## What it does

One tool, ten calculators an LLM should not do in its head: black\_scholes, implied\_volatility, kelly, sharpe, sortino, max\_drawdown, historical\_var, cvar, cagr, volatility. Args: function, params \(e.g. kelly {p, b}; black\_scholes {S, K, T, r, sigma, type}\).

## How to buy

```text
PAID ($0.003/call): call_service({ id: "svc_64d3be32-5ced-4d2d-89fb-02132b0088dd", args }) — the 402 lists ONE x402 payment = the FULL price straight to the seller (FiatDock takes 0% of this listing's calls right now); the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays it automatically. This remote /mcp returns the 402 challenge. You are charged only if the seller actually answers. To learn what to put in arguments, call get_service({ id: "svc_64d3be32-5ced-4d2d-89fb-02132b0088dd", includeSchemas: true }) first — it returns toolSchemas (argument names and types). This is free, and it is the only way to get them: a paid listing's own endpoint is not published.
