The simple answer is - Yes; However, there are conditions.
This service is intended for everyone and so we don't want any selfish individuals treating it as their own personal data feed and soaking up the bandwidth for their own purposes. Show a little courtesy and common sense and the feeds can be kept running at a reasonable cost to ourselves. For example, if you have a website or smartphone application that requires the feeds then please don't sent all of your users directly to this site. Instead, download the data to your own server and get the users to retrieve the data from your own site.
We reserve the right to block any users that we consider to be exhibiting unreasonable use.
You should also note that we cannot guarantee the accuracy of the exchange rates or the format of the rss feeds and so if you are using them for a business that relies on them for your day-to-day operations then you should really consider switching to a more reliable (i.e. paid-for) service. In short, you use this data at your own risk and if you lose money as a result of using these feeds then it's your own fault.
Oh, and one other thing... please provide a courtesy link to this website from within a prominent page on your own website/application to ensure that we get credited with providing a valuable service for the benefit of the search engine algorithms of this world. This will enable us to keep the service free of charge for everyone.
That's it... any further enquiries then feel free to contact us
