How this service works
Domain in, WHOIS, DNS, mail policy, TLS certificate and subdomains out. Pay per call in USDC over x402. No signup, no API key.
Output
Returns the current MX records (exchange hostnames and priorities) for the queried domain along with Mailgun-specific mail policy details. If a baseline is supplied, the response may indicate drift or changes relative to that snapshot.
Example use cases
Detect Mailgun usage for prospecting
“I'm building a sales list of companies that use Mailgun — can you check whether stripe.com routes its mail through Mailgun by looking up its MX records?”
Monitor MX record drift for security
“I have a baseline of MX records for mydomain.com from last week — priority 10 for smtp.mailgun.org observed at 2024-06-01T00:00:00Z. Can you check the current MX config and tell me if anything has changed?”
Audit email infrastructure before migration
“We're about to migrate email for shopify.com and need to know its current MX record setup and whether it's using Mailgun — can you pull that info?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-mailgun?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need MX record data and Mailgun mail policy intelligence for a domain, especially when you want to detect Mailgun usage or compare current MX records against a known baseline. Prefer this over generic WHOIS or full domain-intel endpoints when your focus is narrowly on mail exchange configuration rather than TLS certificates, subdomains, or WHOIS registrant data. Ideal for pay-per-call usage with no API key or account required.
Side effects
- Domain does not exist or is unresolvable — returns empty or error response
- Domain has no MX records configured — returns empty MX list
- Malformed domain input exceeding 253 characters — schema validation error
- Baseline records array exceeds 50-item limit — rejected with validation error
- Payment failure over x402 protocol — request not processed
- Transient DNS resolution timeout — may return partial or no data
