# YouTube Channel Monitor (AssemblyAI)

Monitor YouTube channels and auto-transcribe new videos using AssemblyAI cloud API. Zero local dependencies beyond `requests`.

Prerequisites

1. **AssemblyAI account**: https://www.assemblyai.com/app/signup (free, 100 hours/month)

2. **API Key**: from Dashboard

3. **`requests`** library (usually pre-installed with OpenClaw/Python)

Setup API Key

Choose one:

# Option A: environment variable
export ASSEMBLYAI_API_KEY="your-key"

# Option B: config file
echo '{"api_key": "your-key"}' > data/config.json

How It Works

Channel page → innertube API → audio direct URL → AssemblyAI cloud → text + summary

No local audio download, no Whisper, no ffmpeg. AssemblyAI handles everything server-side.

Commands

# Transcribe a single video
python3 scripts/monitor.py now "https://www.youtube.com/watch?v=VIDEO_ID"

# Add a channel to monitor
python3 scripts/monitor.py add "https://www.youtube.com/@ChannelName/videos" "Alias"

# Check all channels for new videos + transcribe
python3 scripts/monitor.py check [count_per_channel]

# List channels
