Extract closed captions from YouTube videos 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, generate a secure password.

node ./scripts/tapi-auth.js register --email USER_EMAIL --password SECURE_PASS --json

→ OTP sent to email. Ask user: "Check your email for a 6-digit verification code." ⚠️ SAVE THE PASSWORD — you need it again in Step 2!

Step 2 — Verify: Once user provides the OTP (use SAME password from Step 1):

node ./scripts/tapi-auth.js verify --email USER_EMAIL --password SECURE_PASS --otp CODE --json

→ Returns api_key (starts with sk_).

Store the key (auto-configures agent + shell):
