# Lookproof Domain Email & DNS Security Health Check

> Lookproof Domain Email & DNS Security Health Check is a paid API for AI agents from api.lookproof.dev, paid per call via x402, $0.08/call, status unknown (last checked 2026-10-31).

Returns a comprehensive single-call audit of a domain's email and DNS security posture, covering MX, SPF, DMARC, DKIM, MTA-STS, TLS-RPT, DNSSEC, reverse DNS, BIMI, and CAA records with coded findings per section.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability lookproof-domain-email-dns-security-health-check-2165fbad
```

Example prompt: Can you run a full email and DNS security audit on example.com — I want to see MX, SPF, DMARC, DKIM, MTA-STS, DNSSEC, reverse DNS, BIMI, and CAA all in one go?

## When to prefer this

Use this endpoint when you need a complete email and DNS security picture for a domain in a single API call. It is more efficient and cheaper than calling individual checks (SPF-only, DMARC-only, DKIM-only, etc.) separately. Prefer it for building domain health dashboards, onboarding audits, vendor assessments, or deliverability pre-flight checks where all nine signal types are relevant. If you only need one specific check (e.g. BIMI alone), a dedicated sibling endpoint may be more targeted.

## Known failure modes

- Invalid or non-existent domain returns an error or empty sections
- DNS resolution timeouts may cause partial results for some sections
- Domains with no mail configuration (no MX) will return empty findings for email-dependent sections
- Rate limiting or payment failure returns 402 or 429 response
- Malformed domain input (e.g. with protocol prefix) may be rejected

## How this service works

Check SPF, DMARC, DKIM, MTA-STS, DNSSEC and more, with results that explain what was found and why. Free browser checks and a pay-per-request API with x402.

## Output

A structured report divided into labelled sections — one per check (MX, SPF, DMARC, DKIM common selectors, MTA-STS, TLS-RPT, DNSSEC, reverse DNS of mail servers, BIMI, CAA) — each containing coded findings (pass/warn/fail style indicators) and the raw DNS evidence. No aggregate score is computed; each section stands independently.
