Skip building a pricing engine. Get no-vig fair odds, positive expected value, cross-book arbitrage, and edge signals computed server-side from normalized odds.
The MoneyLine betting analytics API turns raw odds into the signals betting products actually surface: no-vig fair pricing, positive expected value (+EV), and cross-book arbitrage. These are computed for you from the normalized, multi-book odds feed.
Arbitrage excludes DFS operators (their prices are indicative, not tradeable) and limits exchange participation to an allowlist with a sportsbook-only consensus sanity check, so you get fewer false signals. DFS still counts toward value and EV.
Per-outcome fairOdds derived from cross-book implied probabilities, normalized.
Positive expected-value flags against consensus fair pricing.
Cross-book arbs with DFS excluded and exchanges allowlisted and sanity-checked.
Arbitrage, value, and EV edges from one endpoint.

}Surface positive expected-value bets ranked by edge across books.
Find risk-free cross-book opportunities with false signals filtered out.
Use no-vig fair odds as a market baseline for model evaluation.
Implied probabilities from all books are averaged, normalized so the binary pair sums to 1.0, then converted back to American odds (no-vig).
DFS prices are indicative, not tradeable lines, so including them produces false arbitrage signals. DFS is still included in value and EV.
Exchange participation is limited to an allowlist (e.g. ProphetX, Novig) and every exchange offer is checked against a sportsbook-only consensus first.
