What is an Odds API (Odds Feed)?

Definition: An odds API, or odds feed, is a data service that delivers sports fixtures, betting markets, prices and results to a sportsbook platform in a machine-readable format.

Data in a typical feed:

  • Fixtures and schedules with sport, league and participants.
  • Pre-match and live odds per market and selection.
  • Market status: open, suspended, closed.
  • Live scores and official results for settlement.

Delivery methods:

  • Pull (REST) - the platform requests data at intervals.
  • Push (WebSocket or message queue) - updates arrive as soon as prices change, which live betting requires.

Key considerations: latency, sports coverage, depth of markets, uptime and the speed of suspension signals during live events.
