# Email Address Verification

> Email Address Verification is a paid API for AI agents from agents.torbrooknews.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-13).

Verifies an email address by checking syntax validity, domain MX record existence, disposable-domain detection, and role-account flagging.

## 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-verification-cd55d097
```

Example prompt: Can you verify whether 'john.doe@example.com' is a valid, deliverable email address — check if the domain has MX records, and flag it if it's disposable or a role account like info@ or noreply@?

## When to prefer this

Choose this endpoint when you need a lightweight, real-time check on a single email address covering syntax, MX reachability, disposable-domain detection, and role-account flagging — ideal for gating signups, cleaning CRM records, or screening addresses before sending. Prefer this over full SMTP verification when you need a fast, non-intrusive check without actually connecting to a mail server.

## Known failure modes

- Missing or malformed email query parameter returns a 400 error
- Network timeout during MX DNS lookup may return an inconclusive result
- Domains not yet indexed in disposable-domain lists may be missed
- Edge-case valid email formats (IDN, plus-addressing) may be misclassified
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Verify an email address: syntax check, domain MX lookup, disposable-domain and role-account flags. Use before sending or storing an address.

## Output

Returns a structured result indicating whether the email passed syntax validation, whether the domain has valid MX records, whether the domain is on a known disposable-domain list, and whether the local part is a role-based account (e.g. info@, support@, noreply@).
