Output Formats

All commands default to JSON output, save to file with --output parameter.

# Output to file
python ~/.claude/skills/youtube-data-api/scripts/youtube_api.py search \
    --query "Python" \
    --output results.json

# CSV format (tabular data)
python ~/.claude/skills/youtube-data-api/scripts/youtube_api.py search \

python ~/.claude/skills/youtube-data-api/scripts/youtube_api.py search \
    --query "Python" \
    --all-pages \
    --max-total 500 \
    --output all_results.json

Error Handling

Common Error Codes

Code	Description	Solution
400	Bad request	Check parameter format
401	Unauthorized	Check API Key
403	Quota exceeded or insufficient permissions	Check quota or request increase
404	Resource not found	Verify ID is correct
429	Too many requests	Reduce request frequency

Quota Optimization Tips

1. Use fields parameter to request only needed fields
2. Batch requests using comma-separated ID lists
3. Cache results to avoid duplicate requests
4. Use ETags to check if resource has been updated

# Only get needed fields (reduces response size)
python ~/.claude/skills/youtube-data-api/scripts/youtube_api.py video \
    --id "VIDEO_ID" \
    --fields "items(id,snippet(title,channelTitle),statistics(viewCount))"

Operations Requiring OAuth

The following operations require user authorization (API Key alone is not sufficient):

• Upload videos
• Update video metadata
• Delete videos
• Manage playlists
• Post/delete comments
• Download captions
• Access user private data

For these operations, configure OAuth 2.0 client:

# Setup OAuth (first time use)
python ~/.claude/skills/youtube-data-api/scripts/youtube_api.py auth \
    --client-secrets client_secrets.json

---

Installing Dependencies

# Install Python dependencies
pip install google-api-python-client google-auth-oauthlib

# Optional: Install yt-dlp (for subtitle downloading)
pip install yt-dlp

---

Quick Check

# Check if API key is valid
python ~/.claude/skills/youtube-data-api/scripts/youtube_api.py test

# Check quota usage
python ~/.claude/skills/youtube-data-api/scripts/youtube_api.py quota
