Choose a sport, bookmaker region and market type, then compare outcome definitions and timestamps before using the data as a reference for a prediction contract.

Supported data includes moneyline, spreads, totals, selected futures, player props and alternate lines. Decimal or American odds are available alongside teams, start times, bookmaker-update timestamps and supported scores or results. Coverage and refresh intervals vary by sport, book and market. Use REST for an application or Excel and Google Sheets add-ons for a spreadsheet workflow. Eligible plans offer past snapshots, whose availability differs from free current-odds access. A useful comparison still needs the same event and settlement definition, an explicit bookmaker-margin adjustment and a snapshot available before the historical decision time. ### Who it is for - For developers building sports-price comparisons and researchers studying historical bookmaker lines. - For spreadsheet users maintaining a sports dashboard without writing their own API client. ## Data and API methods - **Bookmaker and market selection** Choose supported regional books and moneyline, spread, total, selected futures, prop or alternate-line markets; request decimal or American odds. - **Metadata, scores and history** Read teams, starts and bookmaker-update times, retrieve supported results and query available historical snapshots on eligible plans. - **API or spreadsheet access** Integrate REST data in code or use the offered Excel and Google Sheets add-ons. ## Integration tasks ### Construct a reference probability Match the event and settlement terms, retrieve both sides and remove bookmaker margin with a specified method before comparing a prediction contract. ### Avoid a later snapshot For a historical entry, use an available snapshot from before the entry time and inspect its bookmaker timestamps. ### Budget polling credits Estimate consumption across chosen markets and regions, then monitor remaining usage and the actual refresh cadence. ## Pricing and total cost Starter provides 500 monthly credits for free. The documented paid tiers increase quota; endpoint coverage and historical eligibility still need to match the selected plan. ### Starter Free - 500 credits/month - Sports, bookmakers and markets depend on the selected endpoints ### 20K $30/month - 20,000 credits/month - Sports, bookmakers and markets depend on the selected endpoints ### 100K $59/month - 100,000 credits/month - Sports, bookmakers and markets depend on the selected endpoints ### 5M $119/month - 5,000,000 credits/month - Sports, bookmakers and markets depend on the selected endpoints ### 15M $249/month - 15,000,000 credits/month - Sports, bookmakers and markets depend on the selected endpoints ## API access and setup 1. Choose API or spreadsheet access and request an API key. 2. Set sport, region and market type, then inspect outcome definitions and update timestamps. 3. Estimate credit costs and monitor quota and refresh cadence before broad polling. ## Useful links ### What to check - Coverage and refresh intervals vary by sport, bookmaker and market. Historical access differs from the free current-odds offering. - Credit costs depend on the requested data; one HTTP call is not always one credit. The service supplies data rather than executing bets. A closer look ## Ratings & reviews Editorial rating **4.0**/ 5 0 user reviews PredictionToolkit editorial ### Our take on The Odds API Defined bookmaker coverage, timestamps and historical endpoints make this a useful external sports-price reference. Integration still needs checks for quota consumption, varying refresh intervals and quotes that are not executable prediction-market orders. **Assessment criteria:** Task usefulness, documented scope, setup clarity, and access and cost transparency. **Assessment date:** 2026-10-05 **Documentation reviewed:** 2026-10-01 Documentation-based assessment.
