Verify our track record yourself.
Every bet we've publicly claimed is cross-checked against MLB StatsAPI (the same official league API used by MLB.com and every sportsbook) and ESPN's core data API. Click any bet below to see the official source. If our record doesn't match, we lose. That's the deal.
Outcome verification
Every MLB bet stores the league's official game_pk (game primary key). We fetch the box score from statsapi.mlb.com/api/v1/game/{game_pk}/boxscore and re-derive the result — team runs, player strikeouts, first-inning totals — from official league data. WNBA bets are verified against ESPN's core API.
Closing line verification
Every 15 minutes we snapshot the odds market for all 12 US sportsbooks and store the raw values. When we publish a closing line, we check it against those independently-captured snapshots. Bets tagged SNAPSHOT VERIFIED have the closing price corroborated by at least one recorded snapshot for that exact player, market, book, and line.
Profit math
For every bet: profit = stake × (decimal_odds − 1) if won, −stake if lost, 0 if void. No rounding tricks. Every profit number can be manually re-derived from the American price and stake — try it. Bankroll math is idempotent: current_bankroll = starting_bankroll + SUM(profit).
What we found & fixed
An internal audit on Aug 6, 2026 discovered our closing-line-capture script was matching prices to the wrong player when the bet row lacked a canonical player_id. We fixed the matcher, rebuilt 28 corrupted closing lines from actual snapshot data, and added source tracking to every bet. Details are in the methodology page.
