### Модели для входа и выхода в документации { #model-for-input-and-output-in-docs }

Если посмотреть все доступные схемы (JSON Schema) в OpenAPI, вы увидите две: `Item-Input` и `Item-Output`.

Для `Item-Input` поле `description` **не является обязательным** — красной звёздочки нет.

А для `Item-Output` `description` **обязательно** — красная звёздочка есть.
