Long story longer. I've added currency formatting into some of my stuff (Handel / AxKit::XSP::Currency) and I want to add currency conversion as well. I know there are a few modules on CPAN for this.

First we have Finance::Currency::Convert that uses Finance::Quote. This seems to rely on many difference sources for conversion rates. Not bad, but a little bulky.

Next we have Finance::Currency::Convert::XE which has restrictions by XE.com on the usages/commercial/business/personal, etc.

After that we have Finance::Currency::Convert::Yahoo which relies on scraping Yahoo Finance. That's a little fragile.

So, this leads me to this service on WebserviceX.NET. It looks nice and predictable (SOAP/RPX/GET (RESTish)), free, no restrictions that I can find. There isn't a module on CPAN for this particular converter.

So now I have a few choices. First, I can write yet another currency converter and put it up on CPAN. Next, I could just hack in some quick GET/RegExp code do do this in my app.

If it were you, what would you do?

Update: Of course, the new modules should probably be named Finance::Currency::Convert::WebserviceX, just like it's Yahoo/XE counterparts. For that matter, it could mimic both ::Yahoo and ::XE API to be a drop in replacement. :-)
