**FastAPI CLI** is a command line program that you can use to serve your FastAPI app, manage your FastAPI project, and more.

When you install FastAPI (e.g. with `pip install "fastapi[standard]"`), it includes a package called `fastapi-cli`, this package provides the `fastapi` command in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console

**FastAPI CLI** é uma interface por linha de comando do `fastapi` que você pode usar para rodar sua app FastAPI, gerenciar seu projeto FastAPI e mais.

Quando você instala o FastAPI (ex.: com `pip install fastapi`), isso inclui um pacote chamado `fastapi-cli`. Esse pacote disponibiliza o comando `fastapi` no terminal.

Para rodar seu app FastAPI em desenvolvimento, você pode usar o comando `fastapi dev`:

**FastAPI CLI** 是一個命令列程式，能用來運行你的 FastAPI 應用程式、管理你的 FastAPI 專案等。

當你安裝 FastAPI（例如使用 `pip install "fastapi[standard]"`），它會包含一個叫做 `fastapi-cli` 的套件，這個套件提供了 `fastapi` 命令。

要運行你的 FastAPI 應用程式來進行開發，你可以使用 `fastapi dev` 命令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
