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. 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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Euronext the way a machine reads it — 7 machine-readable artifacts across 5 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Euronext scores 30.4/100 (thin), with a separate agent-readiness read of 17/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Euronext
Each block below is one kind of artifact we hold for Euronext. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 5
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
