## 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 hunter-domain-search-ac0e4aac -d '<json body>'
```

Example prompt: Find me up to 20 verified email addresses at stripe.com, filtered to senior-level people in the finance department — I only want results that have a full name attached.

## When to prefer this

Use this endpoint when you need to discover multiple email contacts at a specific company or domain in bulk, especially when filtering by department, seniority, or verification status. Prefer this over Email Finder when you don't have a specific person's name and want to explore all available contacts at a domain. Best for prospecting and outreach list building.

## Known failure modes

- Domain not found or no emails indexed — empty results list returned
- Invalid domain format — validation error response
- Invalid filter values (e.g. unrecognized department or seniority) — error or empty results
- Rate limit exceeded — HTTP 429 error
- Authentication failure — HTTP 401 error
- Offset out of range — empty results or error
