Tools (1)

| Tool | Description | |---|---| | win-prob | (0.003 USDC/call) Estimates live in-game win probability for NFL, NBA, MLB, NHL, and soccer from the current score and time remaining. Returns each team's win probability, the projected final margin, the size of the swing still possible, and human-readable drivers. Built-in scoring volatility for NFL/NCAAF/NBA/NCAAB/WNBA/MLB/NHL/soccer; override scoring_std for any sport. Statistical estimate, not betting advice. Use it as a live sports win probability API or in-game win chance calculator. |

How it works

1. Agent calls a tool (e.g. win-prob).
2. MCP server POSTs to https://x402.agentutility.ai/win-prob.
3. The endpoint responds HTTP 402 with payment instructions.
4. The MCP server signs an EIP-3009 USDC transfer authorization with X402_PRIVATE_KEY and retries.
5. CDP facilitator settles on Base.
6. The endpoint returns the actual response.

The agent never sees the payment flow — it just gets the result.
