Bloomberg Opens Its Data Distribution Technology

January 31, 2012

New York — Bloomberg is opening its market data interfaces for
use by technology professionals globally, without cost or
restriction, the company announced today. Bloomberg’s
application programming interface, known as BLPAPI, is used
daily by more than 100,000 professionals across the financial
services industry and is now publicly available under a free-use
license at*

BLPAPI powers global market data distribution to desktops,
workgroups and enterprise applications. In addition to Bloomberg
Professional service subscribers, non-Bloomberg customers,
vendors and software developers can now use BLPAPI as an
alternative to proprietary technologies for market data
distribution. This is Bloomberg’s latest move in support of its
Open Market Data Initiative – an ongoing effort to embrace and
promote open solutions for the financial services industry.

“Today’s global financial marketplace depends on the free flow
of timely and accurate market information,” said Thomas Secunda,
Founding Partner and Global Head of Bloomberg’s Financial
Products and Services division. “By embracing open technologies
for market data distribution, we remove layers of expense, erase
restrictive license agreements and enable innovation.”

“We intend to evolve BLPAPI into an open standard with the help
of an independent committee charged with managing the future
development and stability of a truly open market data
interface,” said Shawn Edwards, Chief Technology Officer of
Bloomberg LP. “Open technologies allow our customers, partners,
and others to direct resources towards developing innovative
services instead of coping with rigid technologies.”

Bloomberg’s open API follows the release of Bloomberg’s Open
(BSYM), a system to identify securities across all
global asset classes. BSYM is an alternative to proprietary
security identifiers that has been adopted by leading global
securities exchanges and financial services organizations.

BLPAPI works with a comprehensive set of programming languages
and operating systems, including Java, C, C++, .NET, COM and
Perl. Other benefits of using the open API include:

-A comprehensive technical definition of a market data interface
that includes publish/subscribe, request/response, all built on
a flexible service-oriented design

-An MIT-style license that allows users to copy and use BLPAPI
interfaces with any market data service, applications or adapter

-A simple and intuitive interface technology that is suitable
for high volume and low latency applications

* Bloomberg is offering its programming interface (BLPAPI) under
a free-use agreement. This does not apply to any content.
