Build a Live Esports Odds App with Real-Time Market Data

Get live odds for CS2, League of Legends, Dota 2, Valorant, and 4 more esports titles — all from a single API. This guide shows you how to build a real-time esports odds dashboard with map-level markets, live scores, and automatic settlement.

Why Esports API Data Is Hard to Find

Most sports data APIs treat esports as an afterthought — limited coverage, delayed odds, and zero settlement support. FieldFunded covers 8 esports titles with the same depth as traditional sports: 1,000+ markets per event, sub-second latency, and full automatic settlement including map winner, total maps, handicap, and player-specific props.

What You’ll Use

Step 1: Fetch Live Esports Events

Filter by sport key to get only esports events:

Step 2: Get Deep Market Odds

Esports events support the same market depth as traditional sports. A typical CS2 match includes Match Winner, Map Winner (per map), Map Handicap, Total Maps Over/Under, and more:

Step 3: Live Scores with Map Tracking

Esports scores include per-map breakdowns:

Step 4: Settle Esports Bets Automatically

Settlement works identically for esports and traditional sports — markets resolve within seconds after a match ends:

Rate Limit Math

On the free tier (10,000 req/month, 2 req/s):
  • Polling live esports events every 30s = 2,880 req/day (1 sport)
  • Polling 3 esports titles every 60s = 4,320 req/day
  • On-demand odds checks = ~1-2 req per user action
For a dashboard tracking CS2 + LoL + Valorant with 60s polling: ~4,300 req/day = ~130,000 req/monthStarter plan ($29/mo) covers this comfortably.

Architecture for Production

Cache odds for 5-10 seconds to reduce API calls. Live scores can be cached for 15-30 seconds since round scores don’t change sub-second.
