## 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 whatchuneed-email-validate-126e361e -d '<json body>'
```

Example prompt: Can you check if 'john.doe@example.com' is a valid, deliverable email address?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call email validation without setting up a dedicated email verification service subscription. It is ideal for low-to-medium volume validation needs within an agent workflow that already uses the whatchuneed API gateway for other utilities.

## Known failure modes

- Missing or empty input field returns an error
- Malformed request body causes 400-level response
- Network timeout or upstream service unavailability
- Payment failure via x402 protocol prevents call from completing
- Ambiguous or borderline email formats may return uncertain results
