Register an application on Stack Apps
The Stack Exchange API requires a free application key for public read access. Register
an application on Stack Apps to obtain the key.
Sign in to Stack Apps
Sign in to your Stack Exchange account.
- Go to the Stack Apps application registration page.
- If you have registered an application before, the Register an application button no longer appears on this page. Instead, go to Your Apps (or Manage your applications) from the Stack Apps navigation, then use the registration link there, or open an existing application to reuse its app key.

Register an application
On the Your Apps page, click Register an application.

Enter the application details
Complete the Register your application form with your own values. The
following are examples — any name, description, and URL that identify your
