## 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-benchmark-correlation-a2fe2d98 -d '<json body>'
```

Example prompt: I have 4 retail products with list prices of $100, $110, $100, $110, percentage discounts of 30%, 33%, 30%, 33%, and maximum discount caps of $20, $22, $20, $22 — please compute how the resulting capped-coupon prices correlate with the benchmark series [10, 20, 30, 40].

## When to prefer this

Use this endpoint when you need a statistical correlation report between retail prices after applying a capped percentage discount and a set of benchmark values, specifically for supplied retail data (not live market rates). Prefer this over general statistics APIs when the capped coupon pricing formula (min of percentage discount vs flat cap) is the exact transformation needed before correlation.

## Known failure modes

- Fewer than 2 rows or benchmark values provided — minimum array size violation
- Row objects missing required fields (list_price, discount_percent, maximum_discount) — schema validation error
- Arrays exceed 200 items — maxItems constraint violated
- Mismatched array lengths between rows and benchmarks may produce unexpected correlation results
- Negative list prices or discount percentages outside 0–100 range — schema minimum/maximum violations
- Payment not completed or insufficient USDC balance — 402 Payment Required
