Klout allows you to track the impact of your opinions, links and recommendations across your social graph, including Twitter, Facebook, Google Plus and other networks. Klout collects data about the content you create, how people interact with that content and the size and composition of your network. From there, it analyzes the data to find indicators of influence and then provide you with innovative tools to interact with and interpret the data.
The Klout API can be searched by identity and returns a score between 1 and 100 that represents Klout's calculation of that user's influence.
When defining your API strategy, a crucial decisions to make is what API business model will be used. A business model is a way to understand all of the system components that come together to allow you to create a project and add value. It helps you answer how you will make money from your API.
In preparation for next February's DeveloperWeek, organizers have launched an awards program to identify best-in-category developer tools, including best API Infrastructure and Best API Service. Award nominations are still open for API providers and toolmakers who want to see their product included in the vote, and all ProgrammableWeb readers are encouraged to share their opinions in the crowdsourced voting system. ProgrammableWeb spoke with DeveloperWeek organizer Geoff Domoracki about the launch of the awards program.
