There are many ways to travel and experience new places, and it doesn't always have to include impersonal and expensive hotels. Imagine having your own warm, more personal space when you travel; a home away from home that cuts travel costs as well. This is the concept behind 9Flats. It's a service that connects those who have a room, apartment or house to rent with those looking for more personal, affordable, alternative accommodation. The 9Flats API makes this functionality available to third party developers who may want to integrate it with other applications.
Google releases new Gmail API to give finer grained control and greater speed, potentially exploding the number of use cases. More on the implications of Netflix closing its API. Plus: check in to your hotel room with your phone, and Android offers a new camera API.
An application that shows you if your train will be late, and that in real-time! Even better, imagine that bundled with an API that gives you access to all that data. So happened in Germany with the application Zugmonitor (German for train monitor) and the corresponding Zugmonitor API.
