Covid-19 India vs Covid Tracking Project

A volunteer-run archive of India's COVID-19 statistics — state- and district-level confirmed/recovered/deceased counts and vaccination totals — served as JSON (v4 endpoints) and CSV from data.covid19india.org. The original api.covid19india.org project and its per-request JSON routes were deprecated in August 2021 in favor of these v4/CSV endpoints; the data itself is a static historical snapshot, last modified October 2025 per the response headers, not a live daily feed. A live GET against data.covid19india.org returns no Access-Control-Allow-Origin header, resolving the stored 'unknown' cors to 'no'.

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'.
