# Introduction

> Cloud APIs, devices, and device Functions for Orquestr.

# Introduction

Orquestr connects your POS devices to the cloud — invoke adapter functions and automate store operations through a single API.

To get started you'll need:

* An Orquestr organization with an active **license**
* A connected **device** (enrolled via the Device Gateway)
* An **API key**

Then you can list devices and invoke functions such as `sicarv4.products.search`.
