From public data checked . How we know
Choose The Odds API if you…
Odds API
Best for: Developers and bettors who want bookmaker odds across many sports and regions from a simple JSON API, with a free tier to test and prepaid-style monthly credit plans.
- ✓ build a betting product and need that allowed in the public terms
- ✓ value a large open-source ecosystem of wrappers and examples
- ✓ care most about what developers report in practice
Not ideal for: Teams that need to resell odds as their own feed or API, which the terms ban, or that need official league data.
What developers say
Widely used for pulling bookmaker odds into fantasy tools, arbitrage scanners and betting models; many GitHub repos and tutorials build on it. Users like the free tier and breadth of markets and books. Complaints: modest refresh rate, historical odds limited to one day per call and gaps in snapshots, no prop results or match outcomes, some books paid-only.

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.
