⚙️ Configuration

Get Your API Key

3. Generate a new API key
4. Copy and save it securely

Set Up Authentication (3 Methods)

Method 1: Environment Variable (Recommended)

export VOICE_AI_API_KEY="your-api-key-here"

Method 2: .env File

# Create .env file in project root
echo 'VOICE_AI_API_KEY=your-api-key-here' >> .env

Method 3: OpenClaw Config

{
  "skills": {
    "voice.ai-voice-agents": {
      "api_key": "your-api-key-here"
    }
  }
}

🔐 Before Any Operation

Important: Always verify authentication before running any commands.

# 1. Check if API key is set
echo $VOICE_AI_API_KEY

# 2. Test connection (list agents)
node scripts/agent.js list

# 3. If errors, re-export your key
export VOICE_AI_API_KEY="your-api-key-here"
