Today the Guardian reported that Tesco has launched a beta API for its online shopping service. This may seem rather unremarkable given how many other websites already have fully funtional APIs. However, apparently this is the first ever API offered by a supermarket.
What this means in practice is that all sorts of applications andwidgets can be written to order groceries from tesco.com. You could be reading a recipe book on your kindle and click on a link so that all the ingredients you need are ordered from the online store. If integrated with a smart fridge and smart cupboards (via RFID tags), your account might even automatically know not to order milk because your fridge knows that you already have enough.
So here we see the first step in creating a hybrid virtual/physical kitchen, and for better or worse an idea that will surely speed up the development of the Internet of Things.
