About this dataset
Every day, the Site Scanning program runs a scanning engine to dynamically pull down lists of domains from various sources and then scan them with a collection of scan plugins to gather data on them.
The resulting data that populates this API then can be seen as having two main utilities:
Providing a fairly comprehensive dataset of US federal government websites.
Providing various information and analysis about each of these websites.
In addition to querying the data via API, you can also download it directly as a CSV or JSON file.
