Suspensions are the rhythm of in-play betting: markets blink off during every drive-deciding play and reopen seconds later at repriced numbers. For programmatic consumers the operational rule is that absence of a price is information - a book pulling a market while others still quote it often front-runs a line move across the whole market.
ParlayAPI's live feed reflects books pulling and reposting prices as it happens - with sub-5-second freshness on major sports, a suspension shows up as the price disappearing from that book's entry and returning repriced. Streaming delivery (WebSocket/SSE, Business tier and up - see pricing) is built for reacting to exactly these transitions; try the live demo.
