How this service works
DNS lookup API for agents at $0.01 USDC. Call when you need A/AAAA/CNAME/MX/TXT/NS for domain routing, email delivery, or infra checks without running a recursive resolver. Returns structured records via x402—no API key, no subscription.
Output
Returns resolved DNS records for the queried domain, including one or more of A, AAAA, CNAME, MX, TXT, and NS records depending on what is configured and requested, enabling downstream checks on deliverability, routing, and domain health.
Example use cases
Example prompt
“Can you look up all the DNS records for sendgrid.com — I need to see the MX, TXT, and A records to verify their email delivery setup.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/dns-lookupWhen to prefer
Use this endpoint when an agent needs to programmatically resolve DNS records for deliverability validation, domain trust checks, email routing verification, or infrastructure inspection — especially when multiple record types (MX, TXT, A, NS) are needed in one call without standing up a custom DNS resolver.
Side effects
- Domain does not exist — NXDOMAIN response
- DNS timeout or upstream resolver failure
- Invalid domain format in request
- Requested record type not found for domain
- Rate limit or payment failure returns error
