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 an analysis of the domain's MX records with specific attention to Barracuda mail filtering indicators, mail policy details, and (when a baseline is provided) a comparison highlighting any changes in mail exchange configuration since the baseline was recorded.
Example use cases
Barracuda gateway detection for vendor
“I need to know if acmecorp.com routes its email through Barracuda — pull its MX records and tell me what mail security gateway they're using.”
MX drift monitoring from baseline
“Check whether the MX records for clientdomain.org have changed since our baseline snapshot from 2024-05-15 — the baseline had mx1.clientdomain.org at priority 10 and mx2.clientdomain.org at priority 20.”
Email security audit for due diligence
“I'm doing a security audit on targetcompany.io — can you pull its MX records and tell me if they're using Barracuda and what their mail policy looks like?”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-barracuda?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use, no-signup MX and Barracuda mail policy intelligence for a specific domain — especially when you want to compare current MX state against a known baseline or detect use of Barracuda email security gateways, and you prefer micropayment (USDC/x402) access over subscription-based DNS API services.
Side effects
- Invalid or non-existent domain returns an error or empty record set
- Domain exceeds 253 characters triggers schema validation failure
- Payment not fulfilled via x402 results in HTTP 402 response before data is returned
- Baseline object missing required fields (domain, observed_at, records) causes a validation error
- MX records genuinely absent for a domain may return empty results, not an error
- Network timeouts during live DNS resolution may cause slow or failed responses
