Fetch Series

Fetch the recurring series (fourth tier above Event -> Market -> Outcome) that this venue exposes. Returns an empty array on venues without a series concept (Limitless, Smarkets, Probable, Metaculus, Baozi, Hyperliquid, SuiBets, Polymarket US). - params.id -> a single matching series with its events populated where supported. - no params -> the full list, typically without nested events for payload size.
