Lists API
⏰ Old Post
This post is over 7 years old - it might be slightly outdated and consigned to the history books.
We've just launched the BuiltWith Lists API! The API lets you get reports in XML/JSON format. You can also specify a whole range of parameters, one of our favourites is the "SINCE" parameter, for example you can show "show me all sites that started using Magento in the last 30 days" with a query like this -https://api.builtwith.com/lists1/api.xml?KEY=[YOUR KEY]&SINCE=30 Days Ago&TECH=MagentoEasy!
