## 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-average-entry-price-calculator-b05a68df -d '<json body>'
```

Example prompt: Calculate my average entry price for a position where I have fills like [{price: 10, size: 2}, {price: 12, size: 1}, {price: 13, size: 1}].

## When to prefer this

Use this endpoint when you need a quick, pay-per-use computation of volume-weighted average entry price from a list of trade fills without setting up any account or subscription. It is ideal for agents operating in trading, DeFi, or portfolio management contexts that need cost-basis calculations on the fly, paid in USDC via the x402 protocol.

## Known failure modes

- Empty or missing fills array returns an error or undefined result
- Non-numeric price or size values in fills cause computation failure
- Malformed JSON body rejected with 400-level error
- Payment failure via x402 protocol blocks request execution
- Zero-size fills may cause division errors or be silently ignored
