Z-score of spread series for pairs trading. Call when mean-reversion signals from a price-spread series. Returns zscore, mean, stdev as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
One-command purchase
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
