21Vianet
21Vianet (VNET Group, Inc.) is the largest carrier-neutral internet and data center services provider in China, operating more than 50 data centers across over 20 cities with tens of thousands of cabinets and multi-terabit network port capacity. The company delivers hosting, managed hosting, interconnectivity, cloud, and hybrid IT infrastructure services to enterprise customers, and is the exclusive operator of Microsoft Azure, Microsoft 365, Dynamics 365, and Power Platform in mainland China through its Blue Cloud subsidiary. 21Vianet trades on Nasdaq under the ticker VNET. This profile was added to the API Evangelist network as a portfolio lead; 21Vianet does not publish a public first-party developer API program, so most API artifacts are legitimately not applicable.
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 21Vianet 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 — 21Vianet scores 6.8/100 (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.
