// Conventions:
// * We use the prefix TF_ for everything in the API.
// * Objects are always passed around as pointers to opaque structs
//   and these structs are allocated/deallocated via the API.
// * TF_Status holds error information.  It is an object type
//   and therefore is passed around as a pointer to an opaque
//   struct as mentioned above.
// * Every call that has a TF_Status* argument clears it on success

En este ejemplo, no declaramos ningún modelo Pydantic. De hecho, el cuerpo del request ni siquiera se <abbr title="converted from some plain format, like bytes, into Python objects">parse</abbr> como JSON, se lee directamente como `bytes`, y la función `magic_data_reader()` sería la encargada de parsearlo de alguna manera.

Sin embargo, podemos declarar el esquema esperado para el cuerpo del request.

ou n'importe quelle autre variation de casse (tout en majuscules, uniquement la première lettre en majuscule, etc.), votre fonction considérera le paramètre `short` comme ayant une valeur booléenne à `True`. Sinon la valeur sera à `False`.
