Lithos

Lithos Carbon is a deep-tech carbon-removal company that spreads crushed basalt on croplands to accelerate enhanced rock weathering, converting atmospheric CO2 into dissolved bicarbonate that is permanently stored as ocean carbonates. The company pairs soil models and machine learning with agronomic partnerships to maximize durable carbon dioxide removal while improving soil health and crop productivity for farmers, and sells the resulting high-permanence carbon credits to corporate buyers. Surfaced as a Greylock portfolio company and added to the API Evangelist network; an enrichment pass confirmed the company publishes no public API, SDK, or developer surface as of this profile.

Lithos is profiled on the APIs.io network. Tagged areas include Company, Deep Tech, Carbon Removal, Climate, and Enhanced Rock Weathering.

Lithos’ developer surface includes engineering blog, support, signup flow, and 2 more developer resources.

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