# Quick Start

> Quick Start Guide for Axon Models

## Prerequisites

1. You need to have a MatterAI account on [https://app.matterai.so](https://app.matterai.so)
2. You need to have API Key for your MatterAI account. You can generate API Key in [https://app.matterai.so/api-keys](https://app.matterai.so/api-keys)

Export an environment variable on macOS or Linux systems

```bash theme={null}
export MATTERAI_API_KEY=YOUR_API_KEY
```

Install the OpenAI SDK and Run an API Call

<CodeGroup>
  ```javascript OpenAI NodeJS SDK theme={null}
  import OpenAI from "openai";

  const openai = new OpenAI({
  apiKey: "MATTERAI_API_KEY",
  baseURL: "https://api.matterai.so/v1",
  });

  async function main() {
  const response = await openai.chat.completions.create({
      "model": "axon",
      "messages": [
          {
              "role": "system",
              "content": "You are a helpful assistant."
          },
          {

  });

  console.log(response.choices[0].message.content);
  }

  main();
  ```
