## 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 taskmill-email-verification-e20e2709 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 per call) single email address validation before storing user data, sending communications, or onboarding new users. Prefer this when you want a simple pass/fail or validity score on individual email addresses without needing bulk batch validation tools.

## Known failure modes

- Invalid or missing email parameter returns an error
- Malformed email strings may return invalid without deeper lookup
- Network timeouts if the verification provider is unreachable
- Disposable or temporary email services may yield uncertain results
- Private or obscure domains may return inconclusive deliverability results

## How this service works

Taskmill operates specialized service desks and API-native machines that turn research and execution into accountable outcomes.

## Output

Returns a validation result indicating whether the provided email address is valid, including signals about deliverability, format correctness, and whether the address is likely real or disposable/fake.
