```sh
zero fetch --capability exchangerebel-devutils-email-validate-6bae7fab
```

Example prompt: Can you check whether 'john.doe@example.com' is a valid, properly formatted email address before I add it to my mailing list?

## When to prefer this

Choose this endpoint when you need a quick, per-call email validation with a pay-per-use model and no subscription required. Ideal for agents that need lightweight, on-demand email verification integrated into workflows without maintaining a separate email validation service subscription.

## Known failure modes

- Missing or empty email input returns an error
- Malformed query parameters result in a 400 response
