The `status_code` parameter receives a number with the HTTP status code.

/// info

`status_code` can alternatively also receive an `IntEnum`, such as Python's <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

It will:

First, copy the public key block below into a new file called `gradle_pubkey.asc`, then import it with this command:

```bash
gpg --import gradle_pubkey.asc
```

Alternatively, you can fetch the key directly from a key server:

```bash
gpg --keyserver hkps://keys.openpgp.org --recv-keys 1BD97A6A154E7810EE0BC832E2F38302C8075E3D
```

### Verifying signatures

```sh
go install github.com/minio/minio@latest
```

You can alternatively run `go build` and use the `GOOS` and `GOARCH` environment variables to control the OS and architecture target.
For example:

```
env GOOS=linux GOARCh=arm64 go build
```

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

Alternatively, if you don't have a way to provide a command line option like `--root-path` or equivalent, you can set the `root_path` parameter when creating your FastAPI app:
