Wintermute
Wintermute is a leading global algorithmic trading firm and cryptocurrency market maker providing institutional-grade liquidity across centralized exchanges, decentralized finance (DeFi) protocols, and over-the-counter (OTC) markets. Its offerings span OTC spot trading for hundreds of tokens, options with bespoke structures, forwards, CFDs, programmatic "API liquidity", and a DeFi trading and liquidity-provisioning arm, plus Wintermute Ventures, an early-stage investment vehicle. Access to Wintermute's trading services is institutional and onboarding-gated through the node.wintermute.com portal (authenticated via an Auth0-backed OIDC / OAuth2 identity provider); there is no public self-serve developer API or open OpenAPI at this time. Added to the API Evangelist network as a portfolio company of Lightspeed Venture Partners and Pantera Capital.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Wintermute the way a machine reads it — 1 machine-readable artifact, 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 — Wintermute scores 10.3/100 (minimal), with a separate agent-readiness read of 4/100 (human only). 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.

Each block below is one kind of artifact we hold for Wintermute. 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.
Security Posture 1
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.
