First Request API Key
Responce from Pinterester:
The API was not really opened for public consumption. We pushed the docs live in an attempt to get feedback but we had to shut it down since we saw activity. We will write back the people who signed up for the beta list when we are ready.
Just hookup your phone to the computer and sniff traffic coming from your Pinterest app in Charles or Fiddler and you will see you API or access token.
