How this service works
One report on a domain's mail and DNS security: MX, SPF, DMARC, common DKIM selectors, MTA-STS with TLS-RPT, DNSSEC, reverse DNS of the mail servers, BIMI and CAA in one call, each as its own section with coded findings and evidence. Use when an agent must audit a domain's email security or build a domain health report; cheaper than calling the nine checks one by one. No score is computed.
Output
A structured report with a dedicated section for each of the nine checks (MX, SPF, DMARC, common DKIM selectors, MTA-STS with TLS-RPT, DNSSEC, reverse DNS of mail servers, BIMI, CAA), each containing coded findings (pass/warn/fail style) and the underlying DNS evidence. No aggregate score is computed.
Example use cases
Pre-send deliverability audit for a new domain
“Before we start sending marketing emails from newbrand.io, can you do a full email security health check on it — I want to see the MX, SPF, DMARC, DKIM, MTA-STS, DNSSEC, BIMI, and CAA records all in one report so I can spot any gaps?”
Client domain security review
“I need to audit acmecorp.com's entire email and DNS security setup for a client report — can you pull everything in one shot: MX, SPF, DMARC, DKIM selectors, MTA-STS, DNSSEC, reverse DNS, BIMI, and CAA?”
Investigating why emails are landing in spam
“Emails from techstartup.com keep getting flagged as spam — can you run a full DNS and mail security health check on techstartup.com to see if there's something wrong with their SPF, DMARC, DKIM, or MTA-STS setup?”
Technical details
Endpoint
GEThttps://api.probekit.dev/v1/domain/health?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive email and DNS security overview in a single API call rather than running nine separate checks. It is more cost-effective ($0.08 vs multiple individual calls) and faster when you need a holistic picture. Prefer individual ProbeKit endpoints only when you need deep customization (e.g., specifying exact DKIM selectors) or want to avoid paying for checks you don't need.
Side effects
- Invalid or non-existent domain returns an error or empty results per section
- DNS resolution timeouts may cause some sections to return partial data
- Domains with no mail setup (null MX) will show empty or null-MX findings for mail-related sections
- Network errors to public resolvers may result in DNSSEC status returning unknown
- Payment failure (x402) prevents the call from executing
