Some Frequently Asked Questions:


How often do your rates update?

Short answer: Depending on your subscription plan, either hourly or every 10 minutes.
Long answer: Every 10 minutes we check for updates from our various sources. If updated information exists, our rates will change accordingly. Some of our sources issue updates in real time, while others issue updates every 6 hours, or once day. Less traded currencies (like the Panamanian Balboa for example) can sometimes reflect new data only a few times per day. However, most currencies will be updated every 10 minutes.


Where do you get your rates from and how accurate are they?

Our exchange rates are classed as indicative rates and are accurate enough to display price estimations. However, they will differ slightly to the final rate a user may be charged when making payment, mostly due to the buy/sell profit spread applied by the relevant payment processor and the exchange they use. We do not supply buy/sell spread data and so our rates are unsuitable for forex trading. Our sources are mainly central banks, such as European Central Bank and Canadian Central Bank. We have many sources and are always adding more so that our service is as reliable as possible.


How will I know if I am running out (or have run out) of API queries?

When you have reached 50% of your monthly currency conversion request quota you will receive an email so that you can monitor your usage. We send another email at when you have reached 90% of your monthly requests. Once you have reached your monthly request limit - after a period of "soft capping" and further notifications - the API will start to return "-4" instead of a legitimate exchange rate, indicating you have exceeded your monthly quota.


Can I get historical exchange rates from this API?

We do not currently offer any historical rates, but it is something we are working on.


What geo-location database do you use?

Our product uses IP2Location LITE data available from http://lite.ip2location.com.
