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.

DonBest pricing explained
No current public DonBest API tier price was verified for this comparison. The cited XML/ActiveMQ documentation is dated September 2013 and describes an integration format, not current commercial terms. Confirm present-day access, coverage, and pricing directly with the provider.
TheRundown monthly plans are Free, Starter $49, Pro $149, and Ultra $399, with higher-volume tiers available. Free is pre-match REST from DraftKings, FanDuel, and BetMGM with a five-minute delay. Starter is delayed 60 seconds; Pro 30 seconds. Real-time REST and WebSocket begin on Ultra. Commercial end-user display begins on Pro.
TheRundown combines a fixed subscription fee with included data-point volume. Select only the sports, books, and markets you need: unrequested price rows do not consume that volume, but the base fee still applies. X-Datapoints reports billed usage. Requests, credits, event objects, and data points are different units. Monthly and annual plans stop at included limits by default; optional overage and weekly billing have separate terms.

Which provider fits your project?
Why choose TheRundown
TheRundown may suit a new JSON REST/WebSocket integration with published tiers. Porting an existing XML or ActiveMQ consumer requires a data-model and transport change.
When to evaluate DonBest
Existing DonBest customers should confirm their current contract and feed specification. A legacy XML guide alone cannot establish the capabilities or price of today’s service.
