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
A structured report containing WHOIS registration data, DNS record set, MX (mail exchanger) records with priorities, inferred mail policy (SPF/DKIM/DMARC signals), TLS certificate metadata, and discovered subdomains for the queried domain. If a baseline is provided, the response includes a comparison indicating changes to MX records since the observed_at timestamp.
Example use cases
Email infrastructure audit for a domain
“Check the full DNS and mail policy setup for acmecorp.com — I want to see the MX records, SPF/DKIM policy, and whether anything has changed since our last snapshot with mx.ionos.com at priority 10 observed on 2024-03-01.”
TLS certificate and subdomain discovery
“Run a domain intelligence lookup on startupxyz.io and give me the TLS certificate details and any subdomains you can find — I'm doing a security review.”
WHOIS and DNS due diligence before acquisition
“Get me the WHOIS registration info, DNS records, and MX configuration for targetdomain.biz — I need a full picture before we move forward with the acquisition.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-ionos?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive domain intelligence in a single call — WHOIS, DNS, MX, TLS, and subdomains — without signing up for an account or managing API keys. Particularly useful for one-off lookups, automated compliance checks, or when comparing MX records against a known baseline to detect mail routing changes. The x402/USDC pay-per-call model makes it cost-effective for sporadic, agent-driven queries. Prefer alternatives if you need high-volume batch lookups or require SLA guarantees.
Side effects
- Domain not found or unresolvable — returns empty or error response
- Invalid domain format exceeding 253 characters — schema validation failure
- Payment not received or x402 handshake fails — 402 response, no data returned
- Baseline object malformed (missing required fields) — request rejected
- Rate limiting or upstream DNS resolver timeout — partial or no data returned
