# Zinin M2M Hub Email Verifier

> Zinin M2M Hub Email Verifier is a paid API for AI agents from api.timzinin.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-30).

Validates email addresses by checking syntax, MX records, disposability, and role-account status to determine deliverability

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 zinin-m2m-hub-email-verifier-2e77cc01 -d '<json body>'
```

Example prompt: Can you verify whether test@gmail.com is a real, deliverable email address — check its syntax, MX records, whether it's disposable, and if it's a role account?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email validation that goes beyond syntax checking to include MX record lookup, disposable email detection, and role account flagging — without requiring a subscription. Ideal for agents validating individual addresses on demand rather than batch list processing.

## Known failure modes

- Invalid or malformed email format returns syntax error verdict
- Domain with no MX records returns mxFound: false
- Network timeout on DNS lookup may return incomplete results
- Payment failure (x402) results in no response if USDC balance insufficient
- Catch-all domains cannot confirm individual mailbox existence so mailboxChecked remains false

## How this service works

Pay-per-call data & tool APIs

## Output

Returns a JSON object with a results array containing per-email details: syntax validity, MX record presence and list, deliverability verdict (e.g. 'valid_syntax_and_mx'), detected email provider, disposable flag, role account flag, catch-all risk, domain resolution status, mailbox check status, and timestamp. Meta includes run time and item count.
