BetOnline.ag odds API
BetOnline.ag is a sportsbook serving US bettors from offshore. PropLine pulls its odds into one REST API for 35 competitions (MLB, NBA, WNBA, NFL, NHL, NCAAB, NCAAW, NCAAF, Tennis, UFC, Boxing, CFL and 23 soccer leagues). Prices are pregame only: we stop polling a game once it starts. Filter to this book with bookmakers=betonlineag.
No credit card. 1,000 requests / day on the free tier.
What we carry from BetOnline.ag
Sports
Soccer leagues
This list is generated from the sports we poll BetOnline.ag for. A competition only returns BetOnline.ag odds while the book has a board up for it, so an off-season league comes back empty.
