 To support any application big or small, KittyCAD's functionality is broken up into many individual services, called endpoints. This is our API, and it allows developers to build in only the functionality they need, and leave out whatever they don’t.
 
-You may build a file converter app just using our [convert](https://zoo.dev/docs/api/file/convert-cad-file-with-defaults) API endpoint, while someone building a full-featured CAD suite may use our [design endpoints](https://zoo.dev/docs/api/modeling/open-a-websocket-which-accepts-modeling-commands) to let their users generate 3D models through a traditional user interface. Both these developers got only the features they needed, and both haven't had to think about the complexities of CAD file formats, [rendering engines](https://zoo.dev/geometry-engine), or most of the other thorny problems of building hardware design tools. That's what KittyCAD is for.

 TL;DR Text-to-CAD transforms text into editable CAD models, distinct from 3D meshes by generating B-Rep surfaces for compatibility with CAD programs.
 ### Getting Started
-To use the Text-to-CAD Blender add-on, users need to have [Blender](https://www.blender.org/) installed and acquire an [API token from Zoo.dev](https://zoo.dev/account/api-tokens). The add-on is straightforward to set up and use, making the transition from concept to CAD model smoother and faster than traditional methods.

 ### Key Features
 - **Easy Integration**: Fits smoothly into the native Blender workflow of installing add-ons and includes a keyboard shortcut.
 - **Multiple Formats**: Supports various output formats, catering to different project requirements. The files generated by this plugin and Text-to-CAD are always available from your [dashboard](https://text-to-cad.zoo.dev/dashboard).
