Use this endpoint as the authoritative per-ticker stored-date check before requesting raw Kalshi data. It does not prove every date between start_date and end_date is present, and it does not prove every payload field is complete. Kalshi has a known parser issue from 2026-03-31 through 2026-04-24 and a known storage ingestion gap from 2026-05-04 through 2026-05-11; see Data Quality.
