Returns each venue's top matches normalized to { venue, title, implied_probability (0-1 for the main/YES outcome, or null), url, n_outcomes }, plus a divergence summary across venues' top matches. HONESTY: this surfaces WHERE TO LOOK for mispricing — it is NOT an executable-arb tool. A high spread_pp usually reflects different bet shapes, resolution criteria, dates, thin liquidity, or each venue's own trading fees (Polymarket and Kalshi both charge a taker fee that varies by category/price — see the polymarket_edges/polymarket_arbitrage tools for the modeled schedule; this scanner does not net any of them out), not a real arbitrage. Divergence is only computed when ≥2 venues' top titles share strong token overlap (Jaccard); otherwise divergence is null with a low-match-quality note telling you to compare manually. Verify the questions resolve identically before trading.
