How this service works
A, AAAA, NS, MX, TXT and CAA records of a domain in one call, with TTLs and whether it exists.
Output
Returns a structured object containing all major DNS record types (A, AAAA, NS, MX, TXT, CAA) with values and TTLs, a boolean indicating whether the domain exists, a verdict and summary string, a timestamp (asOf), source information, and optional flags for degraded lookups or unchecked record types.
Example use cases
Pre-deployment domain verification
“Before we go live, can you check all the DNS records for myapp.io — I want to see the A records, nameservers, MX, TXT, and CAA records, plus confirm the domain actually resolves?”
Investigating email deliverability issues
“We're having trouble with email delivery — can you look up all DNS records for ourfirm.com so I can see the MX records, TXT records like SPF, and whether the domain exists in DNS?”
Auditing a newly acquired domain
“I just acquired the domain legacybrand.net — can you fetch all its current DNS records including A, AAAA, NS, MX, TXT, and CAA entries with their TTLs so I know what's configured?”
Technical details
Endpoint
GEThttps://domain-dns.x402tookit.com/dns-records?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call snapshot of all major DNS record types for a domain, including TTLs and existence confirmation. It is ideal over record-type-specific endpoints when you want a full DNS audit in one request, or when you don't know in advance which record types are present. Use sibling endpoints (e.g. MX-only, DNSSEC, CAA) when you need deeper analysis of a specific record type.
Side effects
- Domain does not exist — exists field returns false with reasons
- DNS lookup partially fails — degraded flag set to true, notChecked lists missing record types
- Invalid domain name format — likely a 4xx client error
- Upstream DNS resolver unavailable — possible 5xx or timeout
- No records of a specific type — array returns null or empty for that record type
