LAPIS
Query aggregated SARS-CoV-2 genomic sequence data
LAPIS (from CoV-Spectrum/GenSpectrum) serves aggregated statistics over open SARS-CoV-2 sequences — filter by mutation, lineage, date, or location and get counts back. This open instance needs no key and returns JSON, handy for genomic-epidemiology dashboards.

/sampleSample — documented GET route.
/sample/1Sample details by ID (example: 1).
/sample?limit=10Sample — documented GET route.
/sample/search?q=testSearch by query parameters.
/sample/unalignedNucleotideSequencesReturns a string of unaligned nucleotide sequences. Only sequences matching the specified sequence filters are considere
We probe a documented GET and expect 2xx JSON — full uptime and health score. Export includes every documented route below.
Stable. No schema drift observed since monitoring began — the response shape has not changed under our checks.
LAPIS: common questions
Is LAPIS free to use?
Yes — LAPIS is a free health & food API. Free tier: Free — no key (open instance). Whether the free tier allows commercial use is unclear — check the provider docs.
Does LAPIS need an API key?
No — LAPIS needs no API key or signup. You can call it straight away; rate limits still apply (Unpublished).
Can I call LAPIS from the browser?
Yes — LAPIS returns CORS headers over HTTPS, so front-end code can fetch it directly with no backend proxy. Use the fetch snippet on this page, or hit "Run live" to try it now.
Is LAPIS up right now?
As of our last scheduled check, LAPIS is unmonitored. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
