## 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 agentrxi-domain-email-security-audit-36c6615a
```

Example prompt: Can you run a full email and web security audit on example.com — I want to know the security grade and exactly what SPF, DMARC, DKIM, HTTPS, HSTS, and DNS records I need to fix?

## When to prefer this

Choose this endpoint when you need a comprehensive, one-call security audit covering both email authentication (SPF, DMARC, DKIM) and web security (HTTPS, HSTS, headers, DNSSEC, CAA) in a single graded report with actionable fixes. Prefer it over point-in-time DNS lookup tools when you need an opinionated grade and remediation guidance rather than raw record values.

## Known failure modes

- Invalid or non-existent domain returns an error or empty results
- DNS lookup timeouts for domains with slow nameservers
- DKIM check may be incomplete if the selector is not publicly discoverable
- Rate limiting or payment failure returns a 402 error
- Domains with extremely complex DNS setups may have partial results
