Sports Betting API

Everything a betting product needs from one REST API — odds, player props, hit rates, expected-value and arbitrage signals, and live scores, all keyed to canonical events.

Overview

MoneyLine is a sports betting API built for developers shipping betting tools, models, and analytics. Beyond raw odds it computes the derived signals products actually need: no-vig fair pricing, positive expected value, cross-book arbitrage, and player-prop hit rates over recent windows.

Every market — game lines and player props — is normalized to American odds and grouped under a single canonical event ID, so the data lines up across sportsbooks, DFS platforms, and exchanges without any reconciliation on your side.

Key features

Odds + derived signals

Raw lines plus no-vig fair odds, +EV, arbitrage, and edge — computed for you, not left as an exercise.

Player props with hit rates

L5 / L10 / L25 / season hit rates joined to active props for in-window events.

One canonical event model

Sportsbooks, DFS, and exchanges all map to the same eventId.

Live scores

Scores and status alongside the odds you already pull.

FAQ

What can I build with it?

Odds comparison, bet tracking, +EV and arbitrage scanners, prop research tools, and AI betting assistants — anything that needs normalized odds and derived signals.

Do you include DFS and exchanges?
