## 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 hirepulse-b2b-contact-mx-verifier-23b4cf2b -d '<json body>'
```

Example prompt: Can you pull the published contact details and verify the MX records for stripe.com so I know who to reach out to and whether their email is live?

## When to prefer this

Choose this endpoint when you need to find and verify B2B contact information for a specific company domain, especially when you also want to confirm the domain's email infrastructure is live. Priced at $0.01 per call with no charge on empty results, it is cost-effective for batch prospecting. Prefer this over general web scrapers when you specifically need contact extraction combined with MX validation in one call.

## Known failure modes

- Domain not found or unreachable — returns empty result with no charge
- No publicly listed contacts on the domain's pages — empty result returned free
- Invalid domain format — rejected at input validation
- Domain blocks crawling (robots.txt or firewall) — may return partial or no results
- MX record lookup timeout — DNS query failures for certain TLDs
