How this service works
DNS records of a domain with TTL: A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, HTTPS. Choose the types or get the common ones at once.
Output
A JSON object containing the queried domain name, a note explaining null vs empty array semantics, and a records object with arrays of DNS entries keyed by record type (e.g. A, MX, NS). Each entry includes the TTL (time-to-live in seconds) and the record value as a string.
Example use cases
Verify email domain MX setup
“Check the MX records for acmecorp.com so I can confirm their email is routing correctly before I send a campaign.”
Debug site not loading
“Look up the A records for mystartup.io — I want to see what IP address it resolves to and confirm it's pointed at our server.”
Audit nameserver configuration
“Can you pull the NS records for example.net? I need to verify which nameservers are authoritative for the domain.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/dns-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic DNS resolution without running your own resolver, especially in agent workflows that require verifying domain configuration, diagnosing connectivity issues, or enriching domain data. It pays per call in USDC via x402, making it suitable for low-volume or on-demand lookups without a subscription commitment.
Side effects
- DNS server timeout: the 'ttl' and 'value' fields may be null if the DNS server did not respond in time
- Empty record array: if no records of a requested type exist, an empty array [] is returned
- Invalid domain format: malformed domain input may result in an error response
- Unsupported record type: specifying record types outside the supported set may return null or empty results
