## Frequently Asked Questions

### What is the difference between Odds-API.io and OddsMarket?

OddsMarket is an enterprise odds feed provider: XML feeds from 300+ sportsbooks (their claim), sold through a sales process with pricing on request. Odds-API.io is a self-serve developer API: REST JSON and WebSocket, published pricing, and plans from £49/month, so you can integrate the same day.

### Is Odds-API.io a good OddsMarket alternative for developers?

Yes, if you prefer JSON over XML and self-serve over sales calls. You get 415+ bookmakers, 34 sports, 12,000+ leagues, pre-match and live odds, WebSocket streaming, plus built-in value bets and arbitrage endpoints. If your organization specifically needs XML feeds or a managed enterprise contract, OddsMarket may be a better fit.

### Does OddsMarket have a free tier?

OddsMarket advertises a free trial for their odds monitoring tool, but their odds feed pricing is not published and requires contacting them. Odds-API.io publishes its pricing: New free API keys on Odds-API.io are paused; existing free keys keep working. The entry plan is Solo at £49/month: 2 bookmakers of your choice, 5,000 requests/hour, every sport and market, pre-match and live. Cancel anytime.

### Which is better for arbitrage betting?

Both cover arbitrage. OddsMarket offers arbitrage detection as part of its product lineup, and Odds-API.io ships a dedicated arbitrage endpoint alongside a value bets endpoint. The practical difference is access: with Odds-API.io you can start testing arbitrage data the same day you subscribe, while OddsMarket requires going through their sales process for feed access.

### Can I switch from an XML odds feed to Odds-API.io?

Yes. Odds-API.io serves the same kind of data (pre-match and live odds across bookmakers) as REST JSON endpoints and a WebSocket stream, which most modern stacks handle with less parsing code than XML. Monthly plans with no lock-in make it easy to run both in parallel while you migrate.
