## 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 validate-agentutil-net-26b8440f -d '<json body>'
```

Example prompt: Can you check if 'john.doe+test@mailinator.com' is a real, valid email address or a disposable throwaway — and give me the normalized version?

## When to prefer this

Use this endpoint when you need to quickly validate a single email address, detect throwaway/disposable addresses to prevent spam signups, or normalize an email before storing or sending — especially in agent workflows where real-time validation at point-of-entry is needed.

## Known failure modes

- Missing or empty email field returns a validation error
- Malformed JSON body returns a 400 error
- Invalid or unreachable endpoint returns a 402 or 5xx error
- Edge-case email formats (e.g. internationalized domains) may produce uncertain results

## How this service works

Validate an email address with disposable detection and normalization

## Output

Returns a validation result indicating whether the email is valid, whether it comes from a known disposable/temporary email provider, and the normalized form of the address.
