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 comprehensive domain intelligence report including WHOIS registration data, resolved DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), email authentication policy (SPF, DKIM, DMARC), TLS certificate metadata, and a list of known subdomains. When a baseline is supplied, can surface diffs in MX records.
Example use cases
Verify Proton Mail MX configuration
“Check if protonmail.com is correctly configured to use Proton Mail servers — I want to see the current MX records and whether they match the expected Proton Mail exchange hosts.”
Audit email security policy for a domain
“Pull the full DNS and mail policy details for acmecorp.com — I need to know if they have valid SPF, DKIM, and DMARC records set up, plus their current MX setup.”
Detect MX record drift from baseline
“Look up domain intelligence for example.com and compare the current MX records against my baseline from two weeks ago where mail.example.com had priority 5 — has anything changed?”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-proton-mail?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-signup, pay-per-call solution for comprehensive domain intelligence including WHOIS, DNS, mail policy, TLS, and subdomains in a single call, especially when monitoring MX record changes against a known baseline or verifying Proton Mail configurations. Prefer it over generic DNS lookup tools when you need all domain layers in one response and want to pay in USDC without managing API keys.
Side effects
- Invalid or non-existent domain returns an error or empty record set
- Malformed baseline object (missing required fields) causes a validation error
- Domain exceeding 253 characters is rejected
- Payment failure via x402 results in 402 response and no data returned
- WHOIS rate limiting or registry unavailability may cause partial results
- TLS or subdomain enumeration may time out for large or slow domains
