# Introduction

> Turn any IP address into company intelligence with the Snitcher IP to Company API. Real-time company identification for B2B applications.

<Warning>
  **Please Note:** The IP to Company API is a standalone offering and is not included with our standard product plans. If you'd like to purchase or learn more,
  please <a id="start-intercom-survey">answer a few quick questions</a> so our team can reach out.
</Warning>

## What is IP to Company?

**IP to Company is a real-time API that identifies which company an IP address belongs to.** Send us an IP address, and we'll return detailed firmographic data including company name, industry, size, location, and social profiles.

Use it to enrich your application with company intelligence—personalize experiences, qualify leads, route support tickets, or power your own visitor identification features.

## How It Works

The API is simple: send an IP address, receive company data.

```

### Single Request, Rich Response

```bash theme={null}
curl -X POST 'https://api.snitcher.com/company/find?ip=203.0.113.42' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Accept: application/json'
```

When we identify a company, you'll receive:

| Data               | Example                   |
| ------------------ | ------------------------- |
| **Company Name**   | Acme Corporation          |
| **Domain**         | acme.com                  |
| **Industry**       | Information Technology    |
| **Employee Range** | 50-200 employees          |
| **Annual Revenue** | $10M - $50M               |
| **Location**       | San Francisco, CA, USA    |
| **LinkedIn**       | linkedin.com/company/acme |

<Tip>
  The API returns a `type` field indicating whether the IP belongs to a `business`, `isp`, or other network type—so you can handle each case appropriately.

### Two Ways to Identify

You can look up a company by **IP address**, or—if you also run [Radar](/powered-by-snitcher/radar/introduction)—by a visitor's **session ID** for a higher match rate. See the [Quickstart](/powered-by-snitcher/ip2company/quickstart#input-methods) for both input methods and when to use each.
