AltspaceVR
AltspaceVR was a social virtual reality platform founded in 2013 where people gathered in shared 3D spaces for live events, meetups, classes, comedy shows and conferences. Google Ventures (GV) was an early investor. Microsoft acquired the company in 2017 and folded it into its Mixed Reality division, then announced in January 2023 that the platform would close, shutting it down permanently on 2023-03-10 in favor of Microsoft Mesh. AltspaceVR published no hosted HTTP API; its developer surface was the Mixed Reality Extension (MRE) SDK for building server-hosted 3D world extensions in Node.js, plus the earlier web-based AltspaceSDK. Every SDK repository is now archived and altvr.com redirects to microsoft.com. This profile is retained as a historical record of a terminated platform, not as a live integration target.
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 AltspaceVR 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 — AltspaceVR scores 11.5/100 (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.

How we profile AltspaceVR
Each block below is one kind of artifact we hold for AltspaceVR. 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.
