## Recapitulando

Com `Query`, `Path` (e outras que você ainda não viu) você pode declarar metadados e validações de texto do mesmo modo que com [Parâmetros de consulta e validações de texto](query-params-str-validations.md){.internal-link target=_blank}.

E você também pode declarar validações numéricas:

* `gt`: maior que (`g`reater `t`han)
* `ge`: maior que ou igual (`g`reater than or `e`qual)
* `lt`: menor que (`l`ess `t`han)

## Install FastAPI

The first step is to install FastAPI.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then **install FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>
