I did google a lot and found several providers but they either are ridiculously expensive (on the 1 000€ plus per month) or their update frequency is very slow or they don't have odds from bookmakers I am interested in.
What I look for is an odds api/feed with:
- Pre match odds updated every 5min or less. Live odds is a plus but must be updated more frequently
- Support for Betfair, Matchbook and Pinnacle - more sharper books are welcome
- At least support for the main European bookmakers. For example (at least some of the following) Bet365, WilliamHill, bwin, Dafabet, Marathon, Unibet, BetVictor, Tipico, Interwetten, Betway, Betstars, Skybet, ComeOn, MrGreen, TonyBet, xtip, cashpoint, 10bet, 888sport, bethard, bet-at-home, etc...
- At least with Football odds
