Data API
Version 2 of our data API is built to solve several problems with ensuring the accuracy of data, and putting that data into context. It adds several new features:
- Data is now delivered in JSON objects that contain data and metadata
- Every endpoint includes field definitions and titles for all data
- Every field includes common equations like percentage of population, or percent increase over 7 days, where appropriate.
- Additional “simplified” endpoints to lower file-size
