應用程式介面

應用程式介面（參見英文：API）係一類嘅規格、約定同埋文檔，特徵令某一啲軟件可以透過可重複、可預期嘅方式，去用另一個系統或軟件層所提供嘅資源同功能。呢種介面喺任何軟件之中都會用到，不過可能抽象化咗，終端用家無法直接睇到。應用程式介面有人界定為機制一種，特徵係會定義兩隻軟件之間點樣溝通^[1]。

使用例子

教人工智能玩遊戲，就可以用到應用程式介面。例如 Unity 就有所謂嘅 ML-Agents Toolkit（意即機器學習個體工具箱）可以將 Unity 場景封裝成互動用嘅虛擬環境，俾 Python 端透過應用程式介面去控制 Unity 之中嘅人工智能體—縱使 Unity 預設嘅手稿語言係 C# ^[2]。同時 Python 有套件提供 UnityEnvironment 類別去啟動同連接 Unity 可執行檔或者編輯器^[3]^[4]^[5]。

概念對比

應用程式介面同用家介面（UI）嘅分別包括

面向對象：API 主要係軟件同軟件溝通；用家介面就主要係人同軟件互動。^[6]^[7]
