Hey,
PAS will indeed be releasing an API web service in the future. This will be a full fledged API that allows full customization of your site and extremely custom integration.
The time line for the release of this is not yet known, it's likely several months down the line at the minimum.
In the meantime we do have a barebones XML feed that will provide you with the offers, signup bonuses, and rates for each of your poker rooms that you are offering through PAS. More information on this existing feed can be found on our wiki.
