The Bloomberg API provides free, unrestricted access to raw financial data on current market trades (either real-time or delayed), reference data on historical information, and records of intraday trading. This library, for use with Windows OS, allows users to interface with the API from within Java. As part of their Open Market Data Initiative both the API and library are offered under a "free-use" license, which allows unrestricted access to the interface's header files, along with documentation and programming examples. Extensive documentation, including code examples, is available in the Developer Documentation and at the API website.
Location data and storage company SimpleGeo has announced plans to change its pay-per-use pricing for the SimpleGeo API, removing a free option for low volume users. Instead, the company will offer tiered pricing, with 60 day free trials at every tier.
