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
The agent receives structured MX record data for the queried domain, including the list of mail exchange hostnames and their associated priority values. If a baseline is provided, the response includes a comparison indicating whether records have changed, been added, or removed since the baseline observation timestamp.
Example use cases
Email deliverability audit for domain
“Can you check the MX records for sendgrid.net and tell me which mail exchange servers are configured and what their priorities are?”
Detect MX record drift since last check
“I recorded MX records for acmecorp.com on 2024-09-15 — the exchange was smtp.acmecorp.com at priority 5. Can you pull the current MX records and tell me if anything has changed?”
Verify mail routing before cutover
“We're migrating our mail for bigenterprise.io — can you confirm that the MX records currently point to inbound.proofpoint.com with priority 10, so I know the DNS cutover has propagated?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-mailbox-org?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need MX-specific mail exchange record data for a domain and want no-signup, pay-per-call access via x402 USDC micropayment. It is ideal for one-off or infrequent lookups where maintaining an API subscription is unnecessary, or for agents that need to compare current MX state against a known historical baseline to detect drift. Prefer it over general DNS APIs when the use case is narrowly focused on mail routing configuration.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist or has no MX records returns empty or not-found response
- Baseline schema mismatch (missing required fields) causes a 400-level error
- x402 payment failure or insufficient USDC balance prevents the call from completing
- Network timeout reaching authoritative DNS servers may return a transient error
