Built for AI agents

Every prediction market.
One feed for your agent.

huebr reads live odds from Polymarket, Kalshi, PredictIt and Manifold, matches the same question across venues and hands your agent the consensus price, the cheapest place to trade and the gaps worth acting on.

How it works

Ingest

Public market data from Polymarket (live order book stream), Kalshi, PredictIt and Manifold, normalised to YES probabilities with bid, ask and size.

Match

Entity resolution links the same proposition across venues. Years, thresholds and comparators must agree; ambiguous pairs go to human review.

Analyse

Liquidity-weighted consensus, dispersion, cross-venue arbitrage net of each venue's fees, and prices that diverge from the other venues.

Serve

Remote MCP server for agents, REST and server-sent events for code. Everything is served from memory in milliseconds.

Connect your agent

Eight read-only tools: list venues, search markets, compare odds across venues, find arbitrage, find mispricings and fetch price history. Prices are probabilities; a YES contract pays 1 if the event happens.

  • Streamable HTTP, stateless, no session to manage
  • Same data over REST with an OpenAPI spec
  • Server-sent events for Pro keys

Add the remote MCP server. Pass a Pro key to unlock every signal.
