}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.

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.
