# YouTube Full
Complete YouTube toolkit via [TranscriptAPI.com](https://transcriptapi.com). Everything in one skill.
## 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 `~/.openclaw/openclaw.json`. See **File Writes** below for details. Existing file is backed up before modification.
Manual option: [transcriptapi.com/signup](https://transcriptapi.com/signup) → Dashboard → API Keys.
## File Writes
The verify and save-key commands save the API key to `~/.openclaw/openclaw.json` (sets `skills.entries.transcriptapi.apiKey` and `enabled: true`). **Existing file is backed up to `~/.openclaw/openclaw.json.bak` before modification.**
To use the API key in terminal/CLI outside the agent, add to your shell profile manually:
`export TRANSCRIPT_API_KEY=<your-key>`
## API Reference
Full OpenAPI spec: [transcriptapi.com/openapi.json](https://transcriptapi.com/openapi.json) — consult this for the latest parameters and schemas.
## 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 | Values |
| ------------------- | -------- | ------- | ------------------------------- |
| `video_url` | yes | — | YouTube URL or 11-char video ID |
| `format` | no | `json` | `json`, `text` |
| `include_timestamp` | no | `true` | `true`, `false` |
| `send_metadata` | no | `false` | `true`, `false` |
**Response** (`format=json`):
```json
{
"video_id": "dQw4w9WgXcQ",
"language": "en",
"transcript": [{ "text": "...", "start": 18.0, "duration": 3.5 }],
"metadata": { "title": "...", "author_name": "...", "author_url": "..." }
}
```
## Search — 1 credit
```bash
# Videos
curl -s "https://transcriptapi.com/api/v2/youtube/search?q=QUERY&type=video&limit=20" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
# Channels
curl -s "https://transcriptapi.com/api/v2/youtube/search?q=QUERY&type=channel&limit=10" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
| Param | Required | Default | Validation |
| ------- | -------- | ------- | ------------------ |
| `q` | yes | — | 1-200 chars |
| `type` | no | `video` | `video`, `channel` |
| `limit` | no | `20` | 1-50 |
## Channels
All channel endpoints accept `channel` — an `@handle`, channel URL, or `UC...` channel ID. No need to resolve first.
### Resolve handle — FREE
```bash
curl -s "https://transcriptapi.com/api/v2/youtube/channel/resolve?input=@TED" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
Response: `{"channel_id": "UC...", "resolved_from": "@TED"}`
### Latest 15 videos — FREE
```bash
curl -s "https://transcriptapi.com/api/v2/youtube/channel/latest?channel=@TED" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
Returns exact `viewCount` and ISO `published` timestamps.
### All channel videos — 1 credit/page
```bash
# First page (100 videos)
curl -s "https://transcriptapi.com/api/v2/youtube/channel/videos?channel=@NASA" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
# Next pages
curl -s "https://transcriptapi.com/api/v2/youtube/channel/videos?continuation=TOKEN" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
Provide exactly one of `channel` or `continuation`. Response includes `continuation_token` and `has_more`.
### Search within channel — 1 credit
```bash
curl -s "https://transcriptapi.com/api/v2/youtube/channel/search\
?channel=@TED&q=QUERY&limit=30" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
## Playlists — 1 credit/page
Accepts `playlist` — a YouTube playlist URL or playlist ID.
```bash
# First page
curl -s "https://transcriptapi.com/api/v2/youtube/playlist/videos?playlist=PL_ID" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
# Next pages
curl -s "https://transcriptapi.com/api/v2/youtube/playlist/videos?continuation=TOKEN" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
Valid ID prefixes: `PL`, `UU`, `LL`, `FL`, `OL`. Response includes `playlist_info`, `results`, `continuation_token`, `has_more`.
## Credit Costs
| Endpoint | Cost |
| --------------- | -------- |
| transcript | 1 |
| search | 1 |
| channel/resolve | **free** |
| channel/latest | **free** |
| channel/videos | 1/page |
| channel/search | 1 |
| playlist/videos | 1/page |
## Validation Rules
| Field | Rule |
| ---------- | ------------------------------------------------------- |
| `channel` | `@handle`, channel URL, or `UC...` ID |
| `playlist` | Playlist URL or ID (`PL`/`UU`/`LL`/`FL`/`OL` prefix) |
| `q` | 1-200 chars |
| `limit` | 1-50 |
## Errors
| Code | Meaning | Action |
| ---- | ---------------- | ------------------------------------- |
| 401 | Bad API key | Check key |
| 402 | No credits | transcriptapi.com/billing |
| 404 | Not found | Resource doesn't exist or no captions |
| 408 | Timeout | Retry once after 2s |
| 422 | Validation error | Check param format |
| 429 | Rate limited | Wait, respect Retry-After |
## Typical Workflows
**Research workflow:** search → pick videos → fetch transcripts
```bash
# 1. Search
curl -s "https://transcriptapi.com/api/v2/youtube/search\
?q=machine+learning+explained&limit=5" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
# 2. Transcript
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=text&include_timestamp=true&send_metadata=true" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
**Channel monitoring:** latest (free) → transcript
```bash
# 1. Latest uploads (free — pass @handle directly)
curl -s "https://transcriptapi.com/api/v2/youtube/channel/latest?channel=@TED" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
# 2. Transcript of latest
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=text&include_timestamp=true&send_metadata=true" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY"
```
Free tier: 100 credits, 300 req/min. Starter ($5/mo): 1,000 credits.

// TranscriptAPI CLI — Passwordless Account Setup (ClawHub Edition)
//
// Minimal version for ClawHub registry. Only writes to ~/.openclaw/openclaw.json.
// For shell RC writes, use the standard version in skills/*/scripts/tapi-auth.js.
//
// Authentication flow:
// 1. User provides email → server creates account and returns a short-lived
// session token (JWT, expires in ~30 min). No password is involved.
// 2. Server sends a one-time 6-digit verification code to the email.
// 3. User provides the code → server verifies and returns an API key.
// 4. API key is saved to ~/.openclaw/openclaw.json for agent runtime access.

tapi-auth.js v${VERSION} - TranscriptAPI Account Setup (ClawHub Edition)
Creates a TranscriptAPI account and sets up an API key. No passwords
are involved — the server sends a one-time verification code to your
email, and once verified, the API key is saved to the OpenClaw config
(~/.openclaw/openclaw.json) for agent runtime access.
For terminal/CLI usage, manually add to your shell profile:
export TRANSCRIPT_API_KEY=<your-key>
USAGE:
1. Register: node ./scripts/tapi-auth.js register --email USER_EMAIL
→ Sends a 6-digit code to your email. Returns a session token.
→ Ask user: "Check your email for a 6-digit verification code."
2. Verify: node ./scripts/tapi-auth.js verify --token TOKEN --otp CODE
→ Verifies the code, saves API key to OpenClaw config. Done.
COMMANDS:
register Create account, sends verification code --email (required), --name
verify Verify code, auto-save API key --token, --otp
get-key Retrieve existing API key --token
save-key Manually save an API key --key
status Check account status --token
FLAGS:
--human Human-readable output (default is JSON)
