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 domain's current MX records (exchange and priority), identifies whether ImprovMX is the configured mail provider, and if a baseline is supplied, provides a diff indicating what has changed since the baseline observation timestamp.
Example use cases
Detect unauthorized MX record change
“Check if acmecorp.com's MX records have changed since my baseline snapshot from 2024-05-15 — the baseline had mx.improvmx.com at priority 10. Alert me if anything is different.”
Audit mail provider for onboarded customer
“I'm onboarding a new client at startup.io — can you look up their MX records and tell me if they're using ImprovMX or something else for email?”
Verify ImprovMX setup before sending
“Before I send transactional emails through ImprovMX for the domain myshop.store, can you confirm the MX records are actually pointing to ImprovMX correctly?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-improvmx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to verify ImprovMX mail routing configuration or detect MX record drift against a known baseline, without requiring an API key or signup. It is ideal for lightweight, pay-per-call DNS/mail checks in automated pipelines where per-query USDC micropayments via x402 are acceptable. Prefer alternatives if you need full WHOIS, TLS, or subdomain data — those may be on sibling endpoints.
Side effects
- Domain does not exist or has no MX records — returns empty records array
- Domain name exceeds 253 characters — rejected by input validation
- Baseline records array exceeds 50 items — rejected
- Payment not provided or insufficient USDC — 402 Payment Required response
- DNS resolution timeout — transient error, retry recommended
- Malformed domain string — 400 Bad Request
