Covid Tracking Project vs LAPIS

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'.

LAPIS is the open, keyless REST API behind covSPECTRUM, serving aggregated counts, sequence details, and mutation queries over SARS-CoV-2 genomic data drawn from public sources like GenBank and Nextstrain, documented via an OpenAPI v2 endpoint at lapis.cov-spectrum.org. The frontend's old ETH Zurich domain, cov-spectrum.ethz.ch, now 301-redirects permanently to cov-spectrum.org — 'url' corrected to the live domain. A live GET against lapis.cov-spectrum.org/open/v2/ returns Access-Control-Allow-Origin: *, reconfirming the stored 'yes' cors.
