Bloomberg Open API announced recently - is it just the Bloomberg SDK which had been (limitedly) exposed to public for quite a while?
My understanding is tha
The API's will provide full access to LIVE data, and developers can thus provide applications and develop against the API without paying licencing fees. Consumers will pay for any data received from the apps provided by third party developers, and so BB will grow their audience and revenue in that way.
NOTE: Bloomberg is offering this programming interface (BLPAPI) under a free-use license. This license does not include nor provide access to any Bloomberg data or content.
