## 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 dmarc-enforcement-check-for-email-operations-6e6f0040 -d '<json body>'
```

Example prompt: Can you check the DMARC enforcement level for paypal.com — I want to know if it's set to reject, quarantine, monitor, or if it's missing entirely?

## When to prefer this

Use this endpoint when you need a fast, read-only classification of a domain's DMARC enforcement posture using DNS data. Ideal for security audits, vendor due diligence, phishing risk assessments, or any workflow that needs to programmatically determine whether a domain enforces email authentication at the reject, quarantine, or monitor level. Prefer this over full email deliverability checks when you only need the policy classification and not inbox verification or sending behavior.

## Known failure modes

- Domain does not exist in DNS — may return 'missing' or an error
- Malformed domain input (e.g. including http:// prefix) may cause lookup failure
- Temporary DNS resolution failures may result in timeouts or errors
- Domain has a syntactically invalid DMARC record — classification may be ambiguous

## How this service works

DMARC enforcement check for Email operations: Classify the published DMARC policy as monitor, quarantine, reject, or missing. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the DMARC policy classification for the queried domain — one of: 'reject' (strict enforcement), 'quarantine' (messages flagged), 'monitor'/'none' (policy exists but not enforced), or 'missing' (no DMARC record found). Based purely on DNS TXT record lookup at the _dmarc subdomain; no email is sent and no inbox is verified.
