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. ## API Reference Full OpenAPI spec: [transcriptapi.com/openapi.json](https://transcriptapi.com/openapi.json) — consult this for the latest parameters and schemas. ## Video Data (transcript + metadata) — 1 credit ```http GET https://transcriptapi.com/api/v2/youtube/transcript?video_url=VIDEO_URL&format=json&include_timestamp=true&send_metadata=true Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` **Response:** ```json { "video_id": "dQw4w9WgXcQ", "language": "en", "transcript": [ { "text": "We're no strangers to love", "start": 18.0, "duration": 3.5 } ], "metadata": { "title": "Rick Astley - Never Gonna Give You Up", "author_name": "Rick Astley", "author_url": "https://www.youtube.com/@RickAstley", "thumbnail_url": "https://i.ytimg.com/vi/dQw4w9WgXcQ/maxresdefault.jpg" } } ``` ## Video Info & Rich Metadata Check languages before spending a transcript credit (free), or pull view/like counts, publish date, description, duration, and tags (1 credit): ```http GET https://transcriptapi.com/api/v2/youtube/info?video_url=VIDEO_URL Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` ```http GET https://transcriptapi.com/api/v2/youtube/video/metadata?video_url=VIDEO_URL&include=details,related Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` `video/metadata` returns `title`, `viewCountText`, `likeCountText`, `publishDate`, `description`, `descriptionLinks`, `channel`, `thumbnails`, plus `details` (duration, category, tags, caption tracks) and `related` videos when requested via `include`. > **Naming:** `/video/metadata` was previously `/video/info`. The old path still works but is deprecated. ## Search Data — 1 credit/page ```http GET https://transcriptapi.com/api/v2/youtube/search?q=QUERY&type=video&limit=20 Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` `type` also accepts `playlist` and `movie`. First page only, you can add `sort` (`relevance`/`views`), `upload_date` (`hour`/`today`/`week`/`month`/`year`), `duration` (`short`/`medium`/`long`), and `features` (e.g. `hd,subtitles,cc`). **Video result fields:** `videoId`, `title`, `channelId`, `channelTitle`, `channelHandle`, `channelVerified`, `lengthText`, `viewCountText`, `publishedTimeText`, `hasCaptions`, `thumbnails` **Channel result fields** (`type=channel`): `channelId`, `title`, `handle`, `url`, `description`, `subscriberCount`, `verified`, `rssUrl`, `thumbnails` ## Channel Data Channel endpoints accept `channel` — an `@handle`, channel URL, or `UC...` ID. No need to resolve first. **Resolve handle to ID (free):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/resolve?input=@TED Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns: `{"channel_id": "UCsT0YIqwnpJCM-mx7-gSA4Q", "resolved_from": "@TED"}` **Latest 15 videos with exact stats (free):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/latest?channel=@TED Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns: `channel` info, `results` array with `videoId`, `title`, `published` (ISO), `viewCount` (exact number), `description`, `thumbnail` **All channel videos (paginated, 1 credit/page):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/videos?channel=@NASA&tab=videos Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 # Most-viewed first (channel Videos tab, ~30 per page) GET https://transcriptapi.com/api/v2/youtube/channel/videos?channel=@NASA&sort=popular Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns ~100 videos per page + `continuation_token` for pagination. `tab` also accepts `shorts` or `streams`, and you repeat the same `tab` when paginating. **Sorting.** Add sort=latest, popular, or oldest to channel/videos to get a channel's videos in the order you want, for example its most-popular uploads first. A sorted page returns about 30 videos (an unsorted page returns about 100), and every page costs the same 1 credit. When paging, send the same sort on each request. **Item fields.** Every item carries `members_only`, `true` only when YouTube badges it "Members only", and those items have no `viewCountText`. `tab=streams` items carry `lengthText` and `publishedTimeText` (for example `Streamed 2 years ago`); `tab=shorts` returns `null` for both, because YouTube's Shorts grid publishes neither. On the channel-tab feeds (`tab=videos` with `sort`, `tab=shorts`, `tab=streams`) `channelId`, `channelTitle`, `channelHandle` and `index` are `null`. **Search within channel (1 credit):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/search?channel=@TED&q=QUERY&limit=30 Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` **Channel profile (1 credit):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/info?channel=@TED Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns: `title`, `handle`, `verified`, `subscriberCountText`, `videoCountText`, `description`, `tags`, `thumbnails`, `banners`, `availableTabs` **Channel playlists (1 credit/page):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/playlists?channel=@TED Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns: `results` (`playlistId`, `title`, `url`, `videoCountText`, `thumbnails`), `continuation_token`, `has_more` **Channel community posts (1 credit/page):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/posts?channel=@TED Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns: `results` (`postId`, `authorName`, `text`, `publishedTimeText`, `voteCountText`, `attachment`), `continuation_token`, `has_more` **Channel curated sections (1 credit):** ```http GET https://transcriptapi.com/api/v2/youtube/channel/sections?channel=@TED Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns shelves of videos/playlists/shorts/featured channels, in the channel's own order. `tab` also accepts `podcasts` or `releases`. ## Playlist Data — 1 credit/page Accepts `playlist` — a YouTube playlist URL or playlist ID. ```http GET https://transcriptapi.com/api/v2/youtube/playlist/videos?playlist=PL_ID Authorization: Bearer $TRANSCRIPT_API_KEY User-Agent: YourAgent/1.0 ``` Returns: `results` (videos), `playlist_info` (`title`, `numVideos`, `ownerName`, `viewCount`), `continuation_token`, `has_more` ## Credit Costs | Endpoint | Cost | Data returned | | ----------------- | -------- | ------------------------------- | | transcript | 1 | Full transcript + metadata | | info | **free** | Basic metadata + languages | | video/metadata | 1 | Rich metadata (+ details/related) | | search | 1/page | Video/channel/playlist/movie details | | channel/resolve | **free** | Channel ID mapping | | channel/info | 1 | Channel profile | | channel/latest | **free** | 15 videos + exact stats | | channel/videos | 1/page | ~100/page unsorted, ~30/page sorted | | channel/search | 1 | Videos matching query | | channel/playlists | 1/page | Channel's playlists | | channel/posts | 1/page | Community tab content | | channel/sections | 1 | Curated home-page shelves | | playlist/videos | 1/page | 100 videos per page | ## 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 | Not found | Resource doesn't exist | | 408 | Timeout | Retry once | | 422 | Validation error | Check param format | Free tier: 100 credits, 300 req/min. ## Copy-paste examples Every request in this file as a ready-to-run one-liner: [references/curl-examples.md](https://skilld.dev/api/skills-raw/zeropointrepo/youtube-skills/youtube-data/references/curl-examples.md)
