## 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 strale-email-validator-62e11a07
```

Example prompt: Can you check if 'john.doe@gmial.com' is a real, deliverable email — tell me if the syntax is valid, if MX records exist, whether it's disposable or a role address, and flag any typos in the domain?

## When to prefer this

Choose this endpoint when you need comprehensive email validation beyond simple regex — especially when you want disposable domain detection (5,361 domains), role-address filtering, MX record verification, and typo correction for common providers all in a single call. Ideal for signup flows, lead qualification, and data hygiene pipelines where deliverability confidence matters.

## Known failure modes

- Missing required 'email' parameter returns an error
- Malformed or unparseable email string may return valid:false with no further details
- MX lookup may time out for obscure or slow DNS servers
- Disposable domain list may not cover very recently created throwaway services
- Network errors result in HTTP 5xx responses

## How this service works

Validate an email address: RFC 5322 syntax, MX records, 5,361 disposable domain detection, role-based address detection (35 patterns), free provider detection, and typo suggestion for common providers (gmial.com ? gmail.com). Returns deliverability assess…

## Output

Returns a JSON object with the original email, a boolean validity flag, the domain portion, whether the domain is disposable (checked against 5,361 known domains), whether MX records exist, whether it's a role-based address (35 patterns), and a deliverability assessment. May include a typo suggestion when the domain resembles a common provider.
