Tidal Metals

Tidal Metals is a deep-tech materials company that extracts decarbonized magnesium directly from seawater and desalination brine using only electricity from renewable sources, without mining, chemical additives, or brine waste. The company's patented process concentrates and extracts magnesium salt to address a critical supply-chain vulnerability: the United States currently produces no primary magnesium while China controls roughly 91% of global supply. Founded by Ph.D. physicists and engineers with backgrounds in nuclear engineering and plasma physics from MIT, Princeton, and Wisconsin-Madison, and backed by DCVC, Tidal Metals aims for carbon-neutral, domestically scalable magnesium production. Surfaced as a portfolio company of DCVC and added to the API Evangelist network; the company publishes no public API, developer portal, or machine-readable surface at this time.

Tidal Metals is profiled on the APIs.io network. Tagged areas include Company, Magnesium, Critical Minerals, Materials, and Cleantech.

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.

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