    misleading; it was always used to configure redirects between `https://` and
    `http://` schemes.

    routes have failed but this is no exposed in the API.

### Same Schema for Input and Output Models in Docs { #same-schema-for-input-and-output-models-in-docs }

And now there will be one single schema for input and output for the model, only `Item`, and it will have `description` as **not required**:

### Gleiches Schema für Eingabe- und Ausgabemodelle in der Dokumentation { #same-schema-for-input-and-output-models-in-docs }

Und jetzt wird es ein einziges Schema für die Eingabe und Ausgabe des Modells geben, nur `Item`, und es wird `description` als **nicht erforderlich** kennzeichnen:

### JSON Schema's `examples` field { #json-schemas-examples-field }

But then JSON Schema added an <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a> field to a new version of the specification.

And then the new OpenAPI 3.1.0 was based on the latest version (JSON Schema 2020-12) that included this new field `examples`.

Благодаря этой возможности **Pydantic v2** документация вашего API становится более **точной**; если у вас есть сгенерированные клиенты и SDK, они тоже будут точнее, с лучшим **удобством для разработчиков** и большей консистентностью. 🎉

## Не разделять схемы { #do-not-separate-schemas }

### Modelo para Entrada e Saída na Documentação { #model-for-input-and-output-in-docs }

E se você verificar todos os Schemas disponíveis (JSON Schemas) no OpenAPI, verá que há dois, um `Item-Input` e um `Item-Output`.

# Separación de Esquemas OpenAPI para Entrada y Salida o No { #separate-openapi-schemas-for-input-and-output-or-not }

Al usar **Pydantic v2**, el OpenAPI generado es un poco más exacto y **correcto** que antes. 😎

De hecho, en algunos casos, incluso tendrá **dos JSON Schemas** en OpenAPI para el mismo modelo Pydantic, para entrada y salida, dependiendo de si tienen **valores por defecto**.

Veamos cómo funciona eso y cómo cambiarlo si necesitas hacerlo.

### JSON Schemas Feld `examples` { #json-schemas-examples-field }

Aber dann fügte JSON Schema ein <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>-Feld zu einer neuen Version der Spezifikation hinzu.

Und dann basierte das neue OpenAPI 3.1.0 auf der neuesten Version (JSON Schema 2020-12), die dieses neue Feld `examples` enthielt.
