So as I said before. @deso APY is a set of points in time and for each point there is specified reward. Locking further in time after the last point would make no extra reward. Reward is added immediately when you lock coins. Coins are just added out of nowhere.

To get list of all APY points is actually easy.... It is simple GET request with user public key

By default @focus app makes only 1 point for 1 year. But you can really make it much more interesting. I have been adding multiple points via BitClout app. In this example there are 3 points - 1 day, 2 days and 365 days.
