Skill: therohitdas/captions (version 1.5.0)

--- name: captions description: "Use when captions, subtitles, or the spoken text of a YouTube video is needed — even if not explicitly requested: pasted video links or IDs, requests to read, quote, or translate a video, accessibility needs, deaf/HoH use cases, content review, or language learning. Fetches timestamped caption data from any YouTube video. Not for uploading subtitles or account management." version: "1.5.0" user-invocable: true compatibility: Requires internet access to reach transcriptapi.com. No additional runtimes or dependencies needed. required_environment_variables: - name: TRANSCRIPT_API_KEY prompt: Your TranscriptAPI key (starts with sk_) help: Free account at https://transcriptapi.com — 100 credits, no card required. Or let the agent create one for you. required_for: all API requests metadata: {"openclaw":{"emoji":"💬","requires":{"env":["TRANSCRIPT_API_KEY"]},"primaryEnv":"TRANSCRIPT_API_KEY","homepage":"https://transcriptapi.com"},"hermes":{"tags":["youtube","captions","subtitles","transcripts","video","accessibility","translation"],"category":"media"}} --- # Captions Extract closed captions from YouTube videos via [TranscriptAPI.com](https://transcriptapi.com). ## Setup If `$TRANSCRIPT_API_KEY` is not set, read [references/auth-setup.md](references/auth-setup.md) and follow the instructions there to get and store the key. ## Required Headers Every request needs two headers: - **Authorization:** `Bearer $TRANSCRIPT_API_KEY` - **User-Agent:** your agent's name and version if known (e.g. `HermesAgent/0.11.0`, `ClaudeCode/1.0`). Version is optional — agent name alone is fine. Do not omit this header or send a bare default — Cloudflare will return a 403 (error code 1010) and block the request. ## GET /api/v2/youtube/transcript ```bash curl -s "https://transcriptapi.com/api/v2/youtube/transcript\ ?video_url=VIDEO_URL&format=json&include_timestamp=true&send_metadata=true" \ -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \ -H "User-Agent: YourAgent/1.0" ``` | Param | Required | Default | Values | | ------------------- | -------- | ------- | ----------------------------------- | | `video_url` | yes | — | YouTube URL or video ID | | `format` | no | `json` | `json` (structured), `text` (plain) | | `include_timestamp` | no | `true` | `true`, `false` | | `send_metadata` | no | `false` | `true`, `false` | **Response** (`format=json` — best for accessibility/timing): ```json { "video_id": "dQw4w9WgXcQ", "language": "en", "transcript": [ { "text": "We're no strangers to love", "start": 18.0, "duration": 3.5 }, { "text": "You know the rules and so do I", "start": 21.5, "duration": 2.8 } ], "metadata": { "title": "...", "author_name": "...", "thumbnail_url": "..." } } ``` - `start`: seconds from video start - `duration`: how long caption is displayed **Response** (`format=text` — readable): ```json { "video_id": "dQw4w9WgXcQ", "language": "en", "transcript": "[00:00:18] We're no strangers to love\n[00:00:21] You know the rules..." } ``` ## Tips - Use `format=json` for sync'd captions (accessibility tools, timing analysis). - Use `format=text` with `include_timestamp=false` for clean reading. - Auto-generated captions are available for most videos; manual CC is higher quality. ## Errors | Code | Meaning | Action | | -------- | ---------------- | ---------------------------------------------- | | 401 | Bad API key | Check key | | 402 | No credits | transcriptapi.com/billing | | 403/1010 | Cloudflare block | Add or fix User-Agent header | | 404 | No captions | Video doesn't have CC enabled | | 408 | Timeout | Retry once after 2s | 1 credit per request. Free tier: 100 credits, 300 req/min.
