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 report for the queried domain including: WHOIS registration data (registrar, dates, registrant), full DNS record set, mail policy settings (SPF, DKIM, DMARC), TLS/SSL certificate details (issuer, validity, SANs), and discovered subdomains. When a baseline is provided, delta information may be highlighted.
Example use cases
Investigate a suspicious phishing domain
“I got a suspicious email from paypa1-security.com — can you look it up and give me the WHOIS owner, DNS records, TLS cert details, and any subdomains so I can tell if it's a scam?”
Audit email security configuration
“Can you check the mail policy settings for acmecorp.com? I want to know if they have SPF, DKIM, and DMARC properly configured.”
Monitor DNS changes against a baseline
“Here's a baseline snapshot of example.com's DNS records from last week — can you run a fresh lookup and tell me if anything has changed?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-strato?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-faceted domain intelligence snapshot in a single call — covering WHOIS, DNS, mail policy, TLS, and subdomains together — without signing up for an account or managing API keys. It is particularly well-suited for ad-hoc agent workflows, security investigations, or domain audits where pay-per-call USDC pricing via x402 is acceptable. Prefer this over dedicated single-purpose DNS or WHOIS APIs when breadth of domain data matters more than depth in one specific record type.
Side effects
- Domain not found or unresolvable — returns empty or partial data
- Invalid domain format (exceeds 253 characters or malformed) — input validation error
- TLS certificate absent or expired — cert section may be null
- WHOIS data redacted for privacy-protected domains — partial response
- Payment failure via x402 — call not executed, no data returned
- Rate limiting or upstream DNS resolver failures — timeout or error response
