Por exemplo, vamos supor que você possua 4 endpoints na sua API (*operações de rota*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

Você poderia adicionar diferentes requisitos de permissão para cada um deles utilizando apenas dependências e sub-dependências:

```mermaid
graph TB

    * `url` (**обязательно**): `str`-значение с URL-адресом для внешней документации.

### Создание метаданных для тегов { #create-metadata-for-tags }

Давайте попробуем сделать это на примере с тегами для `users` и `items`.

Создайте метаданные для ваших тегов и передайте их в параметре `openapi_tags`:

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

    }
