Esports Data API.
CS2, LoL, Dota props, lines & stats.
One affordable esports data API: normalized props, lines, matches, and player stats. Instant key. No enterprise quote.
What the esports data API covers
Props and lines
Live ingested player props across CS2, LoL, Dota 2, and Valorant. One schema, many books.
Matches and stats
Schedules, box scores, game logs, and map-level stats — not just who won.
Stable IDs
Players, teams, matches, and props keep the same ID when a book spells the name differently.

Frequently asked questions
What does an esports data API include?
KashRock covers event schedules, player props and lines, match data, player stats, and outcome verification across CS2, LoL, Dota 2, and Valorant.
Is there a free esports API tier?
Yes. Sandbox is $0/mo with an instant key — CS2 player props so you can verify the schema. Paid plans start at $29/mo.
Where do I get DFS books like PrizePicks and Underdog?
Use the DFS Esports API page and GET /v6/esports/{sport}/props. That route is the PrizePicks / Underdog / LoL DFS board.
Do you pull prediction markets for modeling?
Yes. Kalshi and Polymarket esports mainlines (plus Thunderpick sportsbook prices) land on the same schema and power GET /v6/esports/{sport}/lines consensus — useful priors so models are not stuck on one venue.
