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
Returns a structured payload covering: WHOIS registration details (registrar, registrant, expiry 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. When a baseline is provided, the response can highlight changes since the previous observation.
Example use cases
Pre-acquisition domain due diligence
“Before we finalize the purchase of acmecorp.io, can you check its WHOIS ownership, DNS setup, TLS certificate validity, mail policy, and any known subdomains so I can assess its current infrastructure?”
Email deliverability configuration audit
“We're having email deliverability issues with newsletter.co — can you check their SPF, DKIM, and DMARC mail policy settings along with their DNS records so I can see what's misconfigured?”
DNS change monitoring baseline comparison
“I recorded the DNS records for example.com last week. Here's my baseline snapshot — can you pull the current domain intel for example.com and compare to see if anything has changed?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-dns-made-easy?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, no-signup call that aggregates WHOIS, DNS, mail policy, TLS, and subdomain data for a domain in one shot. Ideal for AI agents that need domain intelligence on-demand without managing API keys or subscriptions — the x402 micropayment model means you pay only for what you query. Prefer this over separate WHOIS-only or DNS-only APIs when you need a holistic domain profile for due diligence, security auditing, or change detection workflows.
Side effects
- Domain not found or unregistered — returns empty or error for non-existent domains
- Rate limiting or payment failure — x402 payment not accepted or insufficient USDC balance
- Invalid domain format — domain exceeds 253 characters or is malformed
- WHOIS privacy shielding — registrant details may be redacted by privacy proxy services
- TLS certificate data unavailable — if domain has no HTTPS endpoint
- Subdomain enumeration limited — passive enumeration may miss dynamically created subdomains
- Baseline records malformed — if observed_at or records array violates schema constraints
