## 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 blackbobs-ai-email-validation-2642a7e5 -d '<json body>'
```

Example prompt: Can you check if john.doe@example.com is a real, deliverable email address before we add it to our mailing list?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call email validation without committing to a subscription-based service. Ideal for validating individual email addresses on-demand in agent workflows, form submissions, or CRM hygiene tasks where batch validation services are overkill.

## Known failure modes

- Invalid or missing email address input returns an error
- Unreachable mail server may cause inconclusive deliverability result
- Payment failure via x402 on Base chain blocks the request
- Timeout when checking MX records for obscure domains
- Disposable email detection may have false positives for newer providers

## How this service works

## Output

Returns a validation result object indicating whether the email address is syntactically correct, whether the domain exists, whether the mailbox is deliverable, and potentially flags for disposable or role-based addresses.
