Amentum
Amentum Holdings, Inc. (NYSE: AMTM) is a global advanced engineering and technology solutions company serving U.S. federal customers across defense, intelligence, energy, space, and civilian missions, with allied work in the United Kingdom and Australia. The company was created from the spin-off of AECOM's Management Services business in 2020, and on September 27, 2024 completed a Reverse Morris Trust transaction with Jacobs Solutions to merge Jacobs' Critical Mission Solutions (CMS) and Cyber & Intelligence (C&I) businesses into Amentum. Post-merger Amentum reports approximately $14.4 billion in fiscal year 2025 revenue, a $47.1 billion backlog, ~53,000 employees in 80 countries, and is headquartered in Chantilly, Virginia. The business is organized around six capability areas — Mission Modernization & Sustainment, Space Systems, Digital Transformation, Sustainability & Environment, Advanced Energy Solutions, and Data Analytics & Cyber. Most delivery occurs under contract through classified, CAC-gated, or program portals; no public developer portal, OpenAPI, or REST API has been identified.
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 Amentum the way a machine reads it — 7 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 — Amentum 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.
