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.

What developers say
Odds API with broad bookmaker and sport coverage, used by developers for arbitrage tools, football research bots and benchmarks. Praised for global coverage, but users report 404/500 errors on some historical Betfair markets and limited NBA history starting late 2025, and some ask about gaps and latency. Compared with The Odds API and BoltOdds.
