How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object with ok and paid flags, along with the MX record set for the queried domain — including each mail exchange hostname and its priority value as published in DNS.
Example use cases
Email deliverability debugging
“Can you pull the MX records for acme-corp.com? I'm trying to figure out why emails aren't delivering and want to see how their mail servers are configured.”
Domain mail server verification
“Check the MX records for mycompany.io — I need to confirm that Google Workspace mail servers are listed before I finish setting up our email.”
Competitor infrastructure research
“Look up the MX records for stripe.com so I can see which email provider they're routing their mail through.”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/network/dns-mx-records?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call MX record lookup without any API key setup. It's ideal for AI agents that need on-demand DNS MX resolution for email validation, deliverability checks, or infrastructure reconnaissance, and where the x402 micropayment model (USDC on Base) is already integrated. Prefer this over full DNS suites if you only need MX records and want zero-registration simplicity.
Side effects
- Domain does not exist or has no MX records — returns empty record set or NXDOMAIN
- Invalid or malformed domain name input — may return an error or empty response
- Payment failure via x402 — 402 response if USDC payment is not completed
- Network or DNS resolver timeout — upstream DNS query may fail intermittently
- Rate limiting or worker-level errors on Cloudflare — 5xx responses possible
