## Using the same dependency multiple times { #using-the-same-dependency-multiple-times }

If one of your dependencies is declared multiple times for the same *path operation*, for example, multiple dependencies have a common sub-dependency, **FastAPI** will know to call that sub-dependency only once per request.

* `/items/`
* `/items/{item_id}`

...como pretendíamos.

* Serán marcados con una lista de tags que contiene un solo string `"items"`.
  * Estos "tags" son especialmente útiles para los sistemas de documentación interactiva automática (usando OpenAPI).
* Todos incluirán las `responses` predefinidas.
* Todas estas *path operations* tendrán la lista de `dependencies` evaluadas/ejecutadas antes de ellas.
