Use the Skydeck API to access your mobile phone call log, address book, and the minutes remaining for the month. Users give permission to developers to access their call logs, address book, or minutes remaining so that their information is available for developer applications. Use of OAuth is required for all applications that use this API, although only an API key is necessary to access your own account's information.
Skydeck announced their new APIs, with the objective of enabling developers to create applications that integrate personal cell phone data into their daily online experience, including email and calendars, Facebook, MySpace, and Salesforce. "Very few developers have ever had the chance to work with cell phone data, so we're excited to see what people come up with."
