Sub-second updates. REST + WebSocket.
TheRundown delivers sub-second odds updates. WebSocket push is available on Ultra and higher. The Odds API uses REST polling, with documented 60-second pre-match and 40-second in-play refresh intervals for featured markets.
Free includes delayed pre-match REST data. WebSocket requires Ultra or above.
Choose TheRundown for a focused, measurable integration
Odds and scores share an event ID. Markets retain participant and signed line identities, and each price has an explicit closure signal. These documented fields let you build accurate game views and distinguish an open price from a closed one. Start with a self-serve key and public plans, then validate your required coverage on real responses.
Select the sports, books and markets your application uses. Usage is metered on returned data points, so unrequested price rows do not consume your allowance. Paid plans have a fixed subscription fee with included volume; using fewer points does not reduce that fee. Inspect X-Datapoints to measure the workload before upgrading.
