# Subtitles

Fetch YouTube video subtitles via [TranscriptAPI.com](https://transcriptapi.com).

## Setup

If `$TRANSCRIPT_API_KEY` is not set, help the user create an account (100 free credits, no card):

**Step 1 — Register:** Ask user for their email.

```bash
node ./scripts/tapi-auth.js register --email USER_EMAIL
```

→ OTP sent to email. Ask user: _"Check your email for a 6-digit verification code."_

**Step 2 — Verify:** Once user provides the OTP:

```bash
node ./scripts/tapi-auth.js verify --token TOKEN_FROM_STEP_1 --otp CODE
```

> API key saved to your shell profile and agent config. Ready to use.

Manual option: [transcriptapi.com/signup](https://transcriptapi.com/signup) → Dashboard → API Keys.

## GET /api/v2/youtube/transcript

```bash
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_URL&format=text&include_timestamp=false&send_metadata=true" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```

| Param               | Values                  | Use case                                       |
| ------------------- | ----------------------- | ---------------------------------------------- |
| `video_url`         | YouTube URL or video ID | Required                                       |
| `format`            | `json`, `text`          | `json` for sync'd subs with timing             |
| `include_timestamp` | `true`, `false`         | `false` for clean text for reading/translation |
| `send_metadata`     | `true`, `false`         | Include title, channel, description            |

**For language learning** — clean text without timestamps:

```bash
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=text&include_timestamp=false" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```

**For translation** — structured segments:

```bash
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=json&include_timestamp=true" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```

**Response** (`format=json`):

```json
{
  "video_id": "dQw4w9WgXcQ",
  "language": "en",
  "transcript": [
    { "text": "We're no strangers to love", "start": 18.0, "duration": 3.5 }
  ]
}
```

**Response** (`format=text`, `include_timestamp=false`):

```json
{
  "video_id": "dQw4w9WgXcQ",
  "language": "en",
  "transcript": "We're no strangers to love\nYou know the rules and so do I..."
}
```

## Tips

- Many videos have auto-generated subtitles in multiple languages.
- Use `format=json` to get timing for each line (great for sync'd reading).
- Use `include_timestamp=false` for clean text suitable for translation apps.
