Lite Sharpe Ratio Calculator
x402
Lite Sharpe Ratio Calculator is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Computes a simplified Sharpe-like ratio (mean/stdev) from an array of returns, with no risk-free rate adjustment, for quick risk-adjusted ranking of strategies.

How this service works
Lite Sharpe = mean/stdev of a return sample (no rf, sample). Call when quick risk-adjusted rank of strategy return arrays. Returns sharpe-like ratio and n 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.
Output
Returns a deterministic JSON object containing the Sharpe-like ratio (mean divided by standard deviation of the input returns, no risk-free rate applied, sample stdev) and n (the number of return observations used in the calculation).
Example use cases
Backtest strategy ranking by Sharpe
“I have three strategy return arrays from my backtest — [0.01, 0.02, -0.005, 0.015], [0.03, -0.02, 0.04, 0.01], and [0.005, 0.005, 0.01, 0.008] — can you compute the Sharpe-like ratio for each so I can see which has the best risk-adjusted returns?”
Screening algos before live deployment
“Before I go live with this algo, can you calculate the mean-over-stdev Sharpe score for my out-of-sample returns [0.012, -0.003, 0.022, 0.009, -0.001, 0.018, 0.007, 0.025] to see if the risk-adjusted performance holds up?”
Comparing two portfolio allocations
“I'm deciding between two portfolio allocations — one produced monthly returns of [0.03, 0.01, -0.01, 0.04, 0.02] and the other [0.015, 0.015, 0.014, 0.016, 0.015] — compute the Sharpe-like ratio for each so I can tell which is better risk-adjusted.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/sharpe-liteWhen to prefer
Prefer this endpoint when you need a fast, deterministic, local-math-only Sharpe-like score with no API keys, no live market data, and no risk-free rate adjustment — ideal for quick relative ranking of strategy return arrays in automated pipelines. Use this over full Sharpe implementations when you want a simple mean/stdev ratio, don't need rf-rate adjustment, and want a cheap ($0.001 USDC) deterministic result. Not suitable when regulatory-grade risk metrics or live market feeds are required.
Side effects
- Empty or single-element returns array causes division by zero or undefined stdev
- Non-numeric values in the returns array cause computation failure
- Missing or malformed 'returns' field returns a validation error
- All identical return values produce a stdev of zero, making ratio undefined or infinite
- Payment failure via x402 prevents endpoint access
