## 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 disposable-email-check-d2884c32
```

Example prompt: Can you check whether the email address 'user@mailinator.com' is a disposable or throwaway address, and tell me if it's actually deliverable?

## When to prefer this

Choose this endpoint when you need a lightweight, per-address disposable/temporary email check that also covers free webmail classification, role address detection, and MX presence in a single call. Ideal for signup fraud prevention, lead qualification, and email list hygiene workflows where you pay only $0.01 per check and need a fast deliverability verdict without running your own DNS lookups or maintaining disposable domain lists.

## Known failure modes

- Missing or malformed email address parameter returns an error
- Unknown or newly created disposable domains may not be flagged if not in the database
- MX lookup failures due to DNS timeouts may affect the deliverability verdict
- Legitimate custom domains that happen to share patterns with disposable providers may be incorrectly flagged

## How this service works

Disposable / temporary email detection: is this address or domain a throwaway (Mailinator, Guerrilla Mail, 10minutemail, YOPmail...), a free webmail provider (Gmail, Outlook...), or a role address (info@, admin@)? Includes MX presence and a deliverability verdict. Signup fraud prevention and list hygiene. $0.01 per address.

## Output

Returns a JSON object indicating whether the email is from a known disposable/temporary provider (e.g. Mailinator, Guerrilla Mail, 10minutemail, YOPmail), whether it is a free webmail provider (e.g. Gmail, Outlook), whether it is a role address (e.g. info@, admin@), whether valid MX records exist for the domain, and an overall deliverability verdict.
