### Verifique a documentação automática da API

Agora, execute `uvicorn` com a aplicação principal, se o seu arquivo for `main.py`, seria:

<div class="termy">

```console
$ uvicorn main:app --reload

    val request =
      Request.Builder()
        .url("https://prod.idrix.eu/secure/")
        .build()

    client.newCall(request).execute().use { response ->
      if (!response.isSuccessful) throw IOException("Unexpected code $response")

      println(response.body.string())
    }
  }
