How this service works
Machine-readable settlement service
Output
Returns a machine-readable DNS response containing the AAAA record(s) for the queried domain, including the associated IPv6 address(es) and relevant DNS metadata such as TTL values. The response schema is open-ended and may include additional DNS resolution details.
Example use cases
IPv6 connectivity verification
“Check whether cloudflare.com has any AAAA records so I can confirm it supports IPv6 connections.”
Infrastructure DNS audit
“Pull the AAAA DNS records for api.mycompany.com — I need to verify our IPv6 entries are configured correctly before the migration.”
Domain IPv6 reachability check
“Look up the AAAA records for github.com so I can see which IPv6 addresses it's pointing to right now.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/dns.records--aaaa-lookupWhen to prefer
Choose this endpoint when you specifically need IPv6 (AAAA) DNS records for a domain and want a machine-readable, pay-per-call result without managing your own DNS resolver infrastructure. It is appropriate for lightweight, on-demand DNS lookups in agent workflows where cost per call ($0.001 USDC) is acceptable and no free alternative is wired in. Prefer a traditional DNS library or free resolver API if you need bulk lookups or have no x402 payment capability.
Side effects
- Domain does not exist (NXDOMAIN) — returns empty or error result
- Domain exists but has no AAAA records — returns empty record set
- Invalid domain name format in input — may return validation error
- Network or upstream DNS resolver timeout — service error response
- Payment settlement failure — x402 payment not accepted, request blocked
