If you can map the dice to an outcome, that would be a useful feature. For example, in battletech if you have a 20-missile launcher, you roll 2d6 to determine how many of the 20 missiles hit -- this requires a table-lookup which slows down gaming.
This is an interesting concept. Would the API help fill in this type of feature? You could roll using the API and use the return to perform a lookup in a table you design.
