# API documentation An API represents the communication capacity between components of one or several software systems and is a set of functions, methods and / or procedures that a library offers that can be accessed through a unique and private key (API KEY) for each client. ### Operation types and methods An operation is a unit of a REST API that you can call. An operation comprises an HTTP verb and a URL path that is subordinate to the context of the API. {% hint style="info" %} Through the API developed by Alephee, you can access different operations, some query (GET) and others that allow the impact of changes on the platform (POST, PUT or DELETE). {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
