Would it be possible to get 'transaction history' as json data request as shown in http://forum.toribash.com/showthread.php?t=444661 (Toribash API)

I understand the security problem with login information passed trough URLs. But would there be any serious issues having the data pulled without logging in? Since data such as QI .TC amount, join date and latest match, held by a player is public anyway? (trough viewing player profile)
