Bloomberg L.P. Reference API

openapi: 3.0.3
info:
  title: OpenFIGI Filter Reference API
  description: 'The OpenFIGI API is the free, public REST API operated by Bloomberg as

    Registration Authority for the Object Management Group (OMG) Financial

    Instrument Global Identifier (FIGI) standard. It maps third-party

    identifiers (TICKER, ID_ISIN, ID_CUSIP, ID_SEDOL, ID_BB_GLOBAL, COMPOSITE_ID_BB_GLOBAL,

    etc.) to FIGIs and exposes search and filter endpoints across hundreds of

    millions of active and inactive securities.


    The /v3 API is JSON over HTTPS. Authentication is optional via the

    `X-OPENFIGI-APIKEY` header; supplying an API key raises rate limits.


    Note: /v2 is deprecated with a sunset date of July 1, 2026 — clients should

    migrate to /v3 endpoints and switch error handling from "error" to "warning"

    on no-match responses.
