How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the number of observations (n), mean return, standard deviation of returns, and the computed Sharpe ratio as a float, along with a schema identifier (delx/util-sharpe-lite/v1) for result verification.
Example use cases
Portfolio strategy performance check
“I've got these monthly returns from my momentum strategy: [0.03, -0.01, 0.02, 0.04, -0.005, 0.015] — can you compute the Sharpe ratio so I know if the risk-adjusted performance is worth it?”
Comparing two trading signals
“Here are the daily returns for my first signal: [0.001, 0.003, -0.002, 0.004]. Calculate the Sharpe ratio so I can compare it against my second signal later.”
Crypto asset risk check
“I have these weekly returns from my ETH holding over the past month: [0.05, -0.03, 0.02, 0.08]. What's the Sharpe ratio — is the volatility worth the return?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/sharpe-lite?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-signup, pay-per-call Sharpe ratio computation without standing up your own quant infrastructure. Ideal for AI agents that need lightweight, on-demand risk-adjusted performance scoring for small return series. Prefer over heavier analytics platforms when latency, cost, and simplicity matter more than advanced metrics like Sortino or Calmar ratios.
Side effects
- Empty or null returns array causes computation failure
- Non-numeric values in returns array produce invalid results
- Insufficient data points (n<2) may yield undefined standard deviation
- Payment via x402 not included or malformed results in 402 response
- Network timeout or service unavailability returns 5xx error
