## 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 genexxis-email-validator-49e6cccf
```

Example prompt: Can you validate the email address florence.nightingale@yopmail.com and tell me if it's actually deliverable, whether it's a disposable address, and if there are any typos or MX record issues?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal email validation (syntax + MX + disposable + role + free provider + typo suggestion + verdict) in a single call without SMTP probing. It supports up to 50 addresses per call at a flat rate, making it cost-effective for bulk hygiene. Prefer it over basic regex validators when you need actionable deliverability verdicts with reasons, or over SMTP-probing services when you want non-intrusive validation.

## Known failure modes

- Missing both email and emails query parameters — returns an error response
- More than 50 addresses in the comma-separated emails list — likely rejected or truncated
- Malformed comma-separated list — may cause partial or error response
- Network or DNS lookup timeout for MX records — may return degraded verdict
- Unusual or internationalized domain names — MX resolution may be unreliable

## How this service works

Validates one email (email=) or up to 50 (emails=comma list, same price): RFC 5322 syntax, normalized form, MX records (A fallback), disposable, role account, free provider, typo suggestion, and a deliverable/risky/undeliverable verdict with reasons. No SMTP probing.

## Output

A JSON object per email containing: normalized email form, domain, syntax validity, MX record status and records, disposable flag, role account flag, free provider flag, typo suggestion (or null), a verdict of 'deliverable'/'risky'/'undeliverable', and an array of reason codes explaining the verdict.
