openapi: 3.1.0 info: title: Bloomberg BLPAPI Core Field Discovery VWAP API version: '1.6' summary: OpenAPI representation of the Bloomberg Open API (BLPAPI) Core services. description: 'The Bloomberg Open API (BLPAPI) is a service-oriented, socket-based API used by the Desktop API, Server API (SAPI), B-PIPE, and Bloomberg Platform products. It is **not natively HTTP/REST** — clients use the BLPAPI SDK (C, C++, Java, .NET, Python, Perl, COM Excel) over a TCP session, typically against `localhost:8194` for the Desktop API or against the customer''s Server API host. This OpenAPI document is a best-effort REST-style projection of the BLPAPI service surface so that the request/response and subscription paradigms can be cataloged, browsed, and tooled alongside other API artifacts. It is derived from the **BLPAPI Core Developer Guide v1.6 (8/30/2016)** and the **BLPAPI Core User Guide**. Three paradigms exist in BLPAPI: Request/Response, Subscription, and Publishing. Only the Request/Response paths are modeled here as HTTP operations; subscription topics are documented via the `x-blpapi-subscription` extension on the relevant paths and in `tags`.
