I have pointed them to the API documentation that I use, however they were uninterested in that. I also tried contacting the maintainers of the API, they didn't have anything for me.

Actually I did ask them, they (unsurprisingly) didn't have anything like that.

What is someone were to trade one cryptocurrency for another?

For example, if I bought Litecoins with Bitcoins, and later sold for a gain in Bitcoins, how would I be taxed? From the article it seems I would only be taxed until I ultimately realized my gains in USD. Would I have to maintain a record of all my "altcoin" transactions in this case?

The article mentions there is a $200 exemption for personal transactions. However this only applies to personal transactions, not investments.

This also appears to not yet apply to Bitcoin, only "recognized" currencies like the Euro.
