# Hunter Prospect Tool

> Find companies by keyword, industry, location and headcount with Hunter Discover

## What it does

Hunter Prospect searches Hunter's company index and returns matching companies with their domain and the number of emails Hunter holds for each. Use it to build a list, then pass the domains to [Hunter Enrich](https://docs.asteragents.com/tools/hunter_enrich.md) to find who to 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

Nothing. Hunter Discover does not use searches.

## Parameters

| Parameter | Type | Required | Description |
| - | - | - | - |
| `query` | string | No | Plain-language search, e.g. "pilates studios in Florida". Hunter reports the filters it inferred. |
| `keywords` | array | No | Company keywords, e.g. `["gym", "yoga studio"]` |
| `keywords_match` | string | No | `any` (default) or `all` |
| `exclude_keywords` | array | No | Keywords to leave out |
| `industries` | array | No | Hunter industry names, e.g. `Wellness and Fitness Services` |
| `locations` | array | No | Headquarters locations, e.g. `[{"country": "US", "state": "FL"}]` |
| `exclude_locations` | array | No | Locations to leave out |
| `headcount` | array | No | Size bands: `1-10`, `11-50`, `51-200` and up |
| `exclude_domains` | array | No | Domains to leave out, e.g. ones already contacted |
| `limit` | number | No | Companies per page, 1–100 (default 100) |
| `offset` | number | No | Page offset, up to 10,000 |

Give a `query` or at least one filter.

## Tips

* Keywords are more precise than industries for a niche. A broad industry like "Wellness and Fitness Services" also returns spas and clinics.
* A keyword like "gyms" can also match software and equipment sellers that serve gyms, so screen the names.
* Use `offset` to page past companies you have already worked.
