Both Fiat onramping and pay with any ck supported cryptocurrency for automated topups is on our roadmap.
We don’t currently have a developer sdk for CycleOps, but we are coming out with a frontend sdk soon for ICPTopup.com - the easiest way to top up canisters with cycles. ICPTopup.com is currently only pay with ICP, but we plan to add the same multi-currency payment flows there.
