## 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 email-security-record-checker-e5661ac2 -d '<json body>'
```

Example prompt: Can you check whether example.com has its MX, SPF, and DMARC email security records properly set up?

## When to prefer this

Use this endpoint when you need a quick, low-cost check of a domain's email security posture — specifically MX, SPF, and DMARC record presence — without needing full DNS record dumps or deliverability scoring. Ideal for pre-outreach validation, vendor due diligence, or phishing risk assessments where you just need boolean pass/fail signals on the three core email authentication pillars.

## Known failure modes

- Invalid or malformed URL input returns an error
- Domain does not exist or is unreachable, resulting in all false or an error response
- DNS lookup timeouts for slow or unresponsive nameservers
- Private or localhost URLs may be rejected
- Rate limiting if too many requests are made in rapid succession
