The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • scan_discrepancies auth-required 5h ago

    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.

  • search_markets auth-required never probed

    Search live prediction markets and event contracts across Polymarket, Kalshi, Limitless (real-money) and Manifold (sentiment). Use for queries on election odds, political markets, Fed rate decisions, crypto prices, sports outcomes, geopolitics, and other binary markets with crowd-sourced probabilities. Returns unified results with title, current probability, volume, liquidity, expiration, source venue, and risk flags. For topic synthesis use `market_brief`; for browsing trending markets use `discover_markets`.

  • market_brief auth-required never probed

    Generate a synthesized brief for a topic, combining real-money signals from Polymarket, Kalshi, and Limitless with Manifold community sentiment. 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`.

  • discover_markets auth-required 5h ago

    Browse trending, high-volume, fast-moving, or high-disagreement prediction markets across Polymarket, Kalshi, Limitless, and Manifold. Use when the user wants to explore what's happening — "what's hot on Polymarket today", "show me biggest political markets", "what events are ending soon" — rather than search a specific topic. Filter by category and sort by volume, newest, or ending soon.

  • compare_markets auth-required never probed

    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.

  • inspect_platform auth-required never probed

    Inspect a single named venue. Returns available capabilities, market data for the query, and metadata quality flags. Use when the user explicitly names a venue — "show me Polymarket markets on AI", "what's on Kalshi for Q4 inflation", "Manifold markets about geopolitics". For cross-venue queries use `search_markets` or `compare_markets`.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

[![measured by brick.blue](https://brick.blue/api/v1/agents/f2300d68d8c01910/badge.svg)](https://brick.blue/agent/f2300d68d8c01910)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
