Compare the same event contract across Polymarket, Kalshi, and Limitless side-by-side: probability, liquidity, settlement rules, and venue type. Use when the user wants to know "what's the spread between Polymarket and Kalshi on X" or "which venue has better liquidity for Y". Returns match confidence buckets (high/medium/low) and explains any mismatches. Real-money venues only — Manifold is excluded because play-money pricing isn't comparable to real-money.

}Browse trending, high-volume, fast-moving, or high-disagreement prediction markets across Polymarket, Kalshi, Limitless, and Manifold.

For cross-venue queries use `search_markets` or `compare_markets`.

Use for analytical queries like "what do markets think about the 2028 election", "odds on a Fed rate cut", or "how is crypto priced for year-end". Returns top markets by volume, cross-venue divergences, venue coverage, and risk flags. For raw market lists use `search_markets`.

| min_volume | number | Minimum 24h USD volume per market. Real-money markets with missing volume data are kept but tagged with risk_flag 'volume_unconfirmed'. Sentiment markets (Manifold) are exempt — their volume is denominated in Mana, not USD. Set to 0 to disable. |

}Surface cross-venue price discrepancies between Polymarket, Kalshi, and Limitless as a discovery feed for price discovery and divergence detection. Default threshold is 0.5% spread, below typical round-trip fees — most results are informational, not tradable arbitrage. Raise `min_spread` to 0.03+ for after-fee opportunities. The optional `query` parameter post-filters results by topic keywords on event titles — it does not perform a topic search; for topic-driven retrieval use `discover_markets` or `search_markets`. Pairs with missing volume data on at least one venue are flagged 'volume_unconfirmed'. All results are indicative only — not trade recommendations. Real-money venues only. Orderbook depth is not confirmed in Phase 1.
| Argument | Type | Description |
|---|---|---|
| limit | number | |
| query | string | Optional post-filter on event titles by topic keywords (e.g. 'crypto', 'election', 'fed'). This filters the discovery feed locally — it is not a topic search and may return zero results when today's biggest discrepancies don't overlap your topic. Omit to receive the full feed. |
| min_spread | number | Minimum price gap to report (0.005 = 0.5%, 0.03 = 3 percentage points). Default 0.005 surfaces price discovery signals, most of which are below typical 4% round-trip fees and therefore informational rather than tradable. Raise to 0.03+ to filter for after-fee opportunities. |
| min_volume | number | Minimum 24h USD volume on the thinner side of each pair. Pairs where at least one venue has missing volume data are kept but tagged with risk_flag 'volume_unconfirmed'. Set to 0 to disable. |
