Domain Intel — MX / domainfactory Baseline Check
x402
Domain Intel — MX / domainfactory Baseline Check is a paid API for AI agents from dns.halowerk.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-12).
Given a domain and an optional MX-record baseline, returns WHOIS, DNS, mail policy (SPF/DKIM/DMARC), TLS certificate details, and subdomains — with diff support against a prior MX snapshot.

How this service works
Requires an unauthenticated caller-owned baseline; returns real current NS/MX records, added/removed sets and tri-state target-provider transition. Current DNS comes from one bounded native recursive-resolver query; existing Dossier provides context. Resolver caching may apply; no account ownership or global migration-completion claim. Existing provider patterns are reused without new invented attribution. At most50records,domain253chars,9sbudget; DNSsubquery2s/oneattempt. Unknown provider remai
Output
Returns a comprehensive domain intelligence report including: WHOIS registrant/registrar/expiry data, full DNS record set, MX exchange list with priorities, mail policy records (SPF, DKIM, DMARC), TLS certificate details (issuer, validity, SANs), discovered subdomains, and — when a baseline is provided — a diff highlighting changes in MX configuration since the baseline was observed.
Example use cases
Email security audit for a client domain
“Run a full domain intel check on acme-corp.com — I need the WHOIS details, all DNS records, their SPF/DKIM/DMARC policy, current MX records, and the TLS certificate info so I can audit their email security posture.”
MX change detection for brand monitoring
“Check domainfactory.de right now and compare the MX records against this baseline I captured on 2025-05-15: mx1.domainfactory.de at priority 10 and mx2.domainfactory.de at priority 20 — tell me if anything has changed.”
Subdomain enumeration for threat intelligence
“I'm doing threat intel on suspicious-domain.io — can you pull the full domain intel including all discoverable subdomains, the TLS certificate, and WHOIS ownership info?”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-domainfactory?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, pay-per-use snapshot of a domain's full technical posture — WHOIS, DNS, mail policy, TLS, and subdomains — without signing up for a SaaS platform. Especially valuable when you also have a prior MX baseline and want change detection built into the same call. Prefer it over manual DNS tools when working in an automated agent pipeline that can pay $0.009 USDC per lookup via x402.
Side effects
- Domain not found or unresolvable — no DNS data returned
- Invalid domain format (exceeds 253 characters or malformed) — input validation error
- WHOIS rate limiting or registry unavailability — partial results with WHOIS omitted
- TLS certificate absent or expired — certificate section returns null or error flag
- Baseline MX schema invalid (missing required fields: domain, observed_at, records) — request rejected
- Payment failure over x402 — 402 response before any data is returned
- Subdomain enumeration returns empty set for well-protected or sparsely delegated domains
