VRChat is a social virtual-reality platform where users create avatars and worlds in Unity with the first-party VRChat SDK (Worlds, Avatars, Udon and UdonSharp), publish them through the VRChat Package Manager, and meet inside a persistent multi-user universe playable on PC VR, standalone headsets and desktop. VRChat operates a live web API at api.vrchat.cloud that powers its own client and website, but it explicitly does not document, version, or support that API for public use: its Creator Guidelines state endpoints may be added, removed, or changed with no warning. The machine-readable surface VRChat does publish is the creator toolchain — the VPM package listings at packages.vrchat.com, the vpm CLI on NuGet, the OSC and OSCQuery interfaces for external avatar and input control, an llms.txt documentation index, and a public Statuspage.
VRChat publishes 2 APIs on the APIs.io network. Tagged areas include Company, Virtual Reality, Social Networks, Gaming, and Metaverse.
VRChat’s developer surface includes documentation, getting-started guide, engineering blog, support, signup flow, changelog, CLI, and 20 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/vrchat: open an issue to ask a question, or submit a pull request to add artifacts.

description: The HTTP API at api.vrchat.cloud/api/1 that backs the VRChat client and the vrchat.com website — authentication,
users, friends, worlds, avatars, instances, groups, files and notifications. VRChat operates this API publicly but explicitly
does not document it, publish a machine-readable specification for it, or support third-party use of it. The only first-party
guidance is the API section of the Creator Guidelines, which sets User-Agent, rate-limit and credential-handling rules
for anyone who calls it anyway. The unauthenticated /api/1/config endpoint returns 200 with JSON and is the surface probed
for this profile.

detail: VRChat operates a live public web API at api.vrchat.cloud (the anonymous /api/1/config endpoint returns 200 JSON)
but states in its own Creator Guidelines that it does not document that API for public usage and that endpoints may be
added, removed, or relocated with no warning — so no OpenAPI, no auth reference, and no error catalog exist to harvest,
and the widely circulated vrchatapi/* specs are community reverse-engineering that this profile deliberately does not
attribute to VRChat.
