How this service works
Live DNS lookup for a domain: returns name, type and records[]. Supported record types: A, AAAA (addresses as strings), MX ({exchange, priority} objects), TXT (each record an array of its strings), NS and CNAME (hostnames). For SPF, DMARC or a full mail-security read use spf-check, dmarc-check or email-deliverability.
Output
Returns the DNS records of the requested type for the given domain, such as IP addresses for A records, mail server hostnames for MX records, or verification strings for TXT records.
Example use cases
Example prompt
“What are the MX records for gmail.com?”
Technical details
Endpoint
GEThttps://agent402.tools/api/dns?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically resolve DNS records for a domain — e.g. verifying domain ownership via TXT records, finding mail servers, or checking IP addresses — especially within an x402 micropayment-enabled workflow at low cost per call.
Side effects
- Domain does not exist — NXDOMAIN or empty record set returned
- Unsupported record type requested — only A, AAAA, MX, TXT, NS, CNAME are supported
- Malformed domain name input — validation error
- DNS timeout or upstream resolver failure
- Payment not processed — 402 response if USDC payment not included
