For use in Windows, this Java library interfaces with the Bloomberg API. 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. As part of their Open Market Data Initiative the library is offered under a "free-use" license, which allows unrestricted access to the interface's header files, documentation, and programming examples. Extensive documentation, including code examples, is available in the Developer Documentation and at the API website.
Zinc bridges the gap between bloggers and content creators and the retailers that sell the products reviewed and covered.

Zinc integrates with various online retailers; so, readers/consumers no longer need to leave a site to order a product from a major online retailer.
