# Overview

> Partner integrations for Cartesia TTS and STT in your own app—not Cartesia-hosted agents.

Cartesia provides first-party speech APIs and SDKs, and integrates with many other products and developer frameworks. The pages in this section describe each path at a high level; detailed setup usually lives in partner documentation and repositories.

## Prerequisites

You’ll need these for almost every integration below. Individual pages also list extras (partner accounts, runtimes, SDK installs).

* **[Cartesia API key](https://play.cartesia.ai/keys)** — create and manage keys in the Playground.
* **A voice** — pick one in the Playground or API; see [Choosing a voice](/build-with-cartesia/capability-guides/choosing-a-voice) and [Voice IDs](/build-with-cartesia/tts-models/voice-ids).
