Momentus
Momentus is a U.S.-based commercial space company providing in-space transportation and infrastructure services. Founded in 2017 and headquartered in San Jose, California, the publicly traded company (NASDAQ: MNTS) designs, manufactures, and operates Orbital Service Vehicles such as its Vigoride platform, using water plasma propulsion technology to move satellites and payloads between orbits, host payloads, and deliver last-mile satellite deployment. Momentus serves private satellite operators, government agencies, and research institutions. As of this profile it publishes no public developer API, developer portal, SDK, or technical integration surface; it was surfaced as a Y Combinator (S18) portfolio company and added to the API Evangelist network as a company profile.
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.
Momentus is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — Momentus scores 7.2/100 (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.

The organization behind the API
Momentus is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
