Venues
The API covers four prediction market venues. Pass a venue's value in the venue filter on any route to narrow the results to that venue.
| Venue | Value | Region | Names traders |
|---|---|---|---|
| Kalshi | kalshi | US | Yes |
| Polymarket | polymarket | Global | Yes |
| Polymarket US | polymarket_us | US | No |
| Gemini | gemini | US | No |
Venues that name their traders
Kalshi and Polymarket publish who made each trade. Their trades include a trader with a ref and a record, and you can look those traders up with Get Trader or copy them with a trader bot.
Polymarket US and Gemini publish trades without names. Their trades return trader: null, but they still appear in trades, moves, markets, backtests and signal bots.
Polymarket and Polymarket US are separate
Polymarket (polymarket) and Polymarket US (polymarket_us) are separate venues with their own markets, prices and order books. The same question on each one is a different market with its own ref.
