Hello 👋
You can use the Upcoming invoice API for that instead

but that checks switching to a new price, right?
what I want is to see how the price will change when I add a price to my current subscription
How can I do it?

I believe you can only add one-time prices as the invoice item

Are trying to convert the single product subscription to multi product subscription?
