Vamos começar de onde paramos no capítulo anterior e incrementá-lo.

## Sobre o JWT { #about-jwt }

JWT significa "JSON Web Tokens".

É um padrão para codificar um objeto JSON em uma string longa e densa sem espaços. Ele se parece com isso:

```

```

## Resumen { #recap }

Con `Query`, `Path` (y otros que aún no has visto) puedes declarar metadatos y validaciones de string de las mismas maneras que con [Parámetros de Query y Validaciones de String](query-params-str-validations.md){.internal-link target=_blank}.

Y también puedes declarar validaciones numéricas:

* `gt`: `g`reater `t`han
* `ge`: `g`reater than or `e`qual
