Pack: market-spread · Endpoint: https://gateway.pipeworx.io/market-spread/mcp
Cross-venue prediction-market LANDSCAPE scanner: for one topic, show how 5 venues (Polymarket, Kalshi, Manifold, PredictIt, Futuur) are pricing it side by side and flag divergence. Each venue is queried in parallel; a venue that errors or times out is reported as { reachable: false } and never fails the call. 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.
