Pack: market-spread · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/compare_topic for the schema, then POST the same URL with its arguments for the data.

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.

Parameters

`topic`	string	yes	Topic / question to scan across venues, e.g. “bitcoin 100k”, “fed rate cut”, “2028 president”, “government shutdown”, “trump”.
`per_venue`	number	no	Top matches to show per venue (default 3, max 5).
