Example prompt: Can you look up the published DMARC policy for acmecorp.com? I want to know the policy mode and any reporting addresses they've configured, as part of our vendor screening process.

## When to prefer this

Use this endpoint when you need a fast, low-cost DNS-only lookup of a domain's published DMARC policy for vendor screening, third-party risk assessment, or compliance workflows. Prefer this over broader email security tools when you only need the DMARC record and don't need to send test emails, verify inbox existence, or check SPF/DKIM separately.

## Known failure modes

- Domain has no DMARC record published — returns empty or not-found result
- Invalid or malformed domain input — returns validation error
- DNS resolution failure — transient network error
- Domain does not exist in DNS — NXDOMAIN response
- DMARC record is malformed and cannot be parsed — returns raw record with parse error
