title: Bloomberg EMSX Fills API
description: The Execution Management System API allows developers to manage and automate trading for equities, futures, and options using an event-driven model with both subscription and request-response paradigms. EMSX provides order and route management, broker integration, and fill tracking via the BLPAPI protocol. This spec models the request-response operations as REST-like endpoints.
