Limbo
Limbo is a direct-to-consumer digital weight-loss and metabolic-health program operated by Vitals in View, Inc., with subsidiaries in the UK (company no. 15047668) and Ireland (company no. 725671). Members wear a body-worn "energy sensor" that reads metabolic signals, and a companion app turns those readings into personalized, nudge-based guidance intended to change eating habits without calorie counting. The company is Seedcamp-backed, raised a seed round in September 2022, and is mid-rebrand from Limbo (limborevolution.com) to Viv (viv.co), with the marketing site now served from content.viv.co. Limbo publishes no public API, developer portal, SDK, or /.well-known/ discovery surface; this profile captures its identity and probed security posture only.
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 Limbo 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 — Limbo scores 10.3/100 (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.

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