How this service works
Lookup DNS records for a domain
Output
Returns DNS record data for the specified domain and record type, including record values such as IP addresses, hostnames, priorities, or text strings depending on the requested record type (A, AAAA, MX, TXT, CNAME, NS, SOA, or SRV).
Example use cases
Verify email server configuration
“I need to check the MX records for our company domain to make sure our email is routing correctly to the right mail servers.”
Audit nameserver setup across domains
“Can you look up the nameservers for all our registered domains and tell me if they're pointing to the right DNS providers?”
Check SPF and DKIM records
“Please look up the TXT records for our domain so I can verify our SPF and DKIM settings are properly configured for email authentication.”
Technical details
Endpoint
GEThttps://dns-lookup.api.klymax402.com/api/lookupWhen to prefer
Use this endpoint when an agent needs to programmatically resolve DNS records for any domain, particularly useful for verifying email server configuration (MX), checking IPv4/IPv6 addresses (A/AAAA), inspecting TXT records for SPF/DKIM, or auditing nameserver setup. At $0.002 per call it's cost-effective for occasional lookups within agentic workflows.
Side effects
- Invalid domain name returns an error or empty result
- Unsupported record type causes a validation error
- Domain does not exist (NXDOMAIN) returns empty or error response
- Network timeout if upstream DNS resolver is slow
- Malformed domain string (e.g. spaces or invalid characters) may return 400 error
