BitGo.com gives you the options of 'high priority', 'medium priority', 'low priority' and 'very low priority' for setting miners fee when sending bitcoin with their web wallet.
I am using their API to send bitcoins to different addresses. How do I calculate the miners fee (corresponding to any of the various priorities) to pass to the API when sending bitcoins.
Simply put, if I want to send 0.01BTC to an address with medium priority, how do I calculate the miners fee for medium priority (and the others) with their API or any other API.
