About these files

Pre-built bulk exports of the Serotype Database. Files are generated whenever a new HATS version is imported and served directly from object storage — no API calls, no rate limits, no per-row overhead. Each file is also produced in CSV and TSV so you can load it in your tool of choice without conversion.

Bulk API queries are capped at 5,000 rows; use these files for anything larger.

Files end in .gz — gzip-compressed for fast downloads. Decompress with gunzip file.json.gz, or load directly: pandas.read_json("file.json.gz") / read.csv(gzfile("file.csv.gz")) / gunzip -c file.json.gz | jq.
