# OrionCMD DNS & Email-Auth Check

> OrionCMD DNS & Email-Auth Check is a paid API for AI agents from orioncmd-checks-mcp.dario-9fa.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Looks up DNS records (MX, NS, SPF, DMARC) and DNSSEC validation status for a given domain, returning a structured report of 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-dns-email-auth-check-e1d3cec7
```

Example prompt: Can you check the DNS and email-auth setup for example.com — I want to see the MX, SPF, and DMARC records and whether DNSSEC is properly signed and validated?

## When to prefer this

Choose this endpoint when you need a quick, structured DNS and email-authentication audit for a single domain — specifically when you care about MX routing, SPF/DMARC anti-spoofing posture, NS delegation, and DNSSEC validation in one call. It is ideal for agent workflows that need pay-per-call pricing without a subscription, and pairs well with sibling OrionCMD endpoints for TLS certificate and domain expiry checks. Prefer it over general-purpose DNS tools when you need a clean JSON summary with a findings list rather than raw zone data.

## Known failure modes

- Missing 'domain' query parameter returns a validation error
- Invalid or non-existent domain may return empty records or a lookup failure
- Payment not completed (x402 protocol) results in a 402 Payment Required response
- Network or DNS resolver timeouts may cause delayed or failed responses
- Domains with no SPF/DMARC records will show empty arrays for those record types

## How this service works

Pay-per-call website checks for agents: TLS certificate (from CT logs), DNS/email-auth, domain expiry, and a site-health bundle. Also available as an MCP server at /mcp.

## Output

Returns a JSON object containing: the queried domain name, DNSSEC validation status (e.g. 'signed and validated (AD bit set)'), a records map with MX, NS, SPF, and DMARC entries as arrays, and a findings array listing any detected issues or misconfigurations.
