# 预测市场

Find Polymarket and Kalshi markets on an event, read current odds and compare equivalent markets across venues.

**When to use:** The user wants market-implied probabilities for an event or to compare prediction markets.

Requires the `agentrouter` skill (or the AgentRouter MCP server at `http://localhost:3000/api/mcp`) and the `AR_KEY` environment variable.

## Capabilities

- Use `search_capabilities` with the task keywords.

Inspect a capability before the first call: parameters and prices are listed there.

## Steps

1. Search markets for the event on each venue.
2. Read prices as implied probabilities; note liquidity.
3. Present matched markets side by side; never place trades.

## Cost

Each successful call is billed at the price shown by `inspect_capability`; failed calls are free. Quote first when you plan more than ~20 calls, and keep within the budget the user agreed.
