In the output, there's a line with something like:

```hl_lines="4"
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

That line shows the URL where your app is being served on your local machine.

### Check it { #check-it }

Open your browser at [http://127.0.0.1:8000](http://127.0.0.1:8000).

You will see the JSON response as:

```JSON
{"message": "Hello World"}
```

Dans la sortie, il y a une ligne semblable à :

```hl_lines="4"
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

Cette ligne montre l’URL où votre application est servie, sur votre machine locale.

### Vérifier { #check-it }

Ouvrez votre navigateur à l’adresse [http://127.0.0.1:8000](http://127.0.0.1:8000).

Vous verrez la réponse JSON suivante :

```JSON
{"message": "Hello World"}

/// tip

The IP `0.0.0.0` is commonly used to mean that the program listens on all the IPs available in that machine/server.

The docs UI would also need the OpenAPI schema to declare that this API `server` is located at `/api/v1` (behind the proxy). For example:

```JSON hl_lines="4-8"
{
    "openapi": "3.1.0",
