Get one kind of betting edge (arbitrage, +EV, middle) on Sportsbook API API
Edges of one type across every game: ARBITRAGE (and _LIVE), MIDDLE (and _LIVE), PLUS_EV_AVERAGE or BYB_V1, each with its market, game and the legs (book, odds, line); +EV items carry the market's fair implied probability. No value field: compute it from the legs. 1 request (666 +EV edges, 1 MB, 2026-10-22).
1 live route on Web / SEO, from $0.00 per call. Every route below answered our last live test on 2026-11-02; the gateway re-tests them daily.
