# SDK Overview

## Why use an SDK?

You can call the Typecast API directly over HTTP, but SDKs are recommended for production code. SDKs wrap repetitive integration work such as authentication headers, request and response types, error handling, streaming handling, and response parsing, so you can integrate more safely and faster than implementing every HTTP call yourself. They also provide higher-level workflows such as **voice recommendations**, **text pauses**, and **multi-speaker composition**, which are cumbersome to implement with direct API calls alone.

Use the SDK that matches where your Typecast API integration will run. If you are starting from a script or prototype, Python is usually the fastest path. For production services, choose the SDK that fits your existing backend or app runtime.
