From public data checked . How we know
Choose PropLine if you…
Odds API
Best for: Developers and bettors who need player-prop and game odds from 100+ books at low monthly prices, in a format close to The Odds API.
- ✓ want to start on a free tier
- ✓ want a lower entry price ($9/mo vs $65/mo)
- ✓ need commercial use allowed in the public terms
Not ideal for: Users needing deep history before April 2026, or teams wanting to resell or republish the data; redistribution is banned.
What developers say
Per-request-billed player-prop and odds API that mimics The Odds API format and grades props against box scores. Digest holds only a Show HN post, directory import and the vendor's own SDK, MCP and tool repos. No independent user opinion on accuracy, limits or cost, so little is known.
Choose Odds-API.io if you…
Odds API
Best for: Odds comparison and betting tools that need pre-match and live odds from many bookmakers, with public USD plans and an optional WebSocket feed.
- ✓ 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 free plan or resale of raw odds; there is no free tier and resale needs written consent.
What developers say
Aggregated odds API with broad bookmaker claims, used in side projects and sportsbook prototypes, and listed in MCP/agent tool collections. User feedback leans negative: live odds delayed by roughly 10 seconds or more, many UK bookmakers shown inactive, and Pinnacle support dropped in January 2026. Seen as an alternative to The Odds API and OpticOdds.
