by Compound Returns in Markets & finance

x402 APIPassing, checked 1 h ago

Compound a list of period returns into a total growth factor. Call when multi-period performance rollups from return series you already have. Returns compounded factor and total return 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.
