## 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 role-mailbox-classification-for-vendor-screening-76b24152 -d '<json body>'
```

Example prompt: Can you check if support@acmesupplies.com is a role-based mailbox — like a shared inbox rather than a real person's address?

## When to prefer this

Choose this endpoint when you need a lightweight, read-only check to determine if an email is a generic role-based address (support@, billing@, admin@) as part of vendor screening or contact quality workflows. It is ideal when you cannot send a verification email and need a fast, DNS-only signal. Prefer it over full email verification services when you specifically need role mailbox classification rather than deliverability checks.

## Known failure modes

- Invalid email format returns a validation error
- Unresolvable or non-existent domain may return an inconclusive or error response
- Uncommon or non-standard role names may not be detected if outside the known classification set
- Network or DNS lookup failures may result in a timeout or service error

## How this service works

Role mailbox classification for Vendor screening: Identify common role-based mailbox names such as support or billing. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns a classification indicating whether the queried email address corresponds to a common role-based mailbox name (e.g. support, billing, admin, noreply). The result is derived purely from DNS-level data and does not confirm inbox existence or send any messages.
