The answer depends on which client you are using to call the method (JS, Motoko, Rust, dfx etc).

Maybe this should provide the answer for you:

> Personally, I don’t think that reading the cycle’s balance of a canister is too much information. However, maybe it would be best to leave that up to the community as a whole? Additionally, how can we move this forward? It would be great to get this in-front of a wider portion of the community to get an answer to if we can just make ‘canister\_status’ a public method, or if adding a separate method that only returns the list of controllers is the better route.
