The Tripit C# Sample Code by Tripit demonstrates how to access the API with the aim to implement travel organization features into mobile applications and web services. It includes consumer Key, consumer Secret, token, and token secret.
Even though Alaska Airlines was one of the first airlines to offer an iPhone application, allowing travelers to check-in and use their phone as mobile boarding pass, early efforts were essentially just "screen-scraped" from the companies website, providing a very poor user experience, not really delivering on the process of the mobile web. Since you're a ProgrammableWeb reader, you can probably guess what the company needed. After all, mobile has fueled API growth.
Today OnStar, a GM company focused on in-car communication and security, announced what it calls an API. Though not yet released, nor totally open and perhaps not even an API, the move is certainly part of "car as a platform." Building apps for cars is a movement that hasn't seen much progress since Ford's announcement two years ago. Though there is still a lot of potential, especially with the car culture in much of the US, some have questioned whether safety will stifle in-car apps.
Getting from A to B in the most cost effective way can be difficult if you're just guessing as you go. TaxiMe is an application that provides users with cost estimates for cab fares and trip information for major cities in the U.S. and Canada. This means users can plan their journeys beforehand and know exactly what the costs involved will amount to. TaxiMe's API allows access to cab contacts and rates for these different cities.
