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.
