SideQuest is a VR content-discovery platform and independent app store for Meta Quest, PCVR, Pico, Magic Leap and WebXR headsets — the home of sideload-only, early-access and indie VR apps and games, plus tools to help users get more from their VR headset. SideQuest operates a public REST API (api.sidequestvr.com) for browsing the app catalog and reading user profiles and achievements, secured with OAuth 2.0 bearer tokens and a device-style short-code login. Backed by GV.

SideQuest publishes 5 APIs on the APIs.io network, including Apps API, Developers API, OAuth2 API, and 2 more. Tagged areas include Company, Consumer, Virtual Reality, VR, and XR.

SideQuest’s developer surface includes authentication, documentation, and 15 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/sidequest: open an issue to ask a question, or submit a pull request to add artifacts.
