Looking Glass

Looking Glass Factory builds light field (holographic) displays — group-viewable 3D screens ranging from the pocket-sized Looking Glass Go to 16", 27", 32" and 65" panels — plus the software that drives them. For developers, the core surface is Looking Glass Bridge: a local runtime that exposes an HTTP REST API on http://localhost:33334/ for enumerating connected displays, opening the media player, building playlists of Quilt and RGBD holograms, and controlling playback. Around it Looking Glass ships official client libraries — the typesafe bridge.js (@lookingglass/bridge), a WebXR polyfill (@lookingglass/webxr) that targets the displays from any WebXR framework, a Python Bridge SDK, the legacy HoloPlay Core C/C++/C# SDK, and engine plugins for Unity, Unreal and Blender. Looking Glass Blocks (blocks.glass) hosts holograms on the internet. The company is backed by Uncork Capital and headquartered in Brooklyn, New York.

Looking Glass publishes 6 API contracts indexed on the APIs.io network, including Autostart API, Devices API, Orchestration API, and 3 more. Tagged areas include Company, Holographic Displays, Light Field, 3D, and Developer Tools.

The Looking Glass catalog on APIs.io includes 1 Spectral governance ruleset.

Looking Glass’ developer surface includes documentation, API reference, engineering blog, pricing, signup flow, authentication, and 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

10 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 36.1 — up to +16.0 composite points
Operational Transparency scores 13.2 — up to +11.3 composite points
Access Clarity scores 44.7 — up to +11.1 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/looking-glass/apis.yml: open an issue on github.com/api-evangelist/looking-glass to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
XR & Graphics (XR, 3D, GPU graphics)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
