YouTube API
YouTube data access via TranscriptAPI.com — no Google API quota needed.

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 your shell profile and agent config. Ready to use.
Manual option: transcriptapi.com/signup → Dashboard → API Keys.
