## 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 agentdiet-email-deliverability-dns-verifier-7e9ac64e
```

Example prompt: Can you check if john.doe@example.com is a real, deliverable email — not a burner or role account — and whether the domain has valid MX, SPF, and DMARC records set up?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal email check combining syntax, disposable provider detection, role account flagging, and live DNS validation in a single call — especially useful for lead qualification, signup gating, or email list hygiene where you need more than just syntax checking.

## Known failure modes

- Missing or malformed email parameter returns an error
- DNS timeout for domains with unresponsive nameservers may return partial results
- Unknown or very new disposable providers may not be flagged
- Private or internal domains may not have publicly resolvable DNS records

## How this service works

Validates email syntax, disposable/burner provider status, role accounts, and live DNS MX/SPF/DMARC records. (Live x402 v2, IETF MPP & MCP endpoint at https://agentdiet.dev/v1/email-check)

## Output

Returns a structured report indicating whether the email passes syntax validation, whether the domain belongs to a known disposable or burner provider, whether the address is a role account (e.g. admin@, noreply@), and the live DNS lookup results for MX, SPF, and DMARC records including their values and presence/absence.
