California Catalysts develops advanced materials and stack components for electrolyzers, offering non‑iridium catalysts that lower the levelized cost of hydrogen. Founded to commercialize DOE‑funded research, the company leverages AI‑driven high‑throughput catalyst discovery to accelerate electrolysis technology. It partners with leading manufacturers and provides testing‑as‑a‑service, aiming to make green hydrogen more affordable and scalable.
California Catalysts is listed with 1 API on the APIs.io network. Tagged areas include Electrolyzers, Hydrogen Production, Catalysts, Materials, and Stack Components.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) 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/.
