Validates a single email address for syntax, MX records, disposable/free webmail/role account status, and SPF/DMARC, returning a deliverability verdict with score.

## 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-address-validator-4284a2a5
```

Example prompt: Can you check whether john.doe@example.com is a real, deliverable email address — flag if it's disposable, a role account, or if the domain is missing MX or SPF/DMARC records?

## When to prefer this

Choose this endpoint when you need a single-email, non-sending validation that goes beyond syntax checking — specifically when you need MX verification, disposable/free webmail detection, role account flagging, and SPF/DMARC checks all in one call. Prefer it over basic regex validators when list quality, fraud prevention, or deliverability accuracy matters. It is not a bulk batch validator and does not send a probe email.

## Known failure modes

- Malformed email input returns invalid verdict immediately
- Domain with no MX records returns undeliverable
- Timeout resolving DNS records may return an error or degraded result
- Edge-case international/IDN domains may not resolve correctly
- Known disposable provider lists may lag newly created throwaway domains
- SPF/DMARC check may return partial data if DNS is slow or rate-limited

## How this service works

Validate one email address without sending mail: syntax, MX, disposable, free webmail, role account, SPF/DMARC. Returns deliverable/risky/undeliverable/invalid with score.

## Output

Returns a deliverability verdict (deliverable, risky, undeliverable, or invalid) with a numeric risk score, plus individual signal flags: syntax validity, MX record presence, whether the address is from a disposable provider, a free webmail service, or is a role account (e.g. info@, noreply@), and SPF/DMARC configuration status for the sending domain.
