Try the Kalshi Series API

Lists Kalshi series, up to `limit` rows (default 25, max 200). Each series has its ticker, title, category, frequency, fee type and multiplier, settlement sources, and contract and contract-terms URLs. The catalogue comes back in one page, so `cursor` has no effect on this endpoint.

Response behavior

- The series catalogue is returned unpaginated, so `limit` is applied to the returned rows and `cursor` has no effect on this endpoint. - `data.cursor` is therefore empty here. Use `/kalshi/events` or `/kalshi/markets` when you need cursor-based pagination. - The catalogue is cached and shared across all `limit` values, so `data.fetched_at` is when the catalogue itself was last retrieved from Kalshi — up to 6 hours before your request, not the time of the request. Series are contract definitions and change on the order of days.
