# Introduction

> Overview of the Wave API

The Wave API is a REST API that gives you programmatic access to the Wave Platform. All endpoints are protected — see [Authentication](/api-reference/authentication) to generate your API token. When a request fails, the response body follows the RFC 9457 problem details standard — see [Errors](/api-reference/errors).

The reference is organized in the following groups:
