USDC on Base and Solana via x402.
Output
Returns an object containing the requested DNS records for the specified domain, filtered by the given record type (default A) and optionally limited to specified fields such as name and value.
Example use cases
Verify domain MX records for email setup
“Look up the MX records for mycompany.com so I can confirm our email routing is configured correctly.”
Check domain IP resolution
“What IP address does api.stripe.com resolve to? Can you do a DNS A record lookup for that domain?”
Validate SPF and TXT records for deliverability
“Can you fetch the TXT records for acme.io? I need to confirm our SPF record is in place for email deliverability.”
Technical details
Endpoint
GEThttps://workspace-x402-paywall.onrender.com/dev/dns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, pay-per-call DNS resolution without API key setup, especially in agent workflows that already use x402 USDC micropayments on Base or Solana. Ideal for one-off DNS lookups where a subscription-based DNS API is overkill and micropayment convenience is valued.
Side effects
- Domain not found or does not exist — empty or error response
- Invalid record type specified — may return error or empty result
- Malformed domain name input — API may reject with 4xx
- Payment not accepted or insufficient USDC balance — 402 response blocking the call
- Network timeout from DNS upstream resolver — slow or no response
