# Overview

> Create and manage the knowledge bases your agents retrieve from.

A **knowledge base** (called a `dataset` in the API) is a collection of embedded content that an agent can search to answer questions.

Use these endpoints to:

* **Create**, **update**, and **delete** knowledge bases.
* **List** and **retrieve** them.
* **Query** a knowledge base directly to test retrieval or search from a workflow.

To fill a knowledge base with content, create [Sources](/api-reference/sources/overview) and attach them with [Knowledge base sources](/api-reference/knowledge-base-sources/overview).
