I am wanting to buy and sell L$ using the LibOpenMetaverse library. LibOpenMetaverse is a C# library that allows you to create programmed avatars for Second Life.
I've looked around at the docs for LibOpenMetaverse and haven't been able to find anything like what I want to do. I'm hoping to be able to buy and sell Lindens, as well as see the current L$ exchange rate.
If there is another way that someone knows of to see the L$ exchange rate, that would also be helpful.
You could scrape http://moneyslex.com/exchange_rates.php or possibly the liden site itself. I think this would require authentication though.
