# Introduction

## What is Channel3?

Channel3 is building a database of every product on the internet.

Developers use the Channel3 API to build AI shopping apps and agents. Whether you're creating a smart recommendation engine, a visual search tool, an agent that purchases products autonomously, or something totally new, Channel3 can power it.

## What can you do with Channel3?

### Find almost any product on the internet

Search for furniture, fashion, electronics — whatever you can think of — with text, images, or both.

> **Note**
>
> Channel3 supports locale-aware search for physical products, starting with the U.S. and expanding across select international markets. Coverage outside the U.S. may be limited at first. Please [contact us](mailto:support@trychannel3.com) if you're looking for a specific geography.

### Earn commission on sales

We've partnered with thousands of brands who pay us when we drive them sales. We take a cut and pay you the rest.

### Track prices over time

Subscribe to products and get notified when prices change. Build deal alerts, price history charts, or smart buying recommendations for your users.
