Before we get to the SDK and API topics, check out this list of RPC providers which you can review and setup your dedicated JSON-RPC endpoints ahead of time, to be used by your app. The endpoints are either free-to-use or have a generous allowance*, where developers can focus on developing apps, rather than setting up a blockchain infrastructure.
