# Alemba API Architecture

The API fits within the ASM Core architecture, and typically looks as illustrated in the diagram below.

With the installation, you get:

* Alemba.Web, containing:
  * Authorization service – allows you to login and provides a token to use for all subsequent API calls
  * The API Explorer which is an interactive UI for understanding the API, including live search facilities as well as detailed technical information regarding all the available entities and actions
* Alemba.API – the main API
* The Alemba API also provides many new tables of metadata in the ASM database.
