Coronavirus in the UK vs Longevity World Cup

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'.

Longevity World Cup runs a public, no-auth JSON API behind its biological-age competition site, serving athlete biomarker and leaderboard data alongside biological-age calculators (phenotypic age, Bortz age) and reference data such as divisions and flags, documented via a live OpenAPI 3.0 spec at /swagger.
