## 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 basebuilder2-ecommerce-email-validation-7c94efae -d '<json body>'
```

Example prompt: Can you check if the email address john.doe@example.com is valid and actually deliverable before I add it to my mailing list?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call email validation without committing to a subscription service. Well-suited for ecommerce platforms, agent-driven signups, or CRM pipelines where occasional email hygiene checks are needed and cost-per-call billing via USDC is preferred over monthly SaaS contracts.

## Known failure modes

- Invalid or malformed email string returns validation error
- Domain lookup timeout if mail server is unresponsive
- Disposable email provider not in database may be flagged as valid
- Payment failure via x402 protocol returns 402 status
- Rate limiting may occur under high request volume
- Cold domain MX lookup may increase latency
