Alternatives to the Free Currency Converter API

As you may have noticed, the Free Currency Converter API service is no longer available on this domain. Instead, this site now aims to become a universal reference guide for developers and companies looking for free, cost-effective currency converter web services & APIs. 

In case you have not already, take a look at our Full API Comparison.

As a quick heads up on our conclusions - if you're still looking for an alternative to our former API service, you might want to sign up for the currencylayer API's Free Plan. It is entirely free, lets you make more than a thousand monthly calls and offers a wide range of features. 

You could also have a look at the Xignite API, although they do not provide a free subscription plan, they do offer a free 7-day trial for 250 API calls. 

I'd like to give you brief summaries about both of the above mentioned services below:

Focused on performance, accuracy and ease of integration, the currencylayer API offers free real-time exchange rate and currency conversion services to developers and startups around the world.

There will always be abusers of free things

I was shocked when someone reported that my service is getting slow. Upon checking, I noticed that there are devs who abused the service by send tons of requests in a short span of time. I setup a counter for my API and was more shocked to see the numbers.

How many? The top user sends more than a whopping 100,000++ requests to the server in less than one hour! This is crazy. The second highest sends around 10,000+ requests per hour. Because of this, I have to blacklist these abusers. I have updated my terms of service that the free API will have a limit of 3,000 requests in one hour which is more than fair. So far, everything is back to normal.

Guys, please be considerate of other users. Design your system well and do not abuse the free service. Thank you.
