# Context Engine

`context engine`

Use the Context Engine APIs to manage AI Indices, query them with ES|QL, and describe them for an agent. An AI Index attaches a name, sources, traces, and automations to a single data stream or index.

In each space, these APIs return a 404 until the `contextEngine:enabled` advanced setting is turned on for that space.
