YouTube channel tools via 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.

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:

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 → 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 — consult this for the latest parameters and schemas.

All channel endpoints accept flexible input — @handle, channel URL, or UC... channel ID. No need to resolve first.

GET /api/v2/youtube/channel/resolve — FREE

Convert @handle, URL, or UC... ID to canonical channel ID.

curl -s "https://transcriptapi.com/api/v2/youtube/channel/resolve?input=@TED" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY"

Response:

{ "channel_id": "UCsT0YIqwnpJCM-mx7-gSA4Q", "resolved_from": "@TED" }

If input is already UC[a-zA-Z0-9_-]{22}, returns immediately.

GET /api/v2/youtube/channel/latest — FREE

Latest 15 videos via RSS with exact stats.

curl -s "https://transcriptapi.com/api/v2/youtube/channel/latest?channel=@TED" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY"

Great for monitoring channels — free and gives exact view counts + ISO timestamps.

GET /api/v2/youtube/channel/videos — 1 credit/page

Paginated list of ALL channel uploads (100 per page).

# First page
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, not both.

Response:

  "results": [{
    "videoId": "abc123xyz00",
    "title": "Video Title",
    "channelId": "UCsT0YIqwnpJCM-mx7-gSA4Q",

curl -s "https://transcriptapi.com/api/v2/youtube/channel/search\
?channel=@TED&q=climate+change&limit=30" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY"

Typical workflow

# 1. Check 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. Get transcript of recent video
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"

Errors

Free tier: 100 credits, 300 req/min. Free endpoints (resolve, latest) require auth but don't consume credits.
