And the rest will be handled by **FastAPI**.

If you run it and go to <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> you will see the response from Flask:

```txt
Hello, World from Flask!
```

And if you go to <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> you will see the response from FastAPI:

```JSON
{

        val jsonText = URI("https://services.gradle.org/versions/nightly").toURL().readText()
        println(jsonText)
        val versionInfo = Gson().fromJson(jsonText, VersionBuildTimeInfo::class.java)
        ReleasedVersion(versionInfo.version, versionInfo.buildTime)
    }
}
