Inertia

Inertia is a commercial fusion energy company pursuing laser-driven inertial confinement fusion to deliver safe, affordable, grid-scale clean power. Building on the December 2022 ignition milestone at the National Ignition Facility (NIF) in Livermore, Inertia is developing a modular laser system composed of roughly a thousand smaller, more efficient lasers, mass-manufacturing 4.5mm fusion fuel targets for under a dollar each, and firing them ten times per second to power a 1.5 gigawatt baseload, dispatchable power plant. The company is a deep-tech venture tracked in the API Evangelist network as a portfolio-lead stub; it operates a corporate/marketing web presence and publishes no public developer or API surface at this time.

Inertia is profiled on the APIs.io network. Tagged areas include Company, Deep Tech, Fusion Energy, Clean Energy, and Inertial Confinement Fusion.

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/inertia: open an issue to ask a question, or submit a pull request to add artifacts.
