YouTube Data

YouTube data access via TranscriptAPI.com — lightweight alternative to Google's YouTube Data API.

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>
