# Introduction

> Welcome to Aryn DocParse API Documentation

## Welcome

An interactive specification is accessible by selecting the endpoints on the left. The full text of the Aryn OpenAPI
spec is available for [DocParse](https://github.com/aryn-ai/docs/blob/main/api-reference/endpoint/docparse/openapi.json) and the [Aryn Platform](https://github.com/aryn-ai/docs/blob/main/api-reference/endpoint/platform/openapi.json).

All Aryn APIs require an Aryn API key. You can get one for free at [aryn.ai/get-started](https://www.aryn.ai/get-started)
