## 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 basebuilder-ecommerce-email-validation-2270ca90 -d '<json body>'
```

Example prompt: Can you check whether 'john.doe@example.com' is a real, deliverable email address — flag it if it looks disposable or invalid so I don't add it to my customer list?

## When to prefer this

Use this endpoint when you need to validate individual email addresses at point-of-entry for an ecommerce or sign-up flow, especially when you want disposable/spam detection combined with format and deliverability checks in a single paid API call via x402 micropayment.

## Known failure modes

- Missing or malformed email input returns a 400 validation error
- Payment not provided or insufficient results in a 402 response
- DNS lookup timeout may cause inconclusive deliverability result
- Temporary email providers may not always be flagged as disposable
- Rate limiting or server errors return 429 or 500 status codes
