Welcome to the Cooler API

Enabling you to footprint carbon emissions through a set of simple APIs.

The Cooler API enables you to calculate the carbon emissions (the carbon footprint) of products and services included within transactions using the simple Footprint endpoint, and to retrieve them using the Transactions endpoints. These APIs are the same we depend on for the Cooler Certified web application, which helps small businesses measure and neutralize* their carbon emissions.

*In the near future, you will be able to neutralize those emissions through the neutralization endpoints, as reflected in the Cooler app. Learn more at https://www.cooler.dev

What is Cooler?

Cooler is a climate-change software company that provides automated tools for measuring and neutralizing carbon footprints in service of our mission to reduce the negative impact of business operations on global warming. We measure carbon footprints by analyzing transactions with our deeply researched, science-based carbon calculator, which uses a hybrid EEIO-LCA approach, and neutralize by purchasing carbon emissions permits from cap-and-trade markets on your behalf.

Ultimately, we’re working to help you measure and neutralize as much CO2 emissions as possible to significantly reduce carbon production and decrease the greenhouse gases emitted into our air and atmosphere through commerce.
