Bulk dataset catalogue

Cost: 0 credits. Every dataset this API publishes as pre-built files, with the daily files and monthly bundles that exist right now: rows, bytes per format, digest, when each was generated, and the URL that serves it. Read it before pulling, and re-read it nightly — a day's file is regenerated for three nights after the day (late results, late closing lines) and its digest changes when its rows do.

Daily files are Business and above; monthly bundles are Platform and above. Both formats are always present: format=parquet (typed columns, snappy) and format=csv (gzip).
