Key Features of the Currency Conversion API

1. Get Conversion

The Get Conversion feature allows you to convert an amount from one currency to another. To use this endpoint, you must specify the source currency, target currency, and the amount to convert. An optional parameter allows you to retrieve historical data based on a specific date.

"from": {
"currency": "EUR",
"amount": 100
},
"to": {
"currency": "USD",
"amount": 110.50

This feature is valuable for e-commerce platforms that need to display prices in different currencies, allowing customers to see real-time conversion rates.
