4Paradigm
4Paradigm (Beijing Fourth Paradigm Intelligent Technology, HKEX 6682) is a Chinese enterprise AI company building decision-making and generative AI platforms — the Sage AIOS AI operating system, Sage HyperCycle ML/CV/OCR, SageGPT and the SageOne AI computing appliances — for banking, insurance, securities, retail, energy, healthcare and manufacturing. Its public, machine-readable API surface is published almost entirely through its open-source community at github.com/4paradigm: OpenMLDB, an Apache-2.0 machine-learning feature database with a documented REST APIServer, Protobuf/brpc cluster services and Java/Python/Go/C++ SDKs; OpenAIOS-Platform (Pineapple), a Kubernetes-based AI development platform that ships OpenAPI 3.0.3 contracts; and PhanthyMotus, an MCP-native embodied-AI agent framework whose hardware drivers are Model Context Protocol servers.
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 4Paradigm the way a machine reads it — 11 machine-readable artifacts across 4 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 — 4Paradigm scores 37.0/100 (thin), with a separate agent-readiness read of 27/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile 4Paradigm
Each block below is one kind of artifact we hold for 4Paradigm. 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 6
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.
OpenMLDB APIServer REST API
The HTTP/JSON surface of OpenMLDB's optional APIServer module — insert rows into a table, invoke a deployed real-time feature-computation service, run online/offline SQL, read d...
OpenMLDB Cluster RPC Services

PhanthyMotus is 4Paradigm's open-source embodied-AI agent framework. Every hardware driver bundle is a Model Context Protocol server exposing typed cards — sensor, actuator, pro...
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.

MCP SERVERPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSSecurity 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.

This is an independent, third-party profile of 4Paradigm, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
