# Introduction

The RateParity API is organized around [REST](http://en.wikipedia.org/wiki/Representational_State_Transfer). Our API has predictable resource-oriented URLs, accepts [form-encoded](https://en.wikipedia.org/wiki/POST_\(HTTP\)#Use_for_submitting_web_forms) request bodies, returns [JSON-encoded](http://www.json.org/) responses, and uses standard HTTP response codes, authentication, and verbs.

If you have a question or any other other request, please contact us at <info@rateparity.com>.
