Coronavirus in the UK vs Covid Tracking Project

The UK Health Security Agency's public data API — successor to the original coronavirus.data.gov.uk service, which now 301-redirects to ukhsa-dashboard.data.gov.uk — serving case, death, hospitalisation, and vaccination figures for COVID-19 alongside other respiratory illnesses like flu and RSV, broken down by UK nation, region, and local authority. No API key is required; the dataset is organised into browsable themes, sub-themes, and topics from the root JSON endpoint, with COVID-19 confirmed live under infectious_disease/respiratory. The stored url is corrected to the current docs entry point since the old one now redirects here. A live GET against api.ukhsa-dashboard.data.gov.uk returns Access-Control-Allow-Origin: *, resolving the stored 'unknown' cors to 'yes'.

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'.
