OpenFIGI

OpenFIGI is your entry point to multiple tools for identifying, mapping and requesting a free Financial Instrument Global Identifier (FIGI). OpenFIGI is an open system for identifying instruments globally across all asset classes. Combining the FIGI with additional descriptive meta-data, firms are able to link fragmented proprietary symbologies, fill the gaps that remain to create a data lineage, streamline the trade workflow and reduce operational risk.

OpenFIGI publishes 3 APIs on the APIs.io network: Filter API, Mapping API, and Search API. Tagged areas include Financial and Instruments.

OpenFIGI’s developer surface includes authentication, product news, signup flow, FAQ, engineering blog, and 6 more developer resources.
