description: Exegy is a St. Louis-based provider of low-latency market data
  infrastructure, trading platforms, and predictive trading signals for capital
  markets, backed by Marlin Equity Partners after its 2021 merger with Vela
  Trading Systems and subsequent acquisitions of Enyx and NovaSparks. The firm
  sells managed FPGA ticker plants (Exegy Nexus), software feed handlers (SMDS,
  nxFeed), the Axiom normalized data feed, the Metro options trading platform,
  and market access products (nxAccess, FrontTrade, SREX). Client access to
  normalized real-time and historical market data is delivered through the
  proprietary Exegy Client API (XCAPI), a C++/C#/Java library for Linux and
  Windows, while Metro exposes the Subway socket API and Freeway algorithmic
  API - none of which are publicly documented HTTP APIs. All developer
  documentation sits behind customer logins (Exegy Customer Portal, Object
  Trading DMA portal, MarketDataPeaks), making this an entirely sales-gated,
  entitlement-managed offering with no self-serve API surface.
