x-guidance: GET /api/observed lists the followed matches with their Win/Lose prices (status 3 and observed.inProgress = open, before observed.closesAt). GET /api/agents/config gives the chain, USDC, match contract and fees. To take a position, sign an ICARE Portfolio action calling placePrediction(matchId, outcome, stake) (outcome 0 = Win, 1 = Lose, stake 1.00 to 50.00 USDC in 6-decimal units), POST it to /api/agents/bets, then pay the returned x402 challenge (stake + 0.20 USDC) with an EIP-3009 authorization. The open-source MCP server (npx -y github:Djangode/icare-mcp) does all of this for an agent wallet.
