How this service works
Sports prediction markets across Polymarket and Kalshi in one call — game lines, futures, and props (NFL/NBA/MLB/NHL/soccer/tennis/etc). Optionally narrow with league (a tag/category keyword, e.g. nfl, soccer, world-cup) and cap with limit. Each hit is tagged with its venue and returns the question, live YES/NO price (implied probability), USD volume, close date, and the venue URL. Read-only, keyless.
Output
A list of sports prediction market entries, each tagged with venue (Polymarket or Kalshi), market question text, live YES price and NO price as implied probabilities, USD trading volume, market close date, and a direct URL to the market on the venue.
Example use cases
Example prompt
“Pull the top 10 NFL prediction markets from Polymarket and Kalshi right now — I want to see the question, live YES/NO probabilities, volume, and close dates.”
