# dxFeed

> dxFeed is a market data distributor (a Devexperts subsidiary, Munich HQ) delivering real-time, delayed, historical, and on-demand financial market data across equities, ETFs, futures, options, indices, FX, fixed income, and crypto — 3.5M instruments, ~200,000 simultaneous streaming clients — plus reference data (Instrument Profile Format), Morningstar-sourced fundamentals, options analytics, and news. The developer surface is openly documented but production access is sales-gated: credentials (endpoint URLs, login, password) and per-service entitlements arrive via onboarding. Public no-credential demo endpoints serve delayed data.
