Each venue publishes its own API: Novig at docs.novig.com, Kalshi at docs.kalshi.com, Polymarket at docs.polymarket.com. On 15 Nov 2026 The Odds API listed all three in its us_ex region, and TheRundown listed Kalshi and Polymarket on paid plans. novigapi.com covers Novig only, in depth. (Source: [The Odds API: bookmaker list](https://the-odds-api.com/sports-odds-data/bookmaker-apis.html))

If you want one price per venue in one call, a multi-book feed is simplest. If you want each venue's book and trades, you will end up reading each one's own API, because no feed checked here carries full depth for all three.

## Where novigapi.com falls short

> novigapi.com has no Kalshi or Polymarket data at all. Use their own APIs or a multi-book feed for those venues.
