* **`400 - 499`** stehen für „Client error“-Responses („Client-Fehler“). Diese sind die zweithäufigsten, die Sie vermutlich verwenden werden.
    * Ein Beispiel ist `404`, für eine „Not Found“-Response („Nicht gefunden“).
    * Für allgemeine Fehler beim Client können Sie einfach `400` verwenden.

* **`400 - 499`** – статус-коды, сообщающие о клиентской ошибке. Это ещё одна наиболее часто используемая категория.
    * Пример – код `404` для статуса "Not Found".
    * Для общих ошибок со стороны клиента можно просто использовать код `400`.
