# Install the Runpod Serverless SDK

> Install and configure the Serverless SDK for Python, JavaScript, or Go to interact with Serverless endpoints programmatically.

## Python

The Python SDK requires Python 3.10 or higher.

### Install

Create a virtual environment and install the SDK:

<Tabs>
  <Tab title="macOS/Linux">
    ```bash theme={null}
    python3 -m venv venv
    source venv/bin/activate
    pip install runpod
    ```
  </Tab>

  <Tab title="Windows">
    ```bash theme={null}
    python -m venv venv
    venv\Scripts\activate
    pip install runpod
    ```
  </Tab>
</Tabs>

To verify the installation:

```bash theme={null}
python -c "import runpod; print(runpod.__version__)"
```

### Configure your API key

Set your API key as an environment variable and reference it in your code:

```python theme={null}
import runpod
import os

runpod.api_key = os.getenv("RUNPOD_API_KEY")
```

<Warning>
  Never hardcode your API key directly in your code. Always use environment variables or a secrets manager.
</Warning>

For more information, see the [Python SDK on GitHub](https://github.com/runpod/runpod-python).

## JavaScript

The JavaScript SDK supports Node.js and modern JavaScript environments using ES modules.

### Install

```bash theme={null}
npm install --save runpod-sdk
# or
yarn add runpod-sdk
```

### Configure your API key

```javascript theme={null}
import runpodSdk from "runpod-sdk";
const { RUNPOD_API_KEY, ENDPOINT_ID } = process.env;

const runpod = runpodSdk(RUNPOD_API_KEY);
const endpoint = runpod.endpoint(ENDPOINT_ID);
```

For more information, see the [JavaScript SDK on GitHub](https://github.com/runpod/js-sdk) and the [npm package](https://www.npmjs.com/package/runpod-sdk).

## Go

### Install

```bash theme={null}
go get github.com/runpod/go-sdk
go mod tidy
```

### Configure your API key

```go theme={null}
package main

import (
    "os"

    "github.com/runpod/go-sdk/pkg/sdk/config"
    rpEndpoint "github.com/runpod/go-sdk/pkg/sdk/endpoint"
)

func main() {
    apiKey := os.Getenv("RUNPOD_API_KEY")
    endpointId := os.Getenv("ENDPOINT_ID")

    endpoint, err := rpEndpoint.New(
        &config.Config{ApiKey: &apiKey},
        &rpEndpoint.Option{EndpointId: &endpointId},
    )
    if err != nil {
        panic(err)
    }

    // Use the endpoint...
}
```

For more information, see the [Go SDK on GitHub](https://github.com/runpod/go-sdk) and the [Go package documentation](https://pkg.go.dev/github.com/runpod/go-sdk/pkg/sdk).

## Use the SDKs
