--- title: "API A-Z" manual: "TYPO3 Explained" version: "13.4" permalink: "https://docs.typo3.org/permalink/t3coreapi:api@13.4" source: "ApiOverview/Index.rst" rendered: "2026-09-23T17:02:48+00:00" --- # API A-Z {#api} The TYPO3 Core code serves a dual purpose: It functions both as an out-of-the-box application and as a library providing APIs for extensions that enhance projects with additional functionality. The TYPO3 Core itself organizes its code into extensions as well, with the "core" extension offering the majority of API classes. These classes are utilized by other key extensions such as "frontend" and "backend". These three extensions are mandatory for any TYPO3-based project, while others, like "scheduler," are optional. This chapter focuses on the APIs primarily provided by these three essential extensions. TYPO3 APIs are primarily documented within the source code itself. Maintaining documentation in multiple locations is impractical due to the frequent changes in the codebase. This chapter highlights the most critical elements of the API. > [!NOTE] > The source is the documentation!
