Chariot Defense

Chariot Defense is a San Francisco-area defense technology company building high-voltage, hybrid-electric power systems for the modern battlefield. Its AMPHORA family (the 24 VDC / 5 kW A24 and the 400 VDC / 35 kW A400) and the upcoming VANGUARD platform deliver quiet, high-density, transportable power that replaces loud, fuel-hungry diesel generators, cutting energy signature and fuel use while powering distributed systems such as drones, sensors, electronic warfare, command and control, additive manufacturing, and directed-energy weapons. Founded in 2022 by Adam Warmoth, the company has raised $41M (a $34M Series A led by Andreessen Horowitz plus an $8M seed) and its systems are fielded by the U.S. Army and the Defense Innovation Unit. This is a hardware/defense company profiled in the API Evangelist network; it publishes no public developer API, portal, or documentation.

Chariot Defense is profiled on the APIs.io network. Tagged areas include Company, Defense, Defense Technology, Energy, and Power Systems.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/chariot-defense: open an issue to ask a question, or submit a pull request to add artifacts.
