Если клиент запросит `http://example.com/items/foo` (`item_id` `"foo"`), то он получит статус-код 200 и ответ в формате JSON:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Но если клиент запросит `http://example.com/items/bar` (несуществующий `item_id` `"bar"`), то он получит статус-код 404 (ошибка "не найдено") и JSON-ответ в виде:

```JSON
{
  "detail": "Item not found"
}
```

#### OpenAPI i JSON Schema

OpenAPI definiuje API Schema dla Twojego API, który zawiera definicje (lub "schematy") danych wysyłanych i odbieranych przez Twój interfejs API przy użyciu **JSON Schema**, standardu dla schematów danych w formacie JSON.

#### Sprawdź `openapi.json`
