# Introduction

The Craft API provides access to the [Craft](https://craft.co/) data platform for developers and data scientists.

You can use this API to access all of our API endpoints, including as the [Company Data API](/company-data-api/introduction.md) to get all company data information and the [Alerts API](/alerts-api/intro.md) to receive alerts on a given company.

The API is organized around GraphQL. All requests should be made over SSL. All request and response bodies, including errors, are encoded in JSON.
