## 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 saylor-innovations-email-validator-494bf352
```

Example prompt: Can you check whether 'john.doe@gmial.com' is a valid, deliverable email address — I want to know if the syntax is correct, if it has working MX records, whether it's a disposable address, and if there are any obvious typos?

## When to prefer this

Choose this endpoint when you need a lightweight, fast, multi-factor email validation that covers syntax, DNS/MX checks, disposable domain detection, role-address flagging, and typo correction in a single call. Ideal for pre-registration checks, CRM hygiene, and marketing list filtering where you want actionable verdicts with explanatory reasons rather than a binary pass/fail.

## Known failure modes

- Missing or empty email query parameter returns an error
- Malformed email string may return invalid_syntax with no MX check
- Disposable domain list may not cover all throwaway providers
- MX lookup may time out for slow DNS responses
- Non-existent TLDs or domains return invalid verdict

## How this service works

Email Address Validation (syntax, MX, disposable, role, typos) — Data Validation

## Output

A JSON object containing the submitted email, a boolean valid_syntax field, a verdict string (e.g. 'valid', 'invalid', 'risky'), and a reasons array listing specific issues found such as typos, disposable domain, missing MX records, or role-based address detection.
