Polymarket API.
Crowd-priced mainlines for accurate models.

We pull Polymarket esports match and map markets into one normalized feed with sportsbooks and DFS. Crowd-priced mainlines give your model a probability anchor when a single book is stale or skewed: GET /v6/esports/{sport}/props?book=polymarket and consensus GET /v6/esports/{sport}/lines.

Frequently asked questions

Is there a Polymarket esports API?

Polymarket publishes market data; KashRock normalizes esports events into GET /v6/esports/{sport}/props?book=polymarket and consensus GET /v6/esports/{sport}/lines alongside Kalshi and Thunderpick.

Why include Polymarket in a props model?

Crowd-priced match/map mainlines are a clean probability prior. Combining them with sportsbook and DFS lines helps models stay accurate when one venue is stale or skewed.

Free tier?

Sandbox is $0/mo. Consensus lines across Polymarket, Kalshi, and Thunderpick are on Hobby+.
