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 structured response containing: WHOIS registration data (registrar, dates, registrant), DNS records (A, AAAA, MX, NS, TXT, CNAME, etc.), mail policy records (SPF, DKIM, DMARC), TLS/SSL certificate details (issuer, validity, SANs), and a list of discovered subdomains.
Example use cases
Audit email security posture of a vendor
“Check the mail policy for acme-corp.com — I want to see their SPF, DKIM, and DMARC records to make sure they're properly configured before we integrate with them.”
Investigate a suspicious phishing domain
“I got a suspicious email from support@secure-paypa1.net — can you look up the WHOIS, DNS records, and TLS cert for secure-paypa1.net so I can see if it's a phishing domain?”
Map infrastructure of a competitor domain
“Give me the full domain intel on shopify.com — DNS records, subdomains, name servers, and TLS certificate info, everything you can pull.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-dnsimple?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, pay-per-call call that aggregates WHOIS, DNS, mail policy, TLS, and subdomain data in one shot without requiring an API key or subscription. It is ideal for ad-hoc domain investigations, security audits, or enriching a pipeline with domain metadata using micro-payments. Prefer alternatives if you need bulk batch lookups, very high-frequency polling, or need guaranteed SLA uptime.
Side effects
- Invalid or malformed domain name returns validation error
- Domain does not exist (NXDOMAIN) may return empty or partial results
- Payment failure via x402 if insufficient USDC balance
- Rate limiting or temporary unavailability of upstream DNS/WHOIS resolvers
- Some WHOIS data may be redacted due to GDPR or privacy proxies
- TLS or subdomain enumeration may be incomplete for heavily firewalled domains
