# OrionCMD Email Authentication Security Check

> OrionCMD Email Authentication Security Check is a paid API for AI agents from api.orioncmd.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Checks a domain's email authentication configuration including SPF, DKIM, DMARC, and MTA-STS, returning a security score and plain-English findings.

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 orioncmd-email-authentication-security-check-44370ab1
```

Example prompt: Can you check the email authentication setup for stripe.com and tell me if their SPF, DKIM, and DMARC are configured correctly, and give me a security score?

## When to prefer this

Choose this endpoint when you need a fast, passive read of a domain's email authentication posture (SPF, DKIM, DMARC, MTA-STS) without triggering active scans. It is ideal for pre-send audits, vendor due diligence, phishing risk assessment, and client-facing security reports. Prefer it over general DNS lookup tools when you specifically need email security scoring and plain-English findings in one call.

## Known failure modes

- Domain does not exist or is unreachable — may return empty or null fields
- Domain has no email authentication records — returns present: false for SPF/DMARC/DKIM with low score
- Invalid domain input format — likely returns a 400 or validation error
- Rate limiting or payment failure — returns 402 or 429
- DKIM selector discovery may return empty array if no common selectors are detected

## How this service works

Passive-first monitoring for uptime, SSL/TLS, DNS, email security, internet exposure, WordPress core advisories, and breach exposure — with reachability probes, optional authorized scans, plain-English alerts, and client-ready reports.

## Output

Returns a JSON object with SPF validity and DNS lookup count, DKIM selectors found, DMARC policy details (policy mode, pct, rua), MTA-STS policy mode, a numeric security score (0–100), whether the domain receives mail, and a list of plain-English findings describing specific misconfigurations or gaps.
