# youtube-apify-transcript

Fetch YouTube transcripts via APIFY API (works from cloud IPs, bypasses YouTube bot detection).

## Why APIFY?

YouTube blocks transcript requests from cloud IPs (AWS, GCP, etc.). APIFY runs the request through residential proxies, bypassing bot detection reliably.

## Free Tier

- **$5/month free credits** (~714 videos)
- No credit card required
- Perfect for personal use

## Cost

- **$0.007 per video** (less than 1 cent!)
- Track usage at: https://console.apify.com/billing

## Links

- [Get API Key](https://console.apify.com/account/integrations)
- [YouTube Transcript Scraper Actor](https://apify.com/pintostudio/youtube-transcript-scraper)

## Setup

1. Create free APIFY account: https://apify.com/
2. Get your API token: https://console.apify.com/account/integrations
3. Set environment variable:

```bash
# Add to ~/.bashrc or ~/.zshrc
export APIFY_API_TOKEN="apify_api_YOUR_TOKEN_HERE"

# Or use .env file (never commit this!)
echo 'APIFY_API_TOKEN=apify_api_YOUR_TOKEN_HERE' >> .env
```

## Usage

### Basic Usage

```bash
# Get transcript as text (uses cache by default)
python3 scripts/fetch_transcript.py "https://www.youtube.com/watch?v=VIDEO_ID"

# Short URL also works
python3 scripts/fetch_transcript.py "https://youtu.be/VIDEO_ID"
```

### Options

```bash
# Output to file
python3 scripts/fetch_transcript.py "URL" --output transcript.txt

# JSON format (includes timestamps)
python3 scripts/fetch_transcript.py "URL" --json

# Both: JSON to file
python3 scripts/fetch_transcript.py "URL" --json --output transcript.json

# Specify language preference
python3 scripts/fetch_transcript.py "URL" --lang de
```

### Caching (saves money!)

Transcripts are cached locally by default. Repeat requests for the same video cost $0.

```bash
# First request: fetches from APIFY ($0.007)
python3 scripts/fetch_transcript.py "URL"

# Second request: uses cache (FREE!)
python3 scripts/fetch_transcript.py "URL"
# Output: [cached] Transcript for: VIDEO_ID

# Bypass cache (force fresh fetch)
python3 scripts/fetch_transcript.py "URL" --no-cache

# View cache stats
python3 scripts/fetch_transcript.py --cache-stats

# Clear all cached transcripts
python3 scripts/fetch_transcript.py --clear-cache
```

Cache location: `.cache/` in skill directory (override with `YT_TRANSCRIPT_CACHE_DIR` env var)

### Batch Mode

Process multiple videos at once:

```bash
# Create a file with URLs (one per line)
cat > urls.txt << EOF
https://youtube.com/watch?v=VIDEO1
https://youtu.be/VIDEO2
https://youtube.com/watch?v=VIDEO3
EOF

# Process all URLs
python3 scripts/fetch_transcript.py --batch urls.txt

# Batch with JSON output to file
python3 scripts/fetch_transcript.py --batch urls.txt --json --output all_transcripts.json
```

## APIFY Actor Input

The script sends the following input to `pintostudio/youtube-transcript-scraper`:

```json
{
  "videoUrl": "https://www.youtube.com/watch?v=VIDEO_ID"
}
```

**Output fields:**

Each result contains a `data` array of transcript segments:

| Field   | Type   | Description                        |
|---------|--------|------------------------------------|
| `start` | number | Segment start time (seconds)       |
| `dur`   | number | Segment duration (seconds)         |
| `text`  | string | Transcript text for this segment   |

### Output Formats

**Text (default):**
```
Hello and welcome to this video.
Today we're going to talk about...
```

**JSON (--json):**
```json
{
  "video_id": "dQw4w9WgXcQ",
  "title": "Video Title",
  "transcript": [
    {"start": 0.0, "dur": 2.5, "text": "Hello and welcome"},
    {"start": 2.5, "dur": 3.0, "text": "to this video"}
  ],
  "full_text": "Hello and welcome to this video..."
}
```
