## Sobre seguridad, APIs y documentación { #about-security-apis-and-docs }

Ocultar las interfaces de usuario de la documentación en producción *no debería* ser la forma de proteger tu API.

Eso no añade ninguna seguridad extra a tu API, las *path operations* seguirán estando disponibles donde están.

Se você quiser desativar completamente o esquema OpenAPI, pode definir `openapi_url=None`, o que também desativará as interfaces de documentação que o utilizam.

## URLs da Documentação { #docs-urls }

Você pode configurar as duas interfaces de documentação incluídas:

* **Swagger UI**: acessível em `/docs`.
    * Você pode definir sua URL com o parâmetro `docs_url`.
