# API Introduction

This reference section lays out how to extract unstructured data using our AI products. A Sypht AI product is essentially an intelligent model that extracts a collection of fields from a document. We have a whole range of different AI products that meet different business needs. To learn more about our AI products you can contact us [here](https://www.sypht.com/contact).

Before getting started, you'll need to [signup for a Sypht account](https://www.sypht.com/developer). By signing up you'll gain free trial subscriptions to a handful of our AI products out of the box and you'll be granted API credentials that will enable you to generate a `bearerToken` to access the Sypht API.
