## 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`):

```

Example prompt: Can you verify whether john.doe@example.com is a real, valid email address before I add it to my contact list?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002 per call) email verification without needing to manage a dedicated email validation service subscription. Ideal for lightweight integrations, ad-hoc checks, or agents that need occasional email validation as part of a broader workflow. Best suited for single-address verification rather than bulk list cleaning.

## Known failure modes

- Missing or empty email parameter — returns validation error
- Malformed email format — may return invalid status rather than an error
- Network timeout if mail server lookup takes too long
- Rate limiting on free tier for high-volume checks
- Disposable or temporary email domains may return inconsistent results

## Output

Returns a JSON object with an 'ok' boolean indicating whether the email address passed verification. May include additional fields about validity, format correctness, and deliverability status depending on the service tier.
