# Hunter Enrich Tool

> Find the emails at a company's domain, and a named person's email, with Hunter

## What it does

For each company, Hunter Enrich returns the emails Hunter has found at its domain, with each person's name, position, seniority and Hunter's confidence. When you include a person's name, it also returns that person's most likely email.

> [!NOTE]
>
> **Requires Hunter Integration**: Set up the [Hunter integration](https://docs.asteragents.com/integrations/hunter) before agents can use this tool.

## What it costs

| Outcome | Hunter searches |
| - | - |
| A domain that returns emails | 1 (repeats in the same billing period are free) |
| A named person found | 1 |
| Nothing found | 0 |

## Parameters

| Parameter | Type | Required | Description |
| - | - | - | - |
| `companies` | array | Yes | Up to 25. Each item: `domain` (preferred) or `company`, plus optional `first_name`, `last_name` or `full_name` |
| `emails_per_domain` | number | No | Emails per domain, 1–100 (default 10) |
| `type` | string | No | `personal` for named people only, `generic` for role inboxes like info@ |
| `seniority` | array | No | `junior`, `senior`, `executive` |
| `department` | array | No | e.g. `executive`, `management` |
| `domain_search` | boolean | No | List the emails at each domain (default `true`). Set `false` to only look up the named person. |

## Tips

* Give a domain whenever you have one. With only a company name, Hunter guesses the domain and often picks a same-name business in another city or country.
* Prefer a named owner or executive; a generic inbox like info@ is the fallback.
* Check addresses with **Verify Emails** before sending.
