i need to pull ltc_btc nmc_btc and so on. For parsing I use XsuperObject

xs:=so(тут функция получения данных с сервера(она работает все нормально))
 for I := 0 to xs.O['pairs'].Count-1 do
   begin
     StringGrid1.RowCount:=StringGrid1.RowCount+1;
     StringGrid1.Cells[0,i]:=xs.????????????????????????????????????
 end;

I would be very grateful for help.
