Markets

List Markets

List active markets grouped by event across supported venues (Kalshi and Polymarket). Filters: category, venue, subcategory (validated against the selected category), frequency (daily/weekly/monthly/hourly), date_filter (time bucket), and search. Pagination is cursor-based at the event level. The response includes available_subcategories and available_frequencies so clients can drive filter chips from the same result set.

Query parameters

Filter by category. Pass all to disable the default category filter.

venue'kalshi' | 'polymarket'

Source venue for a market.

Filter by venue. Omit to include all venues.

subcategory'nba' | 'ncaa' | 'nfl' | 'nhl' | 'mlb' | 'ufc' | 'lol' | 'epl' | 'efl' | 'la_liga' | 'world_cup' | 'bundesliga' | 'liga_portugal' | 'ligue_1' | 'f1' | 'ipl' | 'btc' | 'eth' | 'sol' | 'stocks' | 'indices' | 'etfs' | 'earnings' | 'rates' | 'inflation' | 'commodities' | 'fx' | 'jobs' | 'ai' | 'companies' | 'other'

Subcategory wire format (lowercase snake_case). Valid values depend on the selected category and are enforced server-side.

Filter events by subcategory. Valid values depend on the selected category (requires category to also be set).

frequency'daily' | 'weekly' | 'monthly' | 'hourly'

Filter events by the cadence of the underlying series. other is intentionally rejected — it's a residual response bucket, not a filter target.

date_filter'1h' | '1h-1d' | '1d-7d' | 'today' | 'this_week' | 'this_month' | 'all'

Time bucket filter. If omitted, a default 7-day horizon is applied. Pass all to retrieve all active markets regardless of close date.

cursorstring

Opaque pagination cursor from a previous response's meta.cursor. Do not construct manually.
