Programmatically make Amazon purchase?

Is anyone aware of an Amazon API that allows you to purchase items programmatically?

I looked at tons of their web services (Product Advertising, MWS, etc.), and none of them seemed to do this.

I found this thread that seemed to suggest there was no solution, but there was no definitive answer: https://forums.aws.amazon.com/thread.jspa?threadID=45127

Just to be clear, I want to make a purchase with MY payment details, not on behalf of any user. I figured if ANYONE supported this, it would be Amazon. But I realize there may be business (security?) reasons not to support this as well...

http://www.zinc.io/ shows that it is, in fact, possible to do this.

I've read around the net that you could do this by sending crafted _GET responses, although I, myself, am currently trying to figure out which ones to send.

UPDATE 2019/12/10 Even though my answer was accepted as the best answer it's outdated. Please see this answer: https://stackoverflow.com/a/17180929/799155

It's not possible – I guess for a bunch of security reasons. Read through the thread you posted in your question ;)
