What I'm looking for is a way to break this captcha: https://www.nfe.fazenda.gov.br/PORTAL/FormularioDePesquisa.aspx?tipoConsulta=completa

Notice that the image alternates based on 2 types of images. Anyone knows a OCR (optical character recognition) 'damm good'for this? Other solutions also accepted (except proxing).

I'm not looking for spamming, I just want to automatize my Software instead of proxing the image for the user.

Nowhere in the site says it is forbidden to automatically parse the image.
