​
Create an Account

If you don’t have a Novita account, sign up first. For details, please refer to Quickstart guide. New users can complete a quick account setup survey to claim $100 in free Sandbox credits. No credit card is required.

​
Create API Key

Navigate to the Novita Key Management page, create an API key, and save the API key value for use in subsequent steps.

​
Install SDK

You can install the Novita SDK by executing the following commands. 
npm i novita-sandbox

​
Configure Environment Variables

Create a .env file in your project folder if it does not exist, and configure your API key.
For JavaScript and TypeScript projects, you need to import the dotenv/config package in your project; for Python projects, you need to import the dotenv library in your project and call the load_dotenv method to load environment variables. For details, please refer to the example.
.env
NOVITA_API_KEY=sk_*** # Novita API key obtained from previous steps
Or you can configure the API key by setting an environment variable in your terminal.
Bash
export NOVITA_API_KEY=sk_*** # Novita API key obtained from previous steps

​
Use SDK to Start Agent Sandbox

Below is a simple example showing how to create a sandbox, execute code inside it, and list files in the sandbox filesystem. 
// index.ts
import 'dotenv/config'
import { Sandbox } from 'novita-sandbox/code-interpreter'

// The .env file should be located in the project root directory
// dotenv/config will automatically look for .env in the current working directory
// Or 
// You can set the environment variable in the command line
// export NOVITA_API_KEY=sk_***

async function main() {
  const sandbox = await Sandbox.create()
  try {
    const execution = await sandbox.runCode('print("hello world")')
    console.log(execution.logs)

    const files = await sandbox.files.list('/tmp')
    console.log(files)
  } finally {
    // Close sandbox when no longer needed
    await sandbox.kill()
  }
}
main().catch((err) => {
  console.error(err)
  process.exit(1)
})
Execute the following commands to run the code. 
npx tsx ./index.ts
