# 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

**CLI:**

```bash
maton youtube search videos 'coding tutorial' --limit 10
```

```bash
maton api '/youtube/youtube/v3/search?part=snippet&q=coding+tutorial&type=video&maxResults=10'
```

**Python:**

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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://api.maton.ai/youtube/{native-api-path}
```

Maton proxies requests to `www.googleapis.com` and automatically injects your OAuth token.

## Installation

**NPM:**
```bash
npm install -g @maton-ai/cli
```

**Homebrew:**
```bash
brew install maton-ai/cli/maton
```

## Authentication

**CLI:**

```bash
maton login                          # Opens browser for API key
maton login --interactive            # Skip browser, paste API key directly
maton whoami                         # Show current auth state
```

**Manual:**

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key
4. Set your API key as `MATON_API_KEY`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

## Connection Management

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

### List Connections

**CLI:**

```bash
maton connection list youtube --status ACTIVE
```

```bash
maton api -X GET /connections -f app=youtube -f status=ACTIVE
```

**Python:**

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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

**CLI:**

```bash
maton connection create youtube
```

```bash
maton api /connections -f app=youtube
```

**Python:**

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'youtube'}).encode()
req = urllib.request.Request('https://api.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

**CLI:**

```bash
maton connection view {connection_id}
```

```bash
maton api /connections/{connection_id}
```

**Python:**

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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:**
```json
{
  "connection": {
    "connection_id": "{connection_id}",
    "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

**CLI:**

```bash
maton connection delete {connection_id}
```

```bash
maton api -X DELETE /connections/{connection_id}
```

**Python:**

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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:

**CLI:**

```bash
maton youtube channel mine --connection {connection_id}
```

```bash
maton api '/youtube/youtube/v3/channels?part=snippet&mine=true' --connection {connection_id}
```

**Python:**

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If you have multiple connections, always specify the connection to ensure requests go to the intended account.

## Security & Permissions

- Access is scoped to videos, channels, playlists, comments, and captions within the connected YouTube account.
- **All write operations require explicit user approval.** Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

## Pagination

YouTube uses cursor-based pagination via `pageToken`. The CLI automatically paginates with `--paginate`.

Example:

```bash
maton youtube playlist items {playlistId} --paginate
```

## Code Examples

### CLI

```bash
# Search videos as JSON (default format)
maton youtube search videos 'tutorial' --limit 10

# Filter with jq — e.g., extract just video IDs and titles
# Note: --jq requires --json
maton youtube search videos 'tutorial' --limit 10 \
  --json --jq '.items[] | {id: .id.videoId, title: .snippet.title}'

# List your playlists and extract titles only
maton youtube playlist list --json --jq '.items[].snippet.title'
```

### JavaScript

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

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

// Create playlist
await fetch(
  'https://api.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

```python
import os
import requests

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

# Search videos
results = requests.get(
    'https://api.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://api.maton.ai/youtube/youtube/v3/videos',
    headers=headers,
    params={'part': 'snippet,statistics', 'id': 'dQw4w9WgXcQ'}
).json()

# Create playlist
response = requests.post(
    'https://api.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

| Status | Meaning |
|--------|---------|
| 400 | Missing YouTube connection or invalid request |
| 401 | Invalid or missing Maton API key |
| 403 | Forbidden - quota exceeded or insufficient permissions |
| 404 | Video, channel, or playlist not found |
| 429 | Rate limited (10 req/sec per account) |
| 4xx/5xx | Passthrough error from YouTube API |

### Troubleshooting: API Key Issues

**CLI:**

1. Check your auth state:

```bash
maton whoami
```

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

```bash
maton connection list
```

**Manual:**

1. Check that the `MATON_API_KEY` environment variable is set:

```bash
echo $MATON_API_KEY
```

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

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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://api.maton.ai/youtube/youtube/v3/search`
- Incorrect: `https://api.maton.ai/v3/search`
