## 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-verification-api-nordman-tehau-98212f3b -d '<json body>'
```

Example prompt: Can you check whether 'john.doe@example.com' is a valid, non-disposable email address with working mail server records?

## When to prefer this

Choose this endpoint when you need a lightweight, per-call email validation that covers syntax, DNS/MX reachability, and disposable-domain detection in a single API call. Ideal for agent workflows that need to gate on email quality before sending communications, storing user data, or importing leads — especially when you want a pay-per-use model without a subscription.

## Known failure modes

- Malformed input (missing email field) returns a 400 error
- DNS timeout or MX resolution failure may result in inconclusive deliverability status
- Disposable domain list may not cover newly created throwaway services
- Valid-looking syntax on a non-existent domain may pass syntax check but fail MX resolution
- Payment failure via x402 protocol results in 402 response before verification occurs

## How this service works

Validate an email address: syntax, MX resolution, disposable-domain check.

## Output

Returns a validation result indicating whether the email address passes syntax checks, whether the domain has valid MX records for mail delivery, and whether the domain is recognized as a disposable or temporary email provider.
