Build a Player Props Tracker with Live Odds

Player props are the fastest-growing betting market. This guide builds a tracker that fetches player-level markets (points, rebounds, assists, goals, cards, shots) from the FieldFunded API and displays them with live odds updates.

What Are Player Props?

Player props are bets on individual player performance rather than match outcomes. Examples:

Sport	Example Props	Market name
Basketball (NBA)	LeBron James Over 25.5 Points	Player Points O/U
Soccer	Haaland Anytime Goalscorer	Anytime Goalscorer
American Football	Mahomes Over 2.5 Passing TDs	Player Passing TDs O/U
Tennis	Djokovic Over 9.5 Aces	Player Aces O/U
Ice Hockey	McDavid Over 0.5 Goals	Player Goals O/U

What You’ll Use

SDK Method	Endpoint	Purpose
`getEventOdds()`	`GET /v1/events/{id}/odds`	Get all markets including player props
`getEvents()`	`GET /v1/events`	List events with prop markets
`search()`	`GET /v1/events/search`	Find specific player matchups
`checkBet()`	`POST /v1/bets/check`	Settle player prop bets

Step 1: Find Player Prop Markets

Player props are returned alongside standard markets in the odds response. Filter by market name patterns:

import { FieldFundedSDK } from '@fieldfunded/sdk';

const ff = new FieldFundedSDK({
  apiKey: process.env.FIELDFUNDED_API_KEY!,
  baseUrl: 'https://api.fieldfunded.com/v1',
});

const odds = await ff.getEventOdds(eventId);

// Filter for player prop markets
const playerProps = odds.markets?.filter((m: any) => {
  const name = m.name.toLowerCase();
  return (
    name.includes('player') ||
    name.includes('goalscorer') ||
    name.includes('assists') ||
    name.includes('rebounds') ||
    name.includes('points') ||
    name.includes('cards') ||
    name.includes('shots')
  );
}) || [];

console.log(`${playerProps.length} player prop markets found`);
for (const prop of playerProps) {
  console.log(`\n${prop.name}:`);
  for (const sel of prop.selections.slice(0, 5)) {
    console.log(`  ${sel.name}: ${sel.odds}`);
  }
}

Step 2: Build a Player Dashboard

Group props by player name for a clean display:

interface PlayerLine {
  player: string;
  market: string;
  line: string;
  odds: number;
  market_id: string;
  selection_id: string;
}

function extractPlayerLines(markets: any[]): PlayerLine[] {
  const lines: PlayerLine[] = [];

  for (const market of markets) {
    for (const sel of market.selections) {
      lines.push({
        player: sel.name.split(' - ')[0] || sel.name,
        market: market.name,
        line: sel.name,
        odds: sel.odds,
        market_id: market.id,
        selection_id: sel.id,
      });
    }
  }

  return lines;
}

const lines = extractPlayerLines(playerProps);

// Group by player
const byPlayer = new Map<string, PlayerLine[]>();
for (const line of lines) {
  const existing = byPlayer.get(line.player) || [];
  existing.push(line);
  byPlayer.set(line.player, existing);
}

for (const [player, props] of byPlayer) {
  console.log(`\n${player}:`);
  for (const prop of props) {
    console.log(`  ${prop.market} — ${prop.line}: ${prop.odds}`);
  }
}

Step 3: Track Odds Movements

Poll at intervals to detect line movements — useful for finding value:

const previousOdds = new Map<string, number>();

async function checkMovements(eventId: string) {
  const odds = await ff.getEventOdds(eventId);
  const props = odds.markets?.filter((m: any) =>
    m.name.toLowerCase().includes('player')
  ) || [];

  for (const market of props) {
    for (const sel of market.selections) {
      const key = `${market.id}_${sel.id}`;
      const prev = previousOdds.get(key);

      if (prev && prev !== sel.odds) {
        const direction = sel.odds > prev ? 'DRIFTED' : 'SHORTENED';
        console.log(
          `${direction}: ${sel.name} in ${market.name}: ${prev} → ${sel.odds}`
        );
      }

      previousOdds.set(key, sel.odds);
    }
  }
}

Step 4: Settle Player Prop Bets

Player props settle automatically through the same settlement API as standard markets. Complex props (goalscorer, assists) may take 10-30 minutes after the match ends:

const result = await ff.checkBet({
  event_id: eventId,
  market: 'Anytime Goalscorer',
  selection: 'Erling Haaland',
  stake: 25,
  odds: 1.65,
  market_id: propMarketId,
  selection_id: propSelectionId,
});

console.log(`Result: ${result.status}`);
console.log(`Payout: $${result.payout}`);

Scenario	Requests/day	Monthly	Plan
Check props for 5 events daily	5	150	Free
