## 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 api-zavod-mail-security-checker-f3d65132
```

Example prompt: Can you check the email security setup for stripe.com — specifically whether it has MX, SPF, and DMARC records configured?

## When to prefer this

Use this endpoint when you need a quick, combined lookup of all three major email security DNS record types (MX, SPF, DMARC) in a single call. It is ideal for bulk domain auditing, pre-send deliverability checks, or security assessments where you want a concise pass/fail flag alongside the raw record data. Prefer it over generic DNS lookup endpoints when the specific goal is email security validation rather than general DNS inspection.

## Known failure modes

- Domain does not exist — returns empty arrays and all boolean flags as false
- DNS timeout — may return empty results without distinguishing from a genuinely unconfigured domain
- Invalid domain format in query parameter — may return error or empty response
- Domain has no email configuration at all — valid response but all flags false and all arrays empty

## How this service works

MX, SPF and DMARC check / Проверка почтовой защиты домена

## Output

Returns a JSON object with the domain name, arrays of MX, SPF, and DMARC DNS record values, and boolean flags (есть_mx, есть_spf, есть_dmarc) indicating whether each record type is present for the queried domain.
