# GET ERC20 Order Fee

This API returns 2 minimum amounts, one is based on users fee rate, the other is based on the maximum fee bips which is 0.6%. In other words, if a user wants to keep the fee rate, the minimum order is higher, otherwise, the user needs to pay more but can place lower order amounts.
