How this service works
Look up DNS records for any domain — A, AAAA, MX, NS, TXT, CNAME, SOA. Use for domain diagnostics, mail server lookup, DNS resolution, and domain verification.
Output
Returns a structured object containing the domain name plus arrays of records by type: A (IPv4 addresses), AAAA (IPv6 addresses), MX (mail exchange), NS (nameservers), TXT (text records), CNAME (canonical name), and a SOA (start of authority) object.
Example use cases
Example prompt
“Can you look up all the DNS records for github.com — I need to see the A, MX, NS, and TXT records?”
Technical details
Endpoint
GEThttps://dns.x402tools.xyz/v1/lookupWhen to prefer
Use this endpoint when an agent needs to programmatically inspect DNS infrastructure for any domain — verifying email server configuration, resolving IP addresses, checking nameservers, or validating SPF/DKIM TXT records. It covers all major DNS record types in a single call, making it efficient for comprehensive DNS audits. Prefer this over manual dig/nslookup when operating in an automated or agentic workflow.
Side effects
- Invalid or malformed domain name returns an error response
- Non-existent domain (NXDOMAIN) may return empty record arrays
- Network timeout if upstream DNS resolver is unreachable
- Missing required 'domain' query parameter returns a 400-style error
- Payment failure (402) if USDC balance is insufficient
