Here is how SPOT options work: the trader inputs a scenario (for example, "EUR/USD will break 1.3000 in 12 days"), obtains a premium (option cost) quote, and then receives a payout if the scenario takes place. Essentially, SPOT automatically converts your option to cash when your option trade is successful, giving you a payout.
