# Runway Install Auth

## Overview

Install the Runway ML SDK and configure API key authentication for AI video generation.

## Prerequisites

- Runway account at runwayml.com
- API key from the Runway Developer Portal (dev.runwayml.com)
- Python 3.9+ or Node.js 18+

## Instructions

### Step 1: Install SDK

```bash
set -euo pipefail
# Python
pip install runwayml

# Node.js
npm install @runwayml/sdk
```

### Step 2: Configure Environment

```bash
# .env
RUNWAYML_API_SECRET=key_xxxxxxxxxxxxxxxxxxxxxxxx
```

### Step 3: Verify Connection (Python)

```python
from runwayml import RunwayML

client = RunwayML()  # Reads RUNWAYML_API_SECRET from env

# The client is ready — no explicit auth call needed
# SDK auto-authenticates on first API call
print("RunwayML client initialized")
```

### Step 4: Verify Connection (Node.js)

```typescript
import RunwayML from '@runwayml/sdk';

const runway = new RunwayML();  // Reads RUNWAYML_API_SECRET from env
console.log('RunwayML client initialized');
```

## Output

- `runwayml` SDK installed
- API key configured via environment variable
- Client ready for video generation

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| `401 Unauthorized` | Invalid API key | Verify key at dev.runwayml.com |
| `ModuleNotFoundError` | SDK not installed | `pip install runwayml` |
| `RUNWAYML_API_SECRET not set` | Missing env var | Set in .env or export |
