Euronext N.V. is the leading pan-European exchange operator, running regulated cash and derivatives markets in Amsterdam, Brussels, Dublin, Lisbon, Milan, Oslo, and Paris, and owning Borsa Italiana and power exchange Nord Pool. Its market data arm sells real-time, delayed, historical, index, and reference data through the low-latency Optiq Market Data Gateway (UDP multicast SBE feed, also cloud-delivered), Optiq flat files, and the Euronext Web Services JSON API, alongside the Saturn REST API for MiFID II regulatory reporting. All access is sales-gated and entitlement-managed - client specifications are published as public PDFs but base URLs and tokens are issued only at onboarding, with no self-serve developer portal.
