# Hunter

> Connect Hunter to find companies by keyword, location and size, and the emails at their domains

## Overview

The Hunter integration lets your agents build prospect lists of companies and find who to email at each one. **Hunter Prospect** searches Hunter's company index by keyword, industry, headquarters location and headcount. **Hunter Enrich** returns the emails Hunter has found at a company's domain, with each person's name, position and seniority, and can find a named person's address.

Hunter indexes businesses that have an established website, so it works best for existing small and mid-sized companies. It rarely knows a business that registered in the last few months. For those, pair it with [People Data Labs](https://docs.asteragents.com/integrations/peopledatalabs), which works from a name and home address.

## Prerequisites

* A Hunter account with API access. Any plan works; paid plans can page deeper into Discover results.
* Your Hunter **API key**, from **hunter.io > API**.

## Setup Guide

**1. Get Your API Key**

In Hunter, open **API** and copy your API key.

**2. Connect Hunter in Aster Agents**

Go to **Control Hub > Integrations**, find the **Hunter** card, click **Connect** and paste your API key. Connecting an integration requires org admin.

**3. Add the Tools to Your Agent**

Edit your agent and enable **Hunter Prospect** and **Hunter Enrich**. Pair them with **Verify Emails** so addresses are checked before any outreach.

## Available Tools

* **[Hunter Prospect](https://docs.asteragents.com/tools/hunter_prospect.md)**: find companies by keyword, industry, location and headcount.
* **[Hunter Enrich](https://docs.asteragents.com/tools/hunter_enrich.md)**: find the emails at a company's domain, and a named person's email.
