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.
