Is a hub like Nest essential for using the Google Home API?

I've built a Kotlin sample app, but I'm asking because device control is not possible without a Nest. If this is the case, even if I create an app using the Google Home API, would it be useless if my app users don't have a hub like Nest?

No, a Nest hub isn't essential for using the Google Home API. It depends on what type of integration you're building:

For cloud-to-cloud integrations, users don't need a hub - your app can directly communicate with compatible smart devices through Google's infrastructure using the Smart Home API.
For Matter-compatible devices, the Google Home app itself can serve as the controller without requiring a separate Nest hub.
If you're specifically wanting to control Nest-branded devices (thermostats, cameras, etc.), then users would need those specific devices, but not necessarily a Nest hub.
