Streaming APIPrice Feed

​
Added

  • Subscribe by gameID, league, or sport on the price feed. Clients connected to wss://streaming-api.4casters.io/price-stream can now send JSON subscribe, unsubscribe, and subscribeAll commands to narrow the feed to specific games, leagues, or sports. See Subscriptions for the full command shape and routing semantics.
  • parentGameID fanout. Subscribers of a parent gameID also receive updates for child games whose parentGameID matches (e.g. F5-MLB derivatives reach subscribers of the parent game).

​
Changed

  • Backwards compatible. Clients that never send a subscribe command stay in broadcast-all mode and receive every update as before — no integration changes required.
