## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-trading-expectancy-calculator-248fd7c7 -d '<json body>'
```

Example prompt: Calculate the trading expectancy for this list of PnL values: [3.2, -1.5, 4.0, -0.8, 5.1] — I want to know the average expected return per trade.

## When to prefer this

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.

## Known failure modes

- Empty or missing 'pnls' array returns an error
- 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

## 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').

```

## Response schema (JSON Schema)

```json
{
 "type": "json",
 "example": {
