Explore Markets
Browse whale-active titled markets with category, platform, status, and keyword filters. Explore is Polymarket-only: the platform parameter is accepted for backward-compatibility but every request returns Polymarket markets. Paginates visible discovery entries rather than raw market rows, returns live category/platform facets alongside grouped event clusters or standalone markets, and includes total on the first page only. Categories come straight from provider metadata (Polymarket Gamma) and facets are flat value/label/count rows.
q for the full feed, or pass it to narrow by keyword.
Grouped events (e.g. “Next US president by candidate”) return one row per event with a primary market injected, so you always have something to link to.
Common filters:
q=bitcoin: keyword search against market titles.category=crypto: restrict to a category.platform=polymarketorplatform=kalshi: restrict to one platform.status=active: exclude resolved markets.sort=volume: sort by recent volume.

Query Parameters
Filter by market category (case-insensitive). A canonical bucket name (e.g. Basketball) matches every provider member that folds into it (NBA, WNBA, NCAAB); a raw provider value also resolves to its bucket. Facet values are returned as the canonical bucket.
Filter by market status.
active, closed, all Filter by source platform. Explore is Polymarket-only; polymarket is the only supported value and the parameter is accepted for backward-compatibility but does not change the result set.
