# Email Verify

> Email Verify is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Validates an email address with syntax, live DNS (MX/A) checks, and detection of disposable, role-based, and consumer mailboxes, returning a GO/HOLD/STOP verdict with reasons.

## 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-verify-b6c631b8
```

Example prompt: Can you check whether john.doe@gmial.com is a legitimate email address — specifically whether it's disposable, a role account, or has a domain typo — and give me a GO, HOLD, or STOP verdict?

## When to prefer this

Choose this endpoint when you need a fast, lightweight email quality gate that combines syntax checking, live DNS resolution, disposable domain detection, and role-account flagging in a single call — without the complexity or deliverability risks of an SMTP probe. Ideal for pre-signup screening, lead enrichment, or pre-send validation where you want a clear actionable verdict (GO/HOLD/STOP) rather than raw DNS data. Not suitable if you need to confirm actual mailbox existence.

## Known failure modes

- Missing or malformed email query parameter — returns error indicating required field
- DNS lookup timeout or transient failure — may result in uncertain or degraded verdict
- Unknown or brand-new disposable domain not yet in blocklist — may return GO incorrectly
- Legitimate role-style addresses at small businesses may be flagged as HOLD incorrectly
- Rate limiting or payment failure — returns 402 or 429 status

## How this service works

Syntax + live DNS (MX/A) + disposable, role and consumer-mailbox detection, as one GO / HOLD / STOP verdict with the reasons listed. Catches throwaway inboxes, support@-style shared mailboxes and one-character domain typos (gmial.com). No SMTP probe, so mailbox existence is not claimed.

## Output

Returns a structured verdict of GO, HOLD, or STOP for the given email address, along with a list of reasons explaining the verdict. Reasons may include syntax errors, missing or invalid MX/A DNS records, detection as a known disposable domain, identification as a role-based address (e.g. support@, admin@), or a likely one-character domain typo. Does not confirm mailbox existence as no SMTP probe is performed.
