About this API

The Currency Exchange API is a financial tool that provides real-time, reliable global foreign exchange rate data. It connects to authoritative financial data sources to provide developers with the latest exchange rates for over 150 global currencies. With this API, your application can easily perform currency conversions, display multi-currency prices, track exchange rate fluctuations, and analyze historical exchange rate data. Whether you are building a cross-border e-commerce platform, a financial analysis tool, or an application serving international travelers, this API can provide you with an accurate and easy-to-integrate exchange rate solution, ensuring your users always get the latest market information.

Key Features

• Real-time Exchange Rate Data: Provides near real-time foreign exchange rates, with data update frequencies ranging from every hour to every minute or even higher, ensuring the timeliness of information.
• Extensive Currency Coverage: Supports the vast majority of global legal tenders, including the US Dollar (USD), Euro (EUR), Japanese Yen (JPY), Chinese Yuan (CNY), as well as some cryptocurrencies.
• Currency Conversion Function: Provides a direct conversion endpoint. Simply enter the source currency, target currency, and amount to get an accurate conversion result.
• Historical Data Query: Allows querying of historical exchange rate data for a specific date or period, which is very valuable for financial reconciliation, market trend analysis, and academic research.
• Flexible Base Currency: Supports using different currencies as the base currency to obtain the relative exchange rates of all other currencies, meeting diverse business needs.

Use Cases

Scenario 1: Provide Multi-currency Pricing Display for a Cross-border E-commerce Website

Situation: An online store targeting the global market wants to display product prices in the local currency of its visitors based on their geographical location. Implementation: The website backend first determines the visitor's country/region and their local currency (e.g., GBP for a user from the UK) through an IP geolocation API. Then, the backend calls the Currency Exchange API to get the latest exchange rate between the store's base currency (e.g., USD) and the user's local currency (GBP). Finally, all product prices are converted and displayed to the user in British pounds in real-time. This greatly improves the shopping experience for international users and significantly increases conversion rates.

Scenario 2: Develop a Powerful Travel Budgeting and Expense Tracking App

Situation: A mobile application designed for international travelers needs to help users easily convert currencies and record expenses when consuming abroad. Implementation: The app has a built-in currency converter function. When a user spends a sum in Japanese Yen (JPY) abroad (e.g., in Japan), they can enter the amount of the expense in JPY in the app. The app will call this API to get the real-time exchange rate between the user's home currency (e.g., USD) and the Japanese Yen, and immediately display how much the expense is in USD. All records are summarized in the user's home currency, so that travelers can clearly understand their total spending and facilitate budget management.

Scenario 3: Implement Multi-currency Invoices and Reports in an Enterprise Financial Management System

Situation: A multinational company's financial software needs to process multi-currency income and expenses from different national branches and generate unified financial reports. Implementation: When the system needs to generate a quarterly financial report based on USD, it will extract all transactions recorded in non-USD currencies (such as EUR, JPY) from the database. For each transaction, the system will call the Currency Exchange API's historical data function to get the exchange rate on the day the transaction occurred. Then, it will use the historical exchange rate of that day to accurately convert the transaction amount into USD. In this way, the system can generate accurate and compliant consolidated financial statements that truly reflect the company's financial situation in different markets.

How it Works: Endpoints & Response

The core function of this API is implemented through a conversion endpoint, which receives the source currency, target currency, and amount as parameters.

The JSON object of the response has a concise and clear structure. The convert_result object directly provides the key information for the conversion: base (source currency), target (target currency), and most importantly, rate (exchange rate). Developers only need to multiply the original amount by this rate to get the conversion result. The time_update object provides the timestamp of this exchange rate data (time_unix and time_utc), which is crucial for applications that need to record the timeliness of data, ensuring data transparency and traceability.
