Currency Conversion

The Reliable Currency Exchange API offers a conversion feature that allows users to convert between two specified currencies. To use this feature, developers must indicate the two currencies in the parameter without spaces (e.g., 'EURGBP'). This feature is essential for applications that require real-time currency conversion.

{"rates":{"EURGBP":{"rate":0.855258,"timestamp":1692197584}},"code":200}

The response includes the conversion rate and a timestamp, which can be used to display the most recent conversion data. This is particularly useful for financial applications that need to provide users with up-to-date information.
