# TranscriptAPI Full YouTube data toolkit via [TranscriptAPI.com](https://transcriptapi.com). Transcripts, search, channels, playlists — one API key. ## 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, generate a secure password. ```bash node ./scripts/tapi-auth.js register --email USER_EMAIL --password SECURE_PASS --json ``` → OTP sent to email. Ask user: _"Check your email for a 6-digit verification code."_ ⚠️ **SAVE THE PASSWORD** — you need it again in Step 2! **Step 2 — Verify:** Once user provides the OTP (use SAME password from Step 1): ```bash node ./scripts/tapi-auth.js verify --email USER_EMAIL --password SECURE_PASS --otp CODE --json ``` → Returns `api_key` (starts with `sk_`). **Step 3 — Save:** Store the key (auto-configures agent + shell): ```bash node ./scripts/tapi-auth.js save-key --key API_KEY --json ``` → Ready to use. Agent runtime picks up the key automatically. Manual option: [transcriptapi.com/signup](https://transcriptapi.com/signup) → Dashboard → API Keys. ## Auth All requests: `-H "Authorization: Bearer $TRANSCRIPT_API_KEY"` ## Endpoints ### GET /api/v2/youtube/transcript — 1 credit ```bash curl -s "https://transcriptapi.com/api/v2/youtube/transcript\ ?video_url=VIDEO_URL&format=text&include_timestamp=true&send_metadata=true" \ -H "Authorization: Bearer $TRANSCRIPT_API_KEY" ``` | Param | Required | Default | Validation | | ------------------- | -------- | ------- | ------------------------------- | | `video_url` | yes | — | YouTube URL or 11-char video ID | | `format` | no | `json` | `json` or `text` | | `include_timestamp` | no | `true` | `true` or `false` | | `send_metadata` | no | `false` | `true` or `false` | Accepts: `https://youtube.com/watch?v=ID`, `https://youtu.be/ID`, `youtube.com/shorts/ID`, or bare `ID`. **Response** (`format=json`): ```json { "video_id": "dQw4w9WgXcQ", "language": "en", "transcript": [ { "text": "We're no strangers...", "start": 18.0, "duration": 3.5 } ], "metadata": { "title": "...", "author_name": "...", "author_url": "..." } } ``` ### GET /api/v2/youtube/search — 1 credit ```bash curl -s "https://transcriptapi.com/api/v2/youtube/search?q=QUERY&type=video&limit=20" \ -H "Authorization: Bearer $TRANSCRIPT_API_KEY" ``` | Param | Required | Default | Validation | | ------- | -------- | ------- | --------------------- | | `q` | yes | — | 1-200 chars (trimmed) | | `type` | no | `video` | `video` or `channel` | | `limit` | no | `20` | 1-50 | **Response** (`type=video`): ```json { "results": [ { "type": "video", "videoId": "dQw4w9WgXcQ", "title": "Rick Astley - Never Gonna Give You Up", "channelId": "UCuAXFkgsw1L7xaCfnd5JJOw", "channelTitle": "Rick Astley", "channelHandle": "@RickAstley", "channelVerified": true, "lengthText": "3:33", "viewCountText": "1.5B views", "publishedTimeText": "14 years ago", "hasCaptions": true, "thumbnails": [{ "url": "...", "width": 120, "height": 90 }] } ], "result_count": 20 } ``` **Response** (`type=channel`): ```json { "results": [ { "type": "channel", "channelId": "UCuAXFkgsw1L7xaCfnd5JJOw", "title": "Rick Astley", "handle": "@RickAstley", "subscriberCount": "4.2M subscribers", "verified": true, "rssUrl": "https://www.youtube.com/feeds/videos.xml?channel_id=UC..." } ], "result_count": 5 } ``` ### GET /api/v2/youtube/channel/resolve — FREE (0 credits) ```bash curl -s "https://transcriptapi.com/api/v2/youtube/channel/resolve?input=@mkbhd" \ -H "Authorization: Bearer $TRANSCRIPT_API_KEY" ``` | Param | Required | Validation | | ------- | -------- | --------------------------------------- | | `input` | yes | 1-200 chars — @handle, URL, or UC...
