Since we signed up with Google shopping's data feed, we've had a barrage of image bot thiefs pounding our site. They aren't walking the site, they're using the Google API.. they have to be since the image sizes that we have in the feed and the location isn't accessible publicly from our website.
Just though I'd give you guys a heads up as to what appears to be going on. If your competitor has use of the API and you don't set in google merchant to not allow use of your data in the API then be prepared to defend.
