OpenFIGI — Bloomberg instrument IDs

Map between ISIN, ticker, CUSIP, SEDOL and FIGI for financial instruments.

OpenFIGI is Bloomberg's open standard for identifying and cross-referencing financial instruments. Map between ISIN, CUSIP, SEDOL, ticker and FIGI (Financial Instrument Global Identifier), plus search and filtering on instrument properties. Acts as the glue between oslo-bors (Norwegian exchange data), esma (FIRDS) and gleif (LEI). Free without a key (low rate); an optional free API key (OPENFIGI_API_KEY) gives higher limits.
