How to get transaction fee for sending some ltc to another account?

estimatesmartfee is a api call method to get transction fee for sending some ether. If my account has 1 ether, when I check with the api call it works fine, but when I have 0.999 ltc, the estimatesmartfee method does not work, rather I get JSON integer out of range (code -1). Please let me know is there any other way to find transction fee for sending any amount of ltc.
