Covid Tracking Project
The COVID Tracking Project's public archive API, serving the US state- and national-level testing, hospitalization, and case/death time series the volunteer project compiled through early 2021. Data collection officially ended 2021-03-07 and the project shut down, but the JSON (v1/v2) and CSV endpoints continue to serve that final historical dataset unchanged since a 2021-06-01 build. A live GET against api.covidtracking.com returns Access-Control-Allow-Origin: *, correcting the stored 'no' cors to 'yes'.
