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 a structured response containing: WHOIS registration details, full DNS record set, mail policy records (SPF, DKIM, DMARC), TLS/SSL certificate metadata, discovered subdomains, and optionally a diff against a provided MX baseline indicating any changes in mail exchange configuration.
Example use cases
Email infrastructure audit for onboarding
“Run a full domain check on acme-corp.com — I need WHOIS, DNS, SPF/DKIM/DMARC policy, TLS cert, and subdomains so I can audit their email setup before we onboard them.”
MX change detection for domain monitoring
“Check domain-watch.io's MX records right now and compare them against the baseline I set last Monday: mailhost.domain-watch.io at priority 5, observed on 2024-05-27. I want to know if anything has changed.”
Competitive domain reconnaissance
“Give me the full intel on rivalstartup.com — WHOIS ownership, all DNS records, their TLS cert details, and any subdomains you can find. No signup, just pay as you go.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-strato?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive, multi-signal domain intelligence (WHOIS + DNS + mail policy + TLS + subdomains) in a single call without API key registration, especially when comparing current MX records against a known baseline. Ideal for ad-hoc domain audits, security investigations, onboarding checks, or agent workflows that need pay-as-you-go domain enrichment via x402 micropayments. If you only need a single record type (e.g., pure DNS lookup), a dedicated DNS resolver may be cheaper; if you need bulk domain processing, batch-oriented alternatives may be more efficient.
Side effects
- Invalid or malformed domain name (exceeds 253 chars or bad format) — validation error
- Domain does not exist or is unregistered — empty or null WHOIS/DNS results
- MX baseline schema violation (missing required fields: domain, observed_at, records) — 400 bad request
- Payment not completed via x402 — 402 Payment Required with USDC payment instructions
- Network timeout reaching upstream DNS/WHOIS services — 502 or 504 error
- Rate limiting or abuse detection on upstream registries — partial or throttled results
