## 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-policy-lookup-946f112f -d '<json body>'
```

Example prompt: Can you look up the DMARC policy for paypal.com and tell me whether they have rejection enforcement enabled and what reporting addresses are configured?

## When to prefer this

Use this endpoint when you need to programmatically retrieve and parse a domain's DMARC DNS policy for security review, vendor assessment, compliance auditing, or phishing risk analysis. It is DNS-only and read-only, making it safe and idempotent. Prefer it over manual DNS tooling when you need structured, parsed output rather than raw TXT records.

## Known failure modes

- Domain has no DMARC record published — returns empty or error indicating no _dmarc TXT record found
- Invalid or malformed domain input — may return a DNS resolution error
- Domain does not exist in DNS — NXDOMAIN error returned
- DMARC record is malformed or non-standard — partial parse returned
- DNS timeout or transient resolution failure — network error response

## How this service works

DMARC policy lookup for Security review: Return and parse the published DMARC policy and reporting addresses. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the parsed DMARC DNS TXT record for the queried domain, including the policy tag (p= none/quarantine/reject), subdomain policy (sp=), aggregate reporting addresses (rua), forensic reporting addresses (ruf), and other DMARC record tags. Data is sourced from live DNS only; no email is sent and no inbox is verified.
