Notice: The COVID Tracking Project has ended all data collection as of March 7, 2021. The existing API will continue to work until May 2021, but will only include data up to March 7, 2021.

Our public data API provides access to all of our data at a national and state level. We provide data in both JSON and CSV format. You can also download CSV data directly.

Version 2 of our API is available.

  • Our data is provided under our project-wide data license.
  • Fields may over time be marked as deprecated. These fields may remain static or change to null values after a period of two weeks.
  • New fields may be added without warning, but will not alter the structure of the data. If you are using CSV files, make sure to use the column names from the file to lookup data, not the column numbers, which can change.
  • All URLs in our API, including state codes, should be in lower-case.
  • We do not support cross-domain requests using CORS.
