Adcolony, once an app developer for iOS, is now focused on creating mobile HD video ads. The Adcolony APIs are two RESTful APIs, Publisher Earnings (which retrieves in CSV format) and MATA, which gives access to the CPI campaign statistics. Fields covered in the Earnings API are Date Range, Earnings, Completed Video Views, Fill Rate, Sessions, eCPM, DAU. The MATA API is based on the open standards from the Mobile App Transparency Alliance (thus the name), and uses HTTP authentication. It uses your user email and API key for verification.
