Existem alguns casos em que pode ser necessário modificar o esquema OpenAPI gerado.

Nesta seção, você verá como fazer isso.

## O processo normal

O processo normal (padrão) é o seguinte:

Uma aplicação (instância) do `FastAPI` possui um método `.openapi()` que deve retornar o esquema OpenAPI.

Como parte da criação do objeto de aplicação, uma *operação de rota* para `/openapi.json` (ou para o que você definir como `openapi_url`) é registrada.

El programa de línea de comandos llamado `fastapi` es **FastAPI CLI**.

FastAPI CLI toma el path de tu programa Python (por ejemplo, `main.py`), detecta automáticamente la `FastAPI` instance (comúnmente llamada `app`), determina el proceso de import correcto, y luego la sirve.

Para producción usarías `fastapi run` en su lugar. 🚀
