## 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 email-office-at-domain-2afdca68
```

Example prompt: Can you check whether office@acme.com is a real, deliverable email address — I want to know if it has valid MX records, whether it's a disposable or free provider, and what the overall deliverability verdict is?

## When to prefer this

Use this endpoint when you need a fast, low-cost check on whether the standard office@ role address for a domain is reachable, without actually sending an email. Ideal for pre-qualifying business contacts, enriching CRM data, or validating leads at scale. Prefer this over generic email verifiers when you specifically need the office@ role address and want SPF/DMARC context alongside deliverability.

## Known failure modes

- Domain does not exist or has no MX records — verdict returned as 'no' with reason
- Invalid domain format supplied — syntax error returned
- Domain uses a disposable or free-provider mail service — flagged accordingly with risky or no verdict
- Transient DNS lookup failure — may return an error or retry-required response
- Rate limiting or payment failure at $0.01 per call — HTTP 402 returned

## How this service works

Does office@<domain> look deliverable? Builds the office@ address for the domain you give and runs the verifier: syntax, MX presence, mail provider, disposable/free-provider flags, SPF/DMARC presence and a deliverable/risky/no verdict with the reason (mailbox existence is not probed). Fast way to find a working office contact. $0.01 per check.

## Output

Returns a deliverability verdict (deliverable, risky, or no) with a reason, along with MX record presence, identified mail provider name, flags for disposable and free-provider addresses, and SPF/DMARC presence — all for the office@ address of the supplied domain. Mailbox existence is not probed.
