We charge businesses for high volume use of our API. Our API performs on-demand conversion between 3 word addresses <> latitude/longitude which enables businesses and services across the world to build what3words into their websites, apps, and processes. We have a free tier for low volume use and special arrangements for qualifying non-profit organisations. More details on our API can be found at developer.what3words.com.
