Climacell
Climacell (styled ClimaCell) was a Boston-based weather-intelligence startup that pioneered a "Weather of Things" approach — deriving hyperlocal precipitation and atmospheric conditions from wireless-signal attenuation, connected devices, and its own proprietary numerical weather model — and exposed it through a developer-facing REST weather API. Backed by Canaan Partners among others, the company rebranded to Tomorrow.io in 2020 and its legacy climacell.co domain now 301-redirects to www.tomorrow.io. The surviving product is the Tomorrow.io v4 Weather API, which supersedes the original ClimaCell v3 API and exposes 60+ hyperlocal data layers (core weather, air quality, pollen, fire, flood, lightning, maritime, aviation, road) with realtime, forecast, historical, map-tile, and webhook-alert access. This profile is the historical ClimaCell identity; the enriched, live provider record lives in the api-evangelist tomorrow-io repository.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Climacell 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 — Climacell scores 24.6/100 (emerging), 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 Climacell
Each block below is one kind of artifact we hold for Climacell. 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.
