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 the current MX records for the domain (exchange hostnames and priorities), a flag or indicator showing whether Proofpoint is detected in the mail routing path, and optionally a comparison against the provided baseline MX records including any detected changes.
Example use cases
Prospect email security stack research
“Check if salesforce.com routes its inbound email through Proofpoint — I need to know their mail security vendor before our pitch.”
MX baseline drift detection
“I captured MX records for example.com last month — exchange 'mx1.example.com' at priority 10, observed on 2024-06-01. Run it now and tell me if anything changed or if they've moved to Proofpoint.”
Competitor email infrastructure audit
“Pull the current MX records for competitor.io and tell me whether they're using Proofpoint as their email gateway.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-proofpoint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-signup, pay-per-call check specifically for Proofpoint MX routing detection on a domain, especially when you want to compare against a known MX baseline. Prefer it over general DNS APIs when the specific question is whether a domain's mail flows through Proofpoint, and when you want to avoid API key management by paying micro-amounts in USDC via x402.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain with no MX records returns empty MX array
- Baseline records with missing required fields (exchange, priority) cause schema validation failure
- Network timeout if upstream DNS resolution is slow
- Payment failure via x402 if USDC balance is insufficient or x402 protocol handshake fails
