Limbo Labs (limbolabs.com)
Limbo Labs was, in its own words, "a small technical team in san francisco" whose products were to "begin launching in july 2010". The company surfaced in the 500 Global portfolio listing and was added to the API Evangelist network as a lead. Enrichment found no company to enrich: limbolabs.com carried a single-page placeholder from 2010 through roughly 2015 and never grew past it — an Internet Archive enumeration of the domain returns only eleven distinct captured URLs, all of them the one landing page plus its stylesheets, jQuery and four images. No product, developer portal, API reference, OpenAPI or Swagger document, SDK or machine-readable specification was ever published or archived. By 2018 the domain served a JavaScript-wall parking page, and it now redirects to an Afternic "for sale" lander, so the brand is retired. The website URL carried on the inbound 500 Global portfolio record, readyforzero.com, is a mis-joined row: it belongs to ReadyForZero, a separate 500 Global personal-finance company, and it no longer resolves. This profile is retained as a historical, defunct-provider record with no active API surface.
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 Labs (limbolabs.com) 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 Labs (limbolabs.com) scores 6.8/100 (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.
