Humanitarian Data Exchange vs LAPIS

HDX is OCHA's CKAN-based catalog of over 18,000 humanitarian and public-health datasets (disease outbreaks, health-facility locations, population and displacement data) covering 250+ locations, searchable and downloadable through the standard keyless CKAN Action API (package_list, package_show, datastore_search). A live GET against data.humdata.org/api/3/action/status_show succeeds with no key, and a live Origin-header probe returns Access-Control-Allow-Origin: *, resolving the stored 'unknown' 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.
