I found it... here in the new API documentation:

addpool|URL,USR,PASS[,NAME,DESC,ALGO] (*)
               none         There is no reply section just the STATUS section
                              stating the results of attempting to add pool N
                              The Msg includes the pool URL
                              Use '\\' to get a '\' and '\,' to include a comma
                              inside URL, USR or PASS
               Name, description and algorithm are optional

So please start adding the algorithm to the addpool api command.. this is also the key to my previous request...
