Euronext

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.

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.
