Long-Term Stock Exchange
The Long-Term Stock Exchange (LTSE) is a U.S. Securities and Exchange Commission-registered national securities exchange headquartered in New York, built to support companies and investors committed to long-term value creation. LTSE operates a principles-based equities trading platform that accepts order entry over the MEMO FIX and MEMO SBE (Simple Binary Encoding) protocols and distributes real-time market data - depth of book, top of book, and last sale - via the MEMOIR multicast feed. Beyond the exchange it offers private-markets and cap-table software plus long-term listing standards. LTSE does not publish a public REST/OpenAPI developer API; participant connectivity (Direct, Extranet, Telco via NY4) and technical specifications are provided through its Market Operations team.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Long-Term Stock Exchange 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 — Long-Term Stock Exchange scores 18.3/100 (emerging), with a separate agent-readiness read of 0/100 (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.
