# Using Key-Value Cache API

Use the GridGain key-value cache API to perform basic cache operations, work with binary objects, and run scan and index queries.

This section describes how to work with GridGain data through the key-value cache API, including basic cache operations, binary objects and their schemas, and scan and index queries.
