Notice that you can use Markdown inside of the descriptions, for example "login" will be shown in bold (**login**) and "fancy" will be shown in italics (_fancy_).

/// tip

You don't have to add metadata for all the tags that you use.

///

### Use your tags { #use-your-tags }

* `title`: The OpenAPI title, shown in the docs.
* `version`: The version of your API, e.g. `2.5.0`.
* `openapi_version`: The version of the OpenAPI specification used. By default, the latest: `3.1.0`.
* `summary`: A short summary of the API.
* `description`: The description of your API, this can include markdown and will be shown in the docs.

# Response – Statuscode ändern { #response-change-status-code }

Sie haben wahrscheinlich schon vorher gelesen, dass Sie einen Default-[Response-Statuscode](../tutorial/response-status-code.md) festlegen können.

In manchen Fällen müssen Sie jedoch einen anderen als den Default-Statuscode zurückgeben.

## Anwendungsfall { #use-case }

Stellen Sie sich zum Beispiel vor, Sie möchten standardmäßig den HTTP-Statuscode „OK“ `200` zurückgeben.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,
    APIKeyHeader,

    /**
     * Notification message displayed on the login page.
     * This message is shown to users on the authentication page.
     */
    @Size(max = 3000)
    public String notificationLogin;

    /**
     * Notification message displayed on the search top page.
     * This message is shown to users on the main search page.
     */
    @Size(max = 3000)
    public String notificationSearchTop;

Schon bevor **JSON Schema** `examples` unterstützte, unterstützte OpenAPI ein anderes Feld, das auch `examples` genannt wurde.

Diese **OpenAPI-spezifischen** `examples` finden sich in einem anderen Abschnitt der OpenAPI-Spezifikation. Sie sind **Details für jede *Pfadoperation***, nicht für jedes JSON-Schema.

## Documentation Response description - OpenAPI { #documentation-response-description-openapi }

To define the description of the response, shown in the docs UI, read the docs for [Tutorial - Path Operation Configurations - Response description](../tutorial/path-operation-configuration.md#response-description).

 *       }
 *     };
 * iteratorTester.test();
 * iteratorTester.testForEachRemaining();

 *
 * <p><b>Note</b>: It is necessary to use {@code IteratorTester.KnownOrder} as shown above, rather
 * than {@code KnownOrder} directly, because otherwise the code cannot be compiled.
