From public data checked . How we know
Choose ParlayAPI if you…
Odds API
Best for: Developers building odds, props and arbitrage tools for internal use, with streaming and low entry prices.
- ✓ want to start on a free tier
- ✓ want a lower entry price ($5/mo vs $65/mo)
Not ideal for: Public or customer-facing products, resale or white-label without a signed agreement; self-serve plans are internal-use only.
What developers say
Young odds aggregator pitched as a cheaper drop-in for The Odds API, with a free 1,000-credit tier, prediction-market books and MCP tooling. Nearly everything found is vendor-written posts, directory submissions or the founder's own repos. No independent user feedback on reliability, accuracy or support, so little is actually 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.
