# Installation

## JavaScript / TypeScript

```bash
npm install @elevenlabs/elevenlabs-js
```

> **Important:** Always use `@elevenlabs/elevenlabs-js`. The old `elevenlabs` npm package (v1.x) is deprecated and should not be used.

```javascript
import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js";

// Option 1: Environment variable (recommended)
// Set ELEVENLABS_API_KEY in your environment
const client = new ElevenLabsClient();

// Option 2: Pass directly
const client = new ElevenLabsClient({ apiKey: "your-api-key" });
```

### Migrating from deprecated packages

If you have old packages installed, remove them:

```bash
# Remove deprecated packages
npm uninstall elevenlabs

# Install the current packages
npm install @elevenlabs/elevenlabs-js

# For client-side/browser usage, also install:
npm install @elevenlabs/client  # Browser client
npm install @elevenlabs/react   # React hooks
```

**Import changes:**
```javascript
import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js";
import { Scribe } from "@elevenlabs/client";
import { useScribe } from "@elevenlabs/react";
```

## Python

```bash
pip install elevenlabs
```

```python
from elevenlabs.client import ElevenLabs

# Option 1: Environment variable (recommended)
# Set ELEVENLABS_API_KEY in your environment
client = ElevenLabs()

# Option 2: Pass directly
client = ElevenLabs(api_key="your-api-key")
```

## cURL / REST API

Set your API key as an environment variable:

```bash
export ELEVENLABS_API_KEY="your-api-key"
```

Include in requests via the `xi-api-key` header:

```bash
curl -X POST "https://api.elevenlabs.io/v1/speech-to-text" \
  -H "xi-api-key: $ELEVENLABS_API_KEY" \
  -F "file=@audio.mp3" \
  -F "model_id=scribe_v2"
```
