# Installation

> Step-by-step guide to installing the Orynt SDK and configuring your environment.

# 📦 Installing the Orynt SDK

The Orynt SDK is distributed via npm and works in both **Node.js** and browser environments.

> [Orynt SDK on npm](https://www.npmjs.com/package/@orynt/ai-x402)

***

## 1️⃣ Install via npm

```bash theme={null}
npm add @orynt/ai-x402
```

Or, if you use yarn:

```bash theme={null}
yarn add @orynt/ai-x402
```

Or, if you use pnpm:

```bash theme={null}
pnpm add @orynt/ai-x402
```

***

## 2️⃣ Set Up Environment Variables

To authenticate with the SDK, set your wallet private key in a `.env` file:

```bash theme={null}
PRIVATE_KEY=<your_wallet_private_key>
```

> Keep your private key secure and do not commit it to version control.

***

## 3️⃣ SDK Configuration Example

```javascript theme={null}
import { Orynt } from "@orynt/ai-x402";

const ai = new Orynt({
  baseUrl: "https://api.oryntai.xyz/api/v1",
  network: "solana-devnet" // select your network
});
```

* **baseUrl**: API endpoint for Orynt requests
* **network**: blockchain network for micropayments
* **privateKey**: your wallet key for authentication and payments

***

## 4️⃣ Verification

After setup, you can test your installation by making a simple chat request:

```javascript theme={null}
const response = await ai.chat({
  model: "gpt-4.1",
  messages: [{ role: "user", content: "Hello!" }],
});

console.log(response);
```

You should receive a valid AI response if the installation and environment variables are correctly configured.
