OpenFIGI API is a channel that links the financial transaction identifiers of third-party providers to the Financial Instrument Global Identifier (FIGI). FIGI aids open data identification of the trading transactions involving financial instruments that represent different classes of assets. Provided by Bloomberg on behalf of the Object Management Group, the FIGI features fixed identifiers that facilitate operational efficiencies to the spectrum of stakeholders that constitute the financial markets value chain. The OpenFIGI API conveys HTTP requests and returns responses in JSON format. It exists as a fully-supported release that comes with publicly accessible documentation.
