA are accepted
