}Who is buying the prediction-market line. Polymarket wallet records, the market board (who is in, per market), GT line vs Smart-money line gaps, and the smart-money entry feed. Counts from the Polygon chain, each with its sample size. Paid per call over x402 (USDC on Base or Solana), or free to connect over MCP.
The memecoin tools are paused; everything below is prediction-market data.
/x402/... is the always-402 door a bazaar validator probes. /v1/pm/... answers the free rows without a
payment and a 402 for the rest. Same prices, one constant in the worker.
Sign the requirement and send the payload back in PAYMENT-SIGNATURE (any x402 client does this; @x402/fetch works):
Each market comes back with its sides, price, $ and wallets, the tagged wallets holding each side (SMART MONEY / WHALE / BOT/MM), the GT line and the Smart-money line. No sportsbook odds and no Kalshi price ever ride these routes.
