I’ve started working on my homepage jmoz.co.uk which I’m building in Python/Django, mainly for a learning exercise. One of the things I wanted was to get some of my content from Pinterest, unfortunately their API isn’t working or hasn’t been built (as of June 2012).
I built a small scraper which pulls me my pins and spits it out in json. I built it using Silex which is a small lightweight framework built off of the Symfony2 components.
I’ve deployed the scraper as Pinterest API, give it a go, see if it can provide you some of your Pinterest content to use on your app, make sure you cache it!
