## 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 paygentic-email-validator-62cc8c53
```

Example prompt: Can you validate this email address for me — john.doe@example.com — check both that the format is correct and that the domain actually accepts email?

## When to prefer this

Choose this endpoint when you need lightweight, fast email verification combining both format validation and DNS-level domain reachability (MX record check) without sending a real email. Ideal for pre-validation of user-submitted emails in registration flows, CRM cleanup, or pre-campaign list hygiene. Prefer this over pure regex-based checks since it also confirms the domain can actually receive mail.

## Known failure modes

- Missing or empty 'e' query parameter returns an error
- Malformed email address causes syntax check to fail immediately
- Domain has no MX records — valid syntax but undeliverable domain
- DNS timeout or network error during MX lookup
- Rate limiting if too many requests in a short period

## How this service works

Email validation: syntax check plus MX lookup for the domain. Input: e.

## Output

Returns a validation result indicating whether the email address passes syntax checks and whether the email's domain has valid MX records, confirming the domain can receive email.
