#### Revisa el `openapi.json`

Si sientes curiosidad por saber cómo se ve el schema de OpenAPI en bruto, FastAPI genera automáticamente un (schema) JSON con la descripción de todo tu API.

Le schéma inclut les chemins de votre API, les paramètres potentiels de chaque chemin, etc.

#### "Schéma" de données

Le terme "schéma" peut aussi faire référence à la forme de la donnée, comme un contenu JSON.

Dans ce cas, cela signifierait les attributs JSON, ainsi que les types de ces attributs, etc.

#### OpenAPI et JSON Schema

Esta definição de *schema* inclui as rotas da sua API, os parâmetros possíveis que elas usam, etc.

#### "*Schema*" de dados

O termo "*schema*" também pode se referir à forma de alguns dados, como um conteúdo JSON.

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

* Generate <a href="https://json-schema.org" class="external-link" target="_blank">JSON Schema</a> definitions for your model, you can also use them anywhere else you like if it makes sense for your project.
* Those schemas will be part of the generated OpenAPI schema, and used by the automatic documentation <abbr title="User Interfaces">UIs</abbr>.
