Notes

Over MCP, ask for it in plain English and the client calls get_market_odds itself. Point any MCP client at https://mcp.fastballapi.com/mcp?key=YOUR_API_KEY.
Each call costs 10 credits, taken before it runs and refunded if the server errors.
Not the call you need? Find the right call by what you are trying to answer.
