To add it to your *path operation*, declare it the same way you declared path and query parameters:

...and declare its type as the model you created, `Item`.

With just that Python type declaration, **FastAPI** will:

* Read the body of the request as JSON.
* Convert the corresponding types (if needed).
* Validate the data.
