# Complete signup (verify OTP)

`POST /v1/account/verify-otp`

Step 2 of signup. Completes the flow started by POST /v1/account/send-otp. Pass the verificationId from that response and the one-time code from email. On success this creates the trial account and returns a live API key (sk_live_...) plus a companion sandbox API key (sk_test_...) when one was minted. Store both securely — they cannot be retrieved later. First-time users without a key yet must start at send-otp; existing users create extra sandbox keys via POST /v1/api-keys/create-sandbox.
