## 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 zyvrox-email-validation-d9870f4f
```

Example prompt: Can you check whether the email address 'johndoe@acmecorp.com' is real and deliverable — I want to know if it has valid MX records and whether it's a disposable address?

## When to prefer this

Choose this endpoint when you need pay-per-use, no-subscription email validation with disposable address detection and MX record verification returned in a single structured response. Ideal for agents that only occasionally validate emails and want to avoid monthly subscription costs. Useful for signup fraud prevention, CRM hygiene, and pre-send deliverability checks where real-time results are required.

## Known failure modes

- Malformed email input may return valid:false without detailed diagnostics
- Disposable provider databases may be outdated, causing false negatives
- MX record checks depend on DNS availability and may time out
- Payment failure (402) if USDC balance is insufficient on Base mainnet
- Cold/new domains may have MX records but not be truly deliverable

## How this service works

Enterprise SOCKS5 proxy pool (540K+ proxies, 146 countries) and real-time email validation. Pay per use in USDC on Base mainnet. No subscription required.

## Output

Returns a JSON object with the validated email address, a boolean indicating overall validity, whether MX records were found for the domain, whether the address belongs to a known disposable/temporary email provider, and whether the address is considered deliverable.
