How this service works
Web tools: search, page to Markdown or screenshot, company profile and jobs, sitemaps, RDAP, IP.
Output
A structured JSON report containing results for each requested check section (email, dns, tls). The email section includes SPF details (present, all_policy, dns_lookup_count, issues), DMARC configuration (policy, subdomain_policy, pct, rua, issues), DKIM selectors found, MTA-STS status, whether the domain accepts mail, and an overall email security score out of 8. Additional notes and the list of checks performed are also returned.
Example use cases
Email deliverability audit before campaign
“Before we send our next marketing campaign, can you check acme.com's email security configuration — SPF, DMARC, and DKIM — and tell me if anything looks misconfigured or missing?”
Security posture check for acquired domain
“We just acquired newstartup.io — can you run a full email and TLS inspection on it so I can see what security gaps we need to fix?”
Verify DMARC enforcement on own domain
“Can you check whether mycompany.com has a strict DMARC policy in place, and whether DKIM selectors are properly configured?”
Technical details
Endpoint
POSThttps://web.tanod.dev/v1/domain/inspect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, scored breakdown of a domain's email security (SPF, DMARC, DKIM, MTA-STS) rather than raw DNS lookups. It's ideal for deliverability audits, security posture assessments, and onboarding checks for new domains. Prefer it over generic DNS resolvers when you need interpreted results and actionable issue lists rather than raw record values.
Side effects
- Invalid domain name format returns a validation error
- Domain does not exist in DNS — partial or empty results returned
- Network timeout reaching external DNS or TLS endpoints
- Requesting more than 3 check types or an invalid check type enum causes a 400 error
- DKIM selector discovery may miss non-standard selectors
