CS2 props in JavaScript — one call, eight books

Published 2026-10-08 · by KashRock

CS2 is the deepest esports props market: map-scoped kills and headshots, priced by eight DFS books at once. Here's the whole integration.

1. Install and fetch the board

npm install kashrock

import { KashRock } from "kashrock"

const kr = new KashRock("kr_demo_swagger_public_readonly")  // read-only demo key
const { props } = await kr.props("cs2")
console.log(props[0])
// { player, stat_type, line, direction, odds, book, propId, match … }

2. Find the best line on a player

One propId per player market, shared by every book — filter on it and the over/under pair sits in the same row:

const target = props[0].propId
const offers = props.filter((p) => p.propId === target)

for (const o of offers) {
  console.log(o.book, o.direction, o.line, o.odds)
}
// prizepicks  over  19.5  -119
// underdog    over  18.5  -105   ← softer line
// betr        over  19.5  -110

3. Everything else is the same client

await kr.lines("cs2")       // consensus lines (Hobby+)
await kr.matches("cs2")     // schedule + results
await kr.liveGames("cs2")   // live map scores
await kr.researchBoard()    // graded research surface
await kr.historyTape()      // tape for backtests
