Convert one currency to another that returns result in json format.
Quick API Sample (JSON and JSONP support):
Examples now use version 7 of the API. Added currency symbols to currencies and countries, minor fixes.
Free Currency Converter API started in year 2014, it's now 2021 and we're up ever since. It offers free web services for developers to convert one currency to another. You are free to use this for personal or commercial application however it offers no warranty (See license below for more information).
Currency values are updated every 60 minutes. If you need a realtime web service or a service that updates more frequently, you may checkout the premium service at CurrencyConverterAPI.com.
If you're using the free exchange rate API in production, I highly advise you to have a fallback. One possible fallback are the premium and prepaid servers, as they are completely separate from the free servers and won't get affected with interruptions from the free servers. Or better yet, make the premium your main one and the free API as the fallback.
Convert queries accepts a maximum of 2 conversion parameters to avoid abuse of the service and to help maintain the health of the web services. Free API keys are also limited to one IP address. If you need more than the limit or if you need a large amount of requests, you may contact me for more information or check the faster and production-ready server at CurrencyConverterAPI.com.
If you appreciate this site, please consider supporting by registering to the premium service. Check the pricing for more information.

Please, please, please do not abuse the free currency exchange API as many other people are using it (see terms and conditions of using the free service). Be considerate or you will be blacklisted from the free service. Please consider the premium service at currencyconverterapi.com if you need many requests in an hour. The limit for this service is 100 per hour.
Do you use this service? Tell me about it and I might feature it here!
I don't know how to license web services, so below is the closest terms I could think of. In short, this service is free even for commercial use. Using the services here will cost you nothing, $0; it is free as in beer! If you appreciate this, you could buy me a coffee.
