The Green Web Dataset API allows developers to automate real-time checks against the Green Web Dataset. It provides endpoints that allow developers to check if a single website domain is served from a green web host.
You can test it in a browser, and integrate it into your own digital services in a simple way.
We also make this data available in bulk via daily snapshots from the green domains dataset. This is a list of the last 12 months worth of domains showing as green in our checks, and is used for a number of tasks, including data analysis, privacy-focussed search engines and intergration into a range of web auditing tools. Learn more about the data on datasets.greenweb.org.
