YouTube

Access the YouTube Data API v3 with managed OAuth authentication. Search videos, manage playlists, access channel information, and interact with comments and subscriptions.

Quick Start

# Search for videos
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/youtube/youtube/v3/search?part=snippet&q=coding+tutorial&type=video&maxResults=10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://gateway.maton.ai/youtube/{native-api-path}

Replace {native-api-path} with the actual YouTube Data API endpoint path. The gateway proxies requests to www.googleapis.com and automatically injects your OAuth token.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key

Connection Management

Manage your Google OAuth connections at https://ctrl.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=youtube&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Create Connection

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'youtube'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Get Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Response:

{
  "connection": {
    "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "youtube",
    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple YouTube connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/youtube/youtube/v3/channels?part=snippet&mine=true')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

Code Examples

JavaScript

const headers = {
  'Authorization': `Bearer ${process.env.MATON_API_KEY}`
};

// Search videos
const results = await fetch(
  'https://gateway.maton.ai/youtube/youtube/v3/search?part=snippet&q=tutorial&type=video&maxResults=10',
  { headers }
).then(r => r.json());

// Get video details
const video = await fetch(
  'https://gateway.maton.ai/youtube/youtube/v3/videos?part=snippet,statistics&id=dQw4w9WgXcQ',
  { headers }
).then(r => r.json());

// Create playlist
await fetch(
  'https://gateway.maton.ai/youtube/youtube/v3/playlists?part=snippet,status',
  {
    method: 'POST',
    headers: { ...headers, 'Content-Type': 'application/json' },
    body: JSON.stringify({
      snippet: { title: 'My Playlist', description: 'Videos I like' },
      status: { privacyStatus: 'private' }
    })
  }
);

Python

import os
import requests

headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}

# Search videos
results = requests.get(
    'https://gateway.maton.ai/youtube/youtube/v3/search',
    headers=headers,
    params={'part': 'snippet', 'q': 'tutorial', 'type': 'video', 'maxResults': 10}
).json()

# Get video details
video = requests.get(
    'https://gateway.maton.ai/youtube/youtube/v3/videos',
    headers=headers,
    params={'part': 'snippet,statistics', 'id': 'dQw4w9WgXcQ'}
).json()

# Create playlist
response = requests.post(
    'https://gateway.maton.ai/youtube/youtube/v3/playlists?part=snippet,status',
    headers=headers,
    json={
        'snippet': {'title': 'My Playlist', 'description': 'Videos I like'},
        'status': {'privacyStatus': 'private'}
    }
)

Notes

• Video IDs are 11 characters (e.g., dQw4w9WgXcQ)
• Channel IDs start with UC (e.g., UCxyz123)
• Playlist IDs start with PL (user) or UU (uploads)
• Use pageToken for pagination through large result sets
• The part parameter is required and determines what data is returned
• Quota costs vary by endpoint - search is expensive (100 units), reads are cheap (1 unit)
• Some write operations require channel verification
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) to disable glob parsing
• IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

Error Handling

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

2. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with youtube. For example:

• Correct: https://gateway.maton.ai/youtube/youtube/v3/search
• Incorrect: https://gateway.maton.ai/v3/search
