Futu

Futu Holdings Limited (NASDAQ: FUTU), operator of the Futubull and moomoo platforms, is a digital brokerage and wealth-management technology company. Its Futu OpenAPI gives developers programmatic access to real-time and historical market data and to trading across Hong Kong, US, China A-share, Singapore, Malaysia and Japan markets, plus options, futures, cryptocurrency and event (prediction) contracts. Rather than an HTTP/REST API, Futu exposes a proprietary Protocol Buffers (proto2) protocol over TCP through a locally run OpenD gateway, with official Python, Java, C#, C++ and JavaScript SDKs and an official MCP-compatible Agent Skill hub. Backed by Hongshan and Ribbit Capital.

agent aware

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.

Kin Score

API Evangelist profiles Futu the way a machine reads it — 3 machine-readable artifacts across 1 API, 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 — Futu scores 20.0/100 (emerging), with a separate agent-readiness read of 25/100 (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 Futu

Each block below is one kind of artifact we hold for Futu. 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 1

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.

Individual APIs this provider publishes, each with its own machine-readable definition.

Futu OpenAPI

Programmatic trading and market-data API for global markets, options, futures, crypto and event contracts. Proprietary Protocol Buffers protocol spoken over TCP to a locally run...

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

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.
