ZeroMark
ZeroMark is a defense-technology company building an AI-powered targeting system for counter-drone (counter-UAS) defense. Its bolt-on hardware and software components attach to existing weapons, platforms, and sensing systems to detect, track, and neutralize small drone threats in milliseconds while minimizing collateral damage. The product line spans Apex (AI aim-assist for shoulder-mounted rifles), Vanguard (a precision system for turret-mounted and vehicle platforms effective against Group 1-3 drones), and Nexus (a command-and-control software layer that integrates deployments into shared targeting and battlespace-awareness environments). ZeroMark was surfaced as a portfolio company of a16z and added to the API Evangelist network. As of this enrichment pass the company publishes no public API, SDK, developer documentation, or open-source presence; its Nexus C2 integration is delivered through defense procurement rather than a public developer program.
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 ZeroMark 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 — ZeroMark 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.

How we profile ZeroMark
Each block below is one kind of artifact we hold for ZeroMark. 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.
