RapidOddsAPI vs odds-api.io
An honest comparison of two odds data APIs
odds-api.io is a UK/EU-focused odds API with a large total bookmaker pool and strong coverage of British and European books. If you're comparing it with RapidOddsAPI, this page lays out where each one fits best so you can decide on facts.
The short version: RapidOddsAPI gives you 100+ bookmakers on every paid plan and includes WebSocket at no surcharge, while odds-api.io meters bookmakers by tier and charges double for a push feed. odds-api.io is the better fit if you specifically need its deep UK/EU and betting-exchange coverage. Here's the detail.

Where RapidOddsAPI is stronger
100+ bookmakers on every plan, not metered by tier. odds-api.io paywalls bookmakers by plan: 5 books on Starter, 10 on Growth, and 15 on the £229/mo Pro plan. To get near their headline 265+ figure you need enterprise pricing. RapidOddsAPI gives you 100+ bookmakers on every paid plan, with no per-book gating.
WebSocket included, not a 100% surcharge. odds-api.io charges double your plan price to add WebSocket, so Pro plus WebSocket runs to £458/mo. RapidOddsAPI includes WebSocket on the Pro and Elite plans at no extra cost. For live betting and arbitrage, that is a large, recurring difference.
Built for the Australian market. odds-api.io is centred on UK and European books and lists fewer than five Australian bookmakers. RapidOddsAPI covers 100+ Australian books in depth, which matters if your users bet in Australia.
Standardised data out of the box. Team names, player names and market types arrive already normalised, so prices are directly comparable across books with no mapping layer of your own.
Where odds-api.io is stronger
We'd rather be straight with you than pretend we win on everything:
- Larger total bookmaker pool: 265+ books available at higher tiers, versus our 100+.
- Deeper UK/EU and betting-exchange coverage, including Betfair Exchange, Smarkets and Betdaq.
- More granular request-capacity add-ons if you need very high request volumes.
If your project lives in the UK/EU market or depends on exchange odds, odds-api.io is a reasonable choice and we won't pretend otherwise.
