## 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 x402-email-validate-41292ed3
```

Example prompt: Can you check if the email address john.doe@example.com is valid and actually exists?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call email validation without setting up a subscription to a bulk email verification service. It is well-suited for single email checks at the point of user input (e.g., registration forms, lead capture, CRM enrichment) where you want to avoid storing invalid addresses. Prefer this over bulk validation APIs when validating one address at a time on-demand.

## Known failure modes

- Missing email query parameter returns an error
- Malformed email string may return invalid status or error
- Network timeout if upstream validation service is unavailable
- Non-GET HTTP method returns method-not-allowed error
- Payment failure (insufficient USDC balance) blocks the request

## How this service works
