    "description": "The Bloomberg Open API (BLPAPI) is a service-oriented, socket-based API used by the Desktop API,\nServer API (SAPI), B-PIPE, and Bloomberg Platform products. It is **not natively HTTP/REST** \u2014\nclients use the BLPAPI SDK (C, C++, Java, .NET, Python, Perl, COM Excel) over a TCP session,\ntypically against `localhost:8194` for the Desktop API or against the customer's Server API host.\n\nThis OpenAPI document is a best-effort REST-style projection of the BLPAPI service surface so\nthat the request/response and subscription paradigms can be cataloged, browsed, and tooled\nalongside other API artifacts. It is derived from the **BLPAPI Core Developer Guide v1.6\n(8/30/2016)** and the **BLPAPI Core User Guide**.\n\nThree paradigms exist in BLPAPI: Request/Response, Subscription, and Publishing. Only the\nRequest/Response paths are modeled here as HTTP operations; subscription topics are documented\nvia the `x-blpapi-subscription` extension on the relevant paths and in `tags`.\n\n\nContact Support:\n Name: Bloomberg L.P. \u2014 Enterprise / Open API",
