workflow.run_spread_reader
shallowio.github.SKalinin909/tradingcalc · Verify this server
Reads the same real-world bet's live price from 2-4 prediction-market venues at once (Kalshi, Polymarket, ADI Predictstreet) and reports the spread between the cheapest and most expensive. The caller supplies each venue's own identifier for what they've confirmed is the same underlying bet; this tool never auto-matches events across venues, only reads and compares prices for identifiers you provide. Use when user asks "is this bet priced differently on Kalshi vs Polymarket?" or "which venue has the best price on this?". Returns: quotes[] (venue, identifier, label, probabilityPct, available, error), availableCount, cheapestVenue, mostExpensiveVenue, spreadPct (percentage points, null if fewer than 2 quotes resolved).
