Covid-19 Datenhub vs LAPIS

Robert Koch Institute's ArcGIS Hub aggregating dozens of official German COVID-19 datasets — case, death, vaccination, and hospitalisation figures by Kreis and Bundesland — each independently queryable as a standard Esri ArcGIS REST Feature Service rather than through one unified endpoint. A live query against the flagship RKI_COVID19 FeatureServer (services7.arcgis.com) returns Access-Control-Allow-Origin: *, resolving the stored 'unknown' 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.
