Question 1

What does FxRatesAPI do?

Accepted Answer

FxRatesAPI is a foreign exchange rate data provider offering real-time, historical, and time-series exchange rate data for over 180 currencies through a clean REST API. The service aggregates rates from multiple financial data sources and delivers accurate exchange rates for currency conversion, price display, accounting, and financial analytics applications. For Nigerian developers and businesses building applications that deal with multiple currencies — which describes the majority of Nigerian fintech, e-commerce, and accounting software — FxRatesAPI provides reliable NGN currency data alongside all major global currencies.

Nigeria's position as Africa's largest economy means that currency exchange rates are not just a technical feature — they are a core business concern. The USD/NGN exchange rate directly affects the cost of imported goods displayed on Nigerian e-commerce platforms, the naira value of remittances sent from Nigerians in the diaspora, the financial reporting of Nigerian companies with foreign currency revenues, and the investment decisions of Nigerians holding foreign currency assets. An accurate, current USD/NGN rate, updated at least daily, is a fundamental requirement for dozens of categories of Nigerian applications.

The /latest endpoint returns current exchange rates for all 180+ supported currencies from a specified base currency. To get the current USD/NGN rate, a Nigerian application calls the endpoint with base=USD and receives the NGN rate in the response. The same call returns rates for EUR, GBP, JPY, and every other supported currency simultaneously — making it straightforward to build multi-currency displays that show prices in multiple currencies at once.

The /convert endpoint handles currency conversion arithmetic — pass the amount, the source currency, and the target currency, and FxRatesAPI returns the converted amount at the current rate. For Nigerian e-commerce platforms that need to convert a product price from USD to NGN for display, this eliminates client-side conversion code and ensures the rate used is always current.

Historical exchange rate data is available via the /historical endpoint, returning rates for any past date. This is critical for Nigerian accounting and ERP applications that need to record transactions at the exchange rate on the transaction date — a requirement for Nigerian financial reporting that must comply with both IFRS standards and FIRS (Federal Inland Revenue Service) guidelines on foreign currency transactions.

The /timeseries endpoint returns exchange rate data over a range of dates with daily resolution, enabling trend analysis and charting. For Nigerian currency analytics tools, this data powers time-series charts showing the USD/NGN rate history — valuable context for Nigerians trying to understand naira depreciation trends and optimize their currency holding decisions.

Fluctuation data via the /fluctuation endpoint shows the change in exchange rates over a specified period — useful for Nigerian fintech apps that want to display "the naira weakened 2.3% against the dollar this week" type of contextual information alongside current rates.

The free plan provides 1,500 requests per month with daily rate resolution — sufficient for low-traffic applications where real-time rates are not critical. For applications needing hourly or minute-level rate updates (forex comparison tools, live price displays on high-traffic Nigerian e-commerce sites), the Basic plan at $9.99/month provides up to 100,000 requests and hourly resolution. The Professional plan at $29.99/month provides minute-level resolution and up to 1 million requests per month — appropriate for Nigerian fintech applications with significant user traffic.

All endpoints accept a simple api_key query parameter with no request signing required, making FxRatesAPI one of the quickest currency data integrations available for Nigerian developers. Responses are JSON by default with XML available as an alternative format.
