En ese caso haría referencia a los atributos del JSON, los tipos de datos que tiene, etc.

#### OpenAPI y JSON Schema

OpenAPI define un schema de API para tu API. Ese schema incluye definiciones (o "schemas") de los datos enviados y recibidos por tu API usando **JSON Schema**, el estándar para los schemas de datos en JSON.

#### Revisa el `openapi.json`

Nesse caso, significaria os atributos JSON e os tipos de dados que eles possuem, etc.

#### OpenAPI e JSON *Schema*

OpenAPI define um *schema* de API para sua API. E esse *schema* inclui definições (ou "*schemas*") dos dados enviados e recebidos por sua API usando **JSON *Schema***, o padrão para *schemas* de dados JSON.

#### Verifique o `openapi.json`

    response.raise_for_status()
    assert response.json() == {
        "name": "valid",
        "date": datetime(2021, 7, 26).isoformat(),

Mit demselben Trick könnten Sie ein Pydantic-Modell verwenden, um das JSON-Schema zu definieren, das dann im benutzerdefinierten Abschnitt des OpenAPI-Schemas für die *Pfadoperation* enthalten ist.

Und Sie könnten dies auch tun, wenn der Datentyp in der Anfrage nicht JSON ist.
