Looking for a reliable sports betting API that provides real-time odds, live scores, and match data across multiple sports. Ideally similar to Bet365.

Any recommendations for good providers?

I think Kalshi and Polymarket offer a free API. Not sure if that's what you're looking for.

ESPN has a free API with live scores, match data, and betting odds across multiple sports. No API key needed, but it’s unofficial/undocumented.

Bet365 has no public API, so anything "Bet365-like" is either scraped data or a reseller. What I've seen work:

• BetsAPI, the closest to what you want. It has Bet365 endpoints (prematch + inplay odds, results, events), plus a lot of niche stuff like eSoccer and eBasketball that most providers ignore. Paid, but solid uptime.
• The Odds API, easiest to start with, has a free tier and covers a lot of bookmakers in one call. Good for comparing prices, weaker on live/in-play.
• API-Football (api-sports), great for fixtures, live scores, lineups and stats, with a free daily quota. Odds are there but limited.
• Sportmonks, similar idea, more polished, pricier.

Kalshi/Polymarket are prediction markets, not bookmaker odds, so prices won't match a sportsbook. ESPN's endpoint is fine for scores but it's undocumented and can change without warning.

My advice: pick by what you actually need. Odds comparison → The Odds API. Bet365 lines specifically → BetsAPI. Scores/stats → API-Football. And always store the data yourself, live odds move fast and APIs go down at the worst moment.
