IP Address API

The WhatIsMyIP.com IP API (Application Programming Interface) gives you access to most of our tools programmatically. You have to be a registered member to access the Application Programming Interface. Bronze and Silver Members get one API key with 24 and 120 calls per day, respectively. Gold level accounts get ten separate keys. Gold level keys are allowed 1,440 calls per day (one per minute) for a total of 14,400 calls per day (ten per minute).

Go to your account page to complete key generation and management. API URLs are shown within the API Quick Start Guide and the API Full Documentation, which can be found from your account page.

  • Get IP Address – Outputs your IP address
