Example Usage

Ask your AI agent:

"Create a temporary email, sign up for example.com, and get me the verification code"

The agent will:

1. Call create_inbox → gets test123@tempyx.com

2. Use the email to sign up on the website

3. Call wait_for_otp → waits for the verification email

4. Return the OTP code to you
