PAID ($0.005/call). Polymarket prediction markets HostDeFi tracks (top ~100 by 24h volume): market ids, questions, latest yes/no odds and sampling stats from HostDeFi's own recorded series. Call once WITHOUT x402_payment to receive the x402 payment requirements (an accepts array); pay one of them with any x402 client/wallet, then call again with x402_payment set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
