Understanding Currency Exchange Rate APIs
An API, or Application Programming Interface, acts as a bridge that allows different software applications to communicate with each other. A currency exchange rate API provides real-time or historical data on the exchange rates between different currencies. This data can be used for various purposes, such as financial reporting, forex trading, travel expense calculations, and more.
Free currency exchange rate APIs are particularly valuable for developers and small businesses that need access to exchange rate data but may not have the budget for premium services. These APIs typically offer basic features at no cost, with the option to upgrade to more advanced functionalities if needed.
