kbarbel640-del YouTube API
YouTube data access via TranscriptAPI.com — no Google API quota needed.
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_).
Step 3 — Save: Store the key (auto-configures agent + shell):
node ./scripts/tapi-auth.js save-key --key API_KEY --json
→ Ready to use. Agent runtime picks up the key automatically.
Manual option: transcriptapi.com/signup → Dashboard → API Keys.
