Answer 1

This api will return a value if account belongs to Modern billing

Answer 2

I believe you're using the wrong API. To get Billing info you must provide billing account name:

GET https://management.azure.com/providers/Microsoft.Billing/billingAccounts/{billingAccountName}?api-version=2019-10-01-preview

https://learn.microsoft.com/en-us/rest/api/billing/2019-10-01-preview/billingaccounts/get

PS: you can use the "try it" and test if it will return the information you need.

You can also query usage API and use one of the available dimensions to get cost related info:

POST https://management.azure.com/{scope}/providers/Microsoft.CostManagement/query?api-version=2019-11-01
