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, in your local machine.

### Check it { #check-it }

Open your browser at <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>.

You will see the JSON response as:

```JSON

///

/// tip | Astuce

Pour ceux qui se demandent, "AlexNet", "ResNet", et "LeNet" sont juste des noms de <abbr title="Techniquement, des architectures de modèles">modèles</abbr> de Machine Learning.

### Déclarer un paramètre de chemin

Créez ensuite un *paramètre de chemin* avec une annotation de type désignant l'énumération créée précédemment (`ModelName`) :

*----+------+------+
| <<<maven.repo.local>>> | The repository on the local machine Maven shall use to store installed and downloaded artifacts (POMs, JARs, etc). | <<<$\{user.home\}/.m2/repository>>> |
*----+------+------+

        if (q20.ans != null) {
            return q20.ans;
        }
        throw q1x.uhe;
    }

    /**
     * Determines the address of a host given it's host name. The name can be a
     * machine name like "jcifs.samba.org",  or an IP address like "192.168.1.15".
     *
     * @param hostname NetBIOS or DNS hostname to resolve
     * @throws java.net.UnknownHostException if there is an error resolving the name
     */

server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// 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",

   *
   * @since 8.0
   */
  public static final byte NUL = 0;

  /**
   * Start of Heading: A communication control character used at the beginning of a sequence of
   * characters which constitute a machine-sensible address or routing information. Such a sequence
   * is referred to as the "heading." An STX character has the effect of terminating a heading.
   *
   * @since 8.0
   */
  public static final byte SOH = 1;

### Конкурентность + параллелизм: Веб + Машинное обучение { #concurrency-parallelism-web-machine-learning }

С **FastAPI** вы можете использовать преимущества конкурентности, что очень распространено в веб-разработке (это та же основная «фишка» NodeJS).

### Concorrência + Paralelismo: Web + Aprendizado de Máquina { #concurrency-parallelism-web-machine-learning }

Com **FastAPI** você pode levar a vantagem da concorrência que é muito comum para desenvolvimento web (o mesmo atrativo de NodeJS).
