Not sure but i Don't think it can be done as your need to get it from paypal if there was as we can not link in to your account to to get the data from paypal.
For a meter like that, you can find codes on how to make it online. Just google for it. Most of those are done with Javascript coding or C++ or even JQuery from what I have seen. They can be coded with Javascript, some HTML and styled with CSS.
Hope this shines a bit more light on what you are looking for.
I still say it can not be done without paypal's server data and there is no chance in getting that info from them. paypal do not have a system that gives you that sort of thing as far as i know.
