## 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 coockies-ai-email-validation-d6186f47 -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 our mailing list?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call email validation without a subscription, especially in agent-driven workflows on Base chain using x402 micropayments. Ideal for one-off or low-volume validation tasks where a subscription-based service is overkill.

## Known failure modes

- Missing or malformed email address input returns an error
- Unresolvable domains may be flagged as invalid even if the address is legitimate
- Temporary DNS failures could cause false negatives on valid addresses
- Rate limiting may occur if too many validations are requested rapidly
- Disposable email detection may produce false positives for obscure legitimate providers
