## 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 price-after-capped-percentage-coupon-weighted-result-mean-a2adf981 -d '<json body>'
```

Example prompt: I have 4 retail items with list prices of $100, $110, $100, and $110, each with a 30–33% discount capped at $20–22, and weights of 1, 2, 1, 2 — can you calculate the weighted mean price customers actually pay after the capped coupon?

## When to prefer this

Use this endpoint when you need a statistically weighted aggregate (mean) of post-coupon prices across multiple retail items where the percentage discount has a hard dollar cap — particularly when individual rows have different importance weights such as sales volume or inventory share. Prefer this over a simple average when rows are not equally significant.

## Known failure modes

- Fewer than 2 rows submitted — minimum row count not met
- Weights array length does not match rows array length
- list_price, discount_percent, or maximum_discount missing from a row — required fields validation error
- Values exceeding maximum bounds (e.g. list_price > 1e12) rejected
- More than 200 rows submitted — exceeds maxItems limit
- Payment not received or insufficient USDC — 402 Payment Required
