In the world of finance and e-commerce, the ability to perform accurate currency conversions is crucial. Developers often face the challenge of choosing the right API to facilitate these conversions. In this blog post, we will compare two prominent APIs: the Currency Calculation API and the Currency Rate API. We will explore their features, use cases, performance, and scalability, ultimately providing a recommendation on which API to choose based on specific needs.
Overview of Both APIs
Currency Calculation API
The Currency Calculation API is designed to facilitate seamless real-time currency conversion calculations. It ensures accuracy and adaptability for applications that require swift and precise exchange rate computations. This API serves as a gateway to the global financial realm, enabling effortless currency conversions by leveraging updated exchange rate data. Users can initiate conversions by sending requests that specify the amount, source currency, and target currency, receiving the converted amount based on the latest exchange rate.
Currency Rate API
The Currency Rate API enables developers to retrieve real-time exchange rates between different currencies. This API simplifies the process of currency conversion by allowing developers to integrate it into their applications, enabling users to convert currency values seamlessly. The API connects to a data source that provides real-time exchange rates, ensuring that developers can automatically retrieve the latest rates without manual updates.
Side-by-Side Feature Comparison
Currency Calculation API Features
The Currency Calculation API offers several key features:
Currencies Conversion
This feature allows users to convert between two specified currencies. To use this feature, developers must indicate two currencies along with an amount in the parameters. The API then returns the converted amount based on the latest exchange rate.
{"success":true,"validationMessage":[],"result":{"from":"USD","to":"EUR","amountToConvert":10,"convertedAmount":9.52199581}}In this response, the fields include:
- success: Indicates whether the conversion was successful.
- validationMessage: Contains any validation messages if applicable.
- result: An object containing the conversion details.
- from: The source currency.
- to: The target currency.
- amountToConvert: The original amount specified for conversion.
- convertedAmount: The resulting amount after conversion.
Supported Currencies
This feature provides a list of all available currencies. Developers can simply run this endpoint to retrieve the supported currencies.
[{"symbol":"USD","name":"United States Dollar"},{"symbol":"EUR","name":"Euro"},{"symbol":"GBP","name":"British Pound"}]The response includes:
- symbol: The currency symbol.
- name: The full name of the currency.

{"success":true,"from":"USD","to":"EUR","rates":[{"pairName":"USD/EUR","price":0.908,"dayChanged":0.0027,"dayChangedByPercent":0.29,"dayChangedStatus":"+","from":"USD","to":"EUR","lastUpdated":"2023-04-27T13:12:11.116Z"}]}The response fields include:
- success: Indicates whether the request was successful.
- from: The source currency.
- to: The target currency.
- rates: An array containing the exchange rate details.
- pairName: The currency pair being converted.
- price: The current exchange rate.
- dayChanged: The change in the rate for the day.
- dayChangedByPercent: The percentage change for the day.
- dayChangedStatus: Indicates whether the rate has increased or decreased.
- lastUpdated: The timestamp of the last update.
Get All Units
This feature returns all available currency units. Developers can run this endpoint to get a comprehensive list of supported currencies.
{"success":true,"symbols":[{"country":"United States","isoCode":"USD","name":"United States Dollar","symbol":"$"},{"country":"Euro Member Countries","isoCode":"EUR","name":"Euro","symbol":""}]}The response includes:
- success: Indicates whether the request was successful.
- symbols: An array of currency objects.

- name: The full name of the currency.
- symbol: The currency symbol.
Get Real Time Converter
This feature allows developers to convert a specified amount between two currencies in real-time. Developers must insert two currency units and an amount in the parameters.
{"success":true,"from":"USD","to":"EUR","amount":100,"converts":[{"pairName":"USD/EUR","price":0.9084,"dayChanged":0.003,"dayChangedByPercent":0.33,"dayChangedStatus":"+","from":"USD","to":"EUR","lastUpdated":"2023-04-27T13:17:30.999Z","amount":100,"result":90.84}]}The response fields include:
- success: Indicates whether the conversion was successful.
- from: The source currency.
- to: The target currency.
- amount: The original amount specified for conversion.
- converts: An array containing conversion details.
- pairName: The currency pair being converted.
- price: The current exchange rate.
- dayChanged: The change in the rate for the day.
- dayChangedByPercent: The percentage change for the day.
- dayChangedStatus: Indicates whether the rate has increased or decreased.
- lastUpdated: The timestamp of the last update.
- result: The converted amount.
