Urban Sky
Urban Sky is a Denver-based aerospace company, founded in 2016, that designs and operates reusable stratospheric microballoons for high-altitude remote sensing, persistent aerial surveillance, communications relay, and atmospheric data collection. Its balloons launch in under five minutes, float at 61,000-75,000 feet for multi-day missions, and carry the modular Wallabee payload platform with RGB, VNIR, and LWIR thermal sensors delivering 10cm-resolution imagery with real-time downlink. Through its Atmosys software platform, Urban Sky publishes an SDK for developers (JavaScript and Python, delivered via CDN loader) that streams real-time balloon telemetry over WebSocket and provides mission imagery access, serving defense and intelligence, commercial monitoring, and science and weather markets. Urban Sky is a Techstars portfolio company.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Urban Sky the way a machine reads it — 4 machine-readable artifacts across 1 API, 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 — Urban Sky scores 33.3/100 (thin), with a separate agent-readiness read of 28/100 (agent aware). 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 Urban Sky
Each block below is one kind of artifact we hold for Urban Sky. 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.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Real-time balloon telemetry feed delivered over WebSocket via the Urban Sky SDK (JavaScript and Python, distributed by CDN loader from sdk.atmosys.com), with balloon and unassig...
Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 2
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.
