Choose Betfair Exchange API if you…
Betting exchange
Best for: Developers building trading bots or tools on the Betfair betting exchange who need order books and bet placement.
- ✓ want to start on a free tier
- ✓ value a large open-source ecosystem of wrappers and examples
- ✓ care most about what developers report in practice
Not ideal for: Projects that need a general sports data feed or non-Betfair odds; the API only exposes the Betfair exchange.
What developers say
The standard exchange API for betting bots and trading tools, with long-standing wrappers and many automation projects. Users complain about restricted access: regional blocks (Brazil), certificate login hurdles, and a reported live-key fee of around 500 pounds. Many seek third-party feeds or historical data instead.

What developers say
UK betting exchange with a free streaming/REST API, mentioned as a Betfair alternative for arbitrage and trading bots, and cited as a lay-price source in odds aggregators. Evidence is mostly old: a 2010 launch, and a metaforecast issue about missing contracts in market data. Little current opinion.
