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

Vor OpenAPI 3.1.0 verwendete OpenAPI eine ältere und modifizierte Version von **JSON Schema**.

JSON Schema hatte keine `examples`, daher fügte OpenAPI seiner eigenen modifizierten Version ein eigenes `example`-Feld hinzu.

OpenAPI fügte auch die Felder `example` und `examples` zu anderen Teilen der Spezifikation hinzu:
