All APIs implemented in Webshell are here in Javascript.
in Webshell, you can try all these APIs online in really few lines of code :
apis.google.maps();
This command will search in google folder, pick the last version and execute maps/maps file.
If you have an account on Webshell, you can setup your API Key by creating an apps in your Dashboard. All settings needed are specified in the conf.json file which allow us to generate a form to let you set your API Keys.
Some builtins are used in their APIs are not describe on Webshell.io yet... We work on it ;)
