If your product needs prices from many bookmakers in one call — odds-comparison sites, multi-book arb scanning breadth — an aggregator like SportsGameOdds does what a dedicated feed can't. Just model the object-billing cost at your real polling rate first.
Need the sharp reference price fast, with drop alerts and predictable cost? That's PinnWire. Need breadth across dozens of books more than speed on one? That's an aggregator. For arbitrage you likely want both — one fast sharp leg, one wide net.
PinnWire is a dedicated Pinnacle-only feed with push delivery (WebSocket + SSE) and flat-rate pricing. SportsGameOdds is a multi-book aggregator — Pinnacle among many books — served by polling with object-based billing at last check.
They're complementary: arbitrage needs multiple books. Many builders use a dedicated sharp feed like PinnWire for the fast-moving Pinnacle reference leg, and an aggregator for the slower legs. Check how quickly the aggregator refreshes Pinnacle prices before relying on it for the sharp side.
PinnWire is flat-rate (rate-limited, unlimited volume on Pro and up, $89–219/mo at last check). SportsGameOdds bills by objects returned on tiers from roughly $99 to $499/mo at last check — heavy polling multiplies cost.
