Fixer API is not just an exchange rate data provider. It provides a wide variety of features with smooth integration to any platform. Fixer API is powered by 15+ exchange rate data sources and delivers real-time exchange rates for 170 world currencies, and plays a significant data source role for users who need forex exchange like data.
The Fixer exchange rate API has multiple endpoints, each serving a different use case, like getting only one currency data or fetching historical data about the forex exchange rates. Moreover, you can convert from one currency to another and retrieve Time-Series data for one or multiple currencies.
Moreover, check out these tutorials that we have shown you how to integrate Fixer.io APIs into your Node.js web app or Delphi cross-platform application.

{ "success": true, "timestamp": 1519296206, "base": "EUR", "date": "2022-03-03", "rates": { "AUD": 1.566015, "CAD": 1.560132, "CHF": 1.154727, "CNY": 7.827874, "GBP": 0.882047, "JPY": 132.360679, "USD": 1.23396, [...] } } |
As you can see, in any development environment, you can easily integrate Fixer APIs. As represented above, the API’s response – when queried for real-time exchange rates – always includes a timestamp object containing a standard UNIX timestamp indicating the time the given exchange rate data was collected, a base object containing the three-letter currency code of the base currency, a date object including the date the given exchange rate data was gathered. A rates object containing the accurate exchange rate data.
