Check if maintenance mode is active via admin Api

I am trying to check the maintenance mode via api.
From the sales-channel-API i get the Information for every Saleschannel but i only want to get the Information for Saleschannels from type Storefront.

Is it possible to check via filter if the typeId equals 8A243080F92E4C719546314B577CF82B?
Or is there a better solution?

Thanks for your help.
