# Python SDK Installation

Please use Python version 3.10 or higher to ensure compatibility.

```bash theme={null}
pip install lunary
```

If you want to monitor Anthropic with the official Python SDK, install both packages:

```bash theme={null}
pip install lunary anthropic
```

## Setup

Add the `LUNARY_PUBLIC_KEY` to your environment variables.

```bash theme={null}
export LUNARY_PUBLIC_KEY="PUBLIC KEY"
```

You can use dotenv to load the environment variables from a `.env` file.

```python theme={null}
from dotenv import load_dotenv
load_dotenv()
```
