Yes. Our WordPress plugin lets you shorten links right from the WordPress editor using a simple [shorturl] shortcode, no setup required since your API key comes pre-configured in the download.
To install it, download the plugin file, go to WordPress Admin, then Plugins, then Add New, then Upload Plugin, and upload the provided zip file. Every link created through the shortcode is saved to your account automatically. Since the plugin file contains your personal API key, only install it on sites you control and never share the file with anyone you don't trust.
