YouTube Data API

Use the YouTube Data API v3 via direct curl calls to search videos, retrieve video details, get channel information, list playlist items, and fetch comments.

Official docs: https://developers.google.com/youtube/v3

When to Use

Use this skill when you need to:

• Search videos by keywords or filters
• Get video details (title, description, statistics, duration)
• Get channel info (subscriber count, video count, description)
• List playlist items (videos in a playlist)
• Fetch comments on videos
• Get trending videos by region

Prerequisites

1. Create Google Cloud Project

1. Go to Google Cloud Console
2. Create a new project or select existing one
3. Go to "APIs & Services" > "Library"
4. Search for "YouTube Data API v3" and enable it

2. Get API Key

1. Go to "APIs & Services" > "Credentials"
2. Click "Create Credentials" > "API Key"
3. Copy the API key

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

3. (Optional) Restrict API Key

For production use, restrict the key:

• Application restrictions: HTTP referrers, IP addresses
• API restrictions: YouTube Data API v3 only

Important: When using $VAR in a command that pipes to another command, wrap the command containing $VAR in bash -c '...'. Due to a Claude Code bug, environment variables are silently cleared when pipes are used directly. ``bash bash -c 'curl -s "https://api.example.com" -H "Authorization: Bearer $API_KEY" | jq .' ``

Use nextPageToken from response to get more results. Replace <your-next-page-token> with the actual token from the previous response:

Guidelines

1. Quota limits: API has 10,000 units/day quota. Search costs 100 units, most others cost 1 unit
2. Rate limits: Implement exponential backoff on 403/429 errors
3. API key security: Never expose API keys in client-side code
4. Caching: Cache responses to reduce quota usage
5. Video IDs: Extract from URLs like youtube.com/watch?v=VIDEO_ID or youtu.be/VIDEO_ID
