## Agregar información extra

Puedes declarar información extra en `Field`, `Query`, `Body`, etc. Y será incluida en el JSON Schema generado.

Aprenderás más sobre cómo agregar información extra más adelante en la documentación, cuando aprendamos a declarar ejemplos.

/// note | Technical Details

It will actually internally create a *path operation* for each *path operation* that was declared in the `APIRouter`.

So, behind the scenes, it will actually work as if everything was the same single app.

You don't have to worry about performance when including routers.

Es wird die Validierung dieser zusammengesetzten Daten übernehmen, und sie im OpenAPI-Schema und der automatischen Dokumentation dokumentieren.

## Einzelne Werte im Body

So wie `Query` und `Path` für Query- und Pfad-Parameter, hat **FastAPI** auch das Äquivalent `Body`, um Extra-Daten für Body-Parameter zu definieren.

**FastAPI** will do the automatic conversion from the request, so that the parameter `item` receives its specific content and the same for `user`.

It will perform the validation of the compound data, and will document it like that for the OpenAPI schema and automatic docs.

## Singular values in body { #singular-values-in-body }

The same way there is a `Query` and `Path` to define extra data for query and path parameters, **FastAPI** provides an equivalent `Body`.
