The established service provides free, unrestricted access to raw data for customers for its financial market information. The same publish/subscribe and request/response interactions available via its proprietary interface can be accessed via API. This functionality gives access to data on current market trades, either real-time or delayed, along with reference data on reference data, historical information, and records of intraday trading.
API methods support selection by security using standard ticker symbols and the provider's own "Open Symbology" across classes of securities. Effective dates and date ranges may also be specified to retrieve historical results. Sources of pricing data are designated.
Bloomberg has launched Enterprise Access Point, a website that provides "ready-to-use" datasets which includes regulatory, pricing, and reference. The website also allows clients to use a RESTful API to programmatically retrieve complete and comprehensive data from Bloomberg's publishing platform.
Previously we looked at APIs that readers follow the most using our tracking functionality. This time we measured the APIs readers show interest in by counting the number of times a user clicks an outbound link to a provider's site. This is a metric that may better signal developer interest.
Bloomberg recently announced the launch of OpenFIGI.com and the OpenFIGI API to provide exchanges, data providers, custodians and other organizations direct access to multiple new tools for identifying, mapping and requesting the Financial Instrument Global Identifier (FIGI).
