Lumius
Lumius is a Y Combinator (Spring 2026) medical-imaging startup building fast, smart, accessible real-time 3D ultrasound systems — described as "a 3D camera for the body." The technology aims to move ultrasound beyond traditional 2D imaging to intelligent, AI-assisted 3D visualization across larger volumes, with an initial focus on vascular access and central-line placement (where roughly half of first attempts fail among new clinicians) and future targets including blood-clot detection, tumor diagnosis, and biopsy guidance. The company partners with academic institutions such as Duke University and Columbia University. Lumius is a hardware/device company with no public API, SDK, or developer platform; its products are pre-market and not intended for medical use. This profile was added to the API Evangelist network as a VC portfolio lead and has been reviewed by the enrichment pipeline.
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.
Lumius is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — Lumius scores 5.7/100 (minimal), with a separate agent-readiness read of 0/100 (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.

The organization behind the API
Lumius is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
