## 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-domain-verify-527e2325
```

Example prompt: Can you verify whether john.doe+test@gmail.com is a real, deliverable address — I want to know if it's disposable, a role address, which mail provider it uses, and whether the domain has SPF and DMARC set up?

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one email validation signal beyond simple syntax checking — especially when you need deliverability verdicts, mail provider identification, disposable email detection, role-address filtering, and SPF/DMARC checks in a single call. Prefer it over dedicated disposable-email-only checkers (like the sibling disposable-email-check endpoint) when you want the full picture for CRM enrichment, lead qualification, or signup gating at $0.01 per address.

## Known failure modes

- Invalid or malformed email address input returns a syntax error verdict
- Domain with no DNS records returns an unresolvable error and 'no' verdict
- Rate limiting or network timeout may cause delayed or failed DNS lookups
- Newly registered domains may not yet have MX records even if legitimate
- Edge-case disposable providers not yet in the blocklist may pass as clean
- Plus-tagging detection may produce false positives for non-Gmail providers

## How this service works

Email address and email domain verification: syntax check, DNS MX and A records, mail provider detection (Google Workspace, Microsoft 365, ...), disposable/temporary email domain detection, role address detection (info@, admin@, support@), free webmail provider flag, plus-tag detection, SPF and DMARC presence, and a deliverable verdict (likely / risky / no) with the reason. Email validation and list cleaning for signups, CRM and lead qualification. $0.01 per address.

## Output

Returns a structured JSON object containing: syntax validity, DNS MX and A record lookup results, detected mail provider (e.g. Google Workspace, Microsoft 365), disposable/temporary domain flag, role address flag (info@, admin@, support@), free webmail flag, plus-tag detection, SPF presence, DMARC presence, and an overall deliverability verdict (likely / risky / no) with an explanatory reason code.
