Hidden Level

Hidden Level is a U.S.-based defense and aerospace technology company that turns radio-frequency (RF) activity into trusted airspace intelligence. Its passive RF sensing platform detects and tracks unmanned aerial systems (drones) and other activity across air, ground, sea, and space domains without requiring emitters or heavy on-site infrastructure. Hidden Level packages this as hardware sensor platforms, software platforms, and data platforms serving defense and military, critical infrastructure protection, homeland security, and public safety customers. The company hosts its platform on AWS with least-privilege access, MFA, and TLS 1.3 API communications, aligns corporate controls to NIST SP 800-171, and emphasizes U.S. design and manufacturing. Backed by Costanoa Ventures. This API Evangelist profile tracks Hidden Level's public web and security surface; the company does not currently publish a public developer portal, API reference, or SDKs.

human 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.

Kin Score

API Evangelist profiles Hidden Level the way a machine reads it — 2 machine-readable artifacts, 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 — Hidden Level scores 13.3/100 (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 Hidden Level

Each block below is one kind of artifact we hold for Hidden Level. 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 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.
