The common name you propose, really throws me for a loop. Normally "monkey pod" refers to Araucaria, a southern hemisphere conifer native to places like New Zealand, Norfolk Island or Tierra del Fuego. The photo looks nothing like Araucaria. Ah, my mistake, Araucaria araucana is called the "Monkey Puzzle Tree" not Monkey Pod. See, common names are confusing. But I had time to browse Wikipedia a little.
Do you mean; Samanea saman?, or Enterolobium cyclocarpum?,or Moanalua?,or maybe Piliostigma thonningii?, or any of a dozen more called monkey pod?
Samanea saman might be your tree. Your tree seems to have compound leaves, which are a match for Samanea. In which case it is a species used for Bonsai by Philippine, and Indonesian Bonsai artists. Most images I've seen of Samanea the trees have been large, over a meter tall and very full, wide foliage canopies. Not saying you can't use them for smaller styles, this is just my recollection.
