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
A structured response containing: WHOIS registration data (registrar, registrant, dates), full DNS record set (A, AAAA, MX, NS, TXT, CNAME etc.), mail policy records (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and a list of discovered subdomains. If a baseline snapshot is provided, results may include change detection against that baseline.
Example use cases
Email security policy audit
“Check the mail policy setup for acmecorp.com — I need to know if they have valid SPF, DKIM, and DMARC records configured before we send them a contract.”
Vendor TLS certificate verification
“Look up the TLS certificate details for vendor-portal.example.com and tell me when it expires and who issued it — I want to make sure it's legitimate before we integrate.”
Subdomain enumeration for recon
“Enumerate all the subdomains you can find for targetdomain.io and pull their DNS records — I'm doing a security assessment and need to map out their infrastructure.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-infomaniak?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call domain intelligence profile combining WHOIS, DNS, mail policy, TLS, and subdomain data without signing up for an API key. Ideal for security assessments, vendor due diligence, or monitoring domain changes. The baseline diff feature makes it especially useful for change detection workflows. At $0.009/call over x402, it suits pay-as-you-go agents that need occasional domain lookups without a subscription.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist (NXDOMAIN) results in empty or error response
- WHOIS data may be redacted for privacy-protected registrations
- TLS certificate lookup fails if the domain has no HTTPS service
- Rate limits or upstream WHOIS/DNS resolver timeouts can cause partial results
- Payment failure via x402 results in 402 response before any data is returned
