# App with SDK

If you're building an app, the SDK is the best way to integrate Channel3.

## Option A — Coding agent + skill

```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
npx skills add channel3-ai/skills --skill channel3-api
```

Optional UI (React + shadcn):

```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
npx shadcn@latest add https://ui.trychannel3.com/r/all.json
```

Then prompt:

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
Build a shopping experience using the Channel3 skill, Channel3 SDK, and Channel3 UI components. Top: text and image search with filters. Results in a grid; click opens a PDP with variants, similar products, and a way back.
```

## Option B — Manual setup

**1. Create an account**

[Sign up](https://trychannel3.com/sign-up), then copy a key from [API
keys](https://trychannel3.com/dashboard/api).

**2. Install the SDK**

See [SDK](/sdk.md) for TypeScript and Python install and a first
`products.search` call.

**3. Read the response**

Price and buy links are on **offers** — start with [What you
get](/guides/response-overview.md).

## Commissions

Authenticated requests attribute buy links to your key. We've partnered with thousands of brands who pay commissions on those sales.
