Sports
Active sports games with urgency scores and cross-provider prices
Returns active game IDs plus, when the provider indexing gate has predictfun enabled, open Predict.fun fixtures inside their scheduled start/end window. The gate is re-checked on every request (including cache hits); a gate lookup failure excludes Predict.fun (fail closed) without dropping Polymarket/Kalshi rows. Hydrates current state, drops ended games idle for more than a few minutes, and computes an urgencyScore/stale flag per game. Enriches each event with cached primary-market data, falling back to a live provider lookup when the cache is cold. Resolves each event’s matching Polymarket/Kalshi slug and attaches the corresponding cross-venue match record into matchingMarkets. If no matched entry anywhere carries a Kalshi side, synthesizes one from a team-name-matching fallback lookup. Results are sorted by most-recent update, then by urgencyScore descending. Served from a shared server cache rebuilt about every 5 seconds while the endpoint is in use and never more than 60 seconds old; the Age header gives the seconds since the body was built.
