# API Playground

### Overview

Neurelo's API Playground provides the ability to run and test all of Neurelo Data APIs in a environment. With the playground capability, you can instantly validate your auto generated APIs, extensibility options as well as custom query API endpoints.

### API Docs and Playground for an environment inside a project

{% hint style="info" %}
While using Neurelo's API Playground, it would be faster to keep that environment's specific API Key ready as Neurelo does not store the api keys
