EnduroSat
EnduroSat is a Sofia, Bulgaria-based satellite manufacturer and space service provider working to make space universally accessible by lowering the cost and complexity of accessing space data. The company builds CubeSat and SmallSat platforms (FRAME Max, FRAME L, FRAME S buses and 8U/12U/16U CubeSats), avionics and communication modules (X-Band SDR, S-Band and UHF transceivers, EPS power modules, solar panels, and antennas), and delivers end-to-end Space Service, SpaceOps, and SpaceDev offerings that take customers from idea to orbit in roughly six months. EnduroSat has deployed 100+ satellites with 3,500+ modules in operation, downlinked 500+ TB of data, and serves ~450 customers including NASA, ESA, and IBM Space. It maintains an open-source GitHub organization publishing Cubesat Space Protocol (CSP) implementations and NextGen ground-station and onboard API frameworks. Backed by Founders Fund and GV.
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 EnduroSat 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 — EnduroSat scores 13.0/100 (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 EnduroSat
Each block below is one kind of artifact we hold for EnduroSat. 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.
