Looking to build a payments/exchange aggregator on Appgyver

Hello , I am interested in building a payments/exchange aggregator on Appgyver and I am wondering if this is a good idea. It would work through 3 different apis that already aggregate this data flow and connectivity. Can Appgyver only build static pages or can I populate pages with data from external sources? Sorry I am new to this no code space and I am trying to figure out the possibilities.

thanks,

Felix
