# Introduction

> REST API reference for the Supertone TTS platform — endpoints, parameters, and response schemas.

The Supertone API is a RESTful API for generating speech with our voice AI models, browsing the voice library, cloning your own voices, and tracking usage.

This section is the **endpoint reference** — every path, parameter, and response. For tutorials, recipes, and SDK usage, see the [Docs](/en/docs/overview) section instead.

## Base URL
