The oracle app id may change in the future, we will keep the same data structure for reading prices.

Just a simple subroutine for integration into ASC1:

ARC-4 Compliant Subroutine:

@Subroutine(TealType.uint64)
def get_asset_price(folks_feed_oracle: abi.Application, asa_id: abi.Asset):
    asa_info = App.globalGetEx(folks_feed_oracle.application_id(), Itob(asa_id.asset_id()))
    return Seq(asa_info, Assert(asa_info.hasValue()), ExtractUint64(asa_info.value(), Int(0)))
