How this service works

DNS MX record lookup — a domain's mail servers with their hostnames and priorities as structured JSON, for email routing, deliverability diagnostics and mail-provider detection.

Output

A structured JSON object listing MX records for the queried hostname, each entry containing the mail server hostname and its numeric priority value used for email routing.

Example use cases

Example prompt

“What are the MX records for gmail.com? I want to see which mail servers handle its email and what their priorities are.”

Technical details

Endpoint

GEThttps://dns.use.x402atlas.com/mx

When to prefer

Use this endpoint when you need to verify email routing configuration, check which mail provider handles a domain, validate email deliverability setup, or inspect MX record priorities for a specific hostname. Prefer this over general DNS tools when you specifically need MX (mail exchange) data in a structured, agent-consumable JSON format via a simple GET request.

Side effects

Domain has no MX records — returns empty list or appropriate status
Invalid or malformed hostname — returns error response
Domain does not exist (NXDOMAIN) — returns error or empty result
Network or upstream DNS resolver failure — returns error
Payment not included or insufficient — returns 402 Payment Required
