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: 'expectancy' (a float representing the average expected profit/loss per trade, e.g. 2.6), 'n' (number of trades analyzed), and 'schema' (version identifier 'delx/util-expectancy/v1').
Example use cases
Algo strategy edge verification
“I backtested my algo and got these trade PnLs: [12, -5, 8, -3, 15, -7, 10]. Can you calculate the expectancy so I know if my strategy actually has a statistical edge?”
Day trader performance review
“Here are my last 20 trade results in dollars: [45, -20, 30, -15, 50, -10, 25, -30, 60, -5, 40, -25, 35, -8, 55, -12, 20, -40, 70, -3]. What's my trading expectancy?”
Risk manager evaluating a new signal
“We're reviewing a new trading signal and here are its historical PnLs: [-2, 5, -1, 8, 3, -4, 6]. Compute the expectancy so we can decide whether to allocate capital to it.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/expectancy?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.001 USDC) computation of trading strategy expectancy from a raw list of PnL values, without requiring account signup. Prefer over custom implementations when you want a pay-per-result model with verifiable delivery on Base or Solana via the x402 payment protocol.
Side effects

- Non-numeric values in the pnls array may cause a computation failure
- Payment not confirmed (x402 flow incomplete) results in 402 response
- Malformed request body returns a 400 error
