/**
 * PredictionMarket — unified access to Polymarket / Kalshi / cross-platform
 * matching / smart-money endpoints via the BlockRun gateway. Each call
 * settles via x402 against the user's USDC wallet.
 *
 * Powered server-side by Predexon; surfaced to the agent as a single
 * action-dispatched tool so the inventory stays small. Keep one cohesive
 * tool — the way TradingMarket bundles 6 actions — instead of forty
 * one-shot capabilities, otherwise weak models start hallucinating tool
 * names.
 *
 *   searchPolymarket   $0.001  query Polymarket markets (event filter, sort)
 *   searchKalshi       $0.001  query Kalshi markets
 *   crossPlatform      $0.005  matching market pairs across Polymarket+Kalshi
 *                              (the arbitrage / consensus signal)
 *   smartMoney         $0.005  smart-money positioning on one Polymarket
 *                              condition_id (top wallet flow + side bias)
 *
 * Output is filtered + truncated on the way back so a single call never
 * dumps 100 markets into the agent's context. Default 20 rows; agents that
 * need more should narrow the search.
