## 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 coupon-redemption-share-weighted-result-mean-a9ef0b9e -d '<json body>'
```

Example prompt: Calculate the weighted mean coupon redemption share across these 4 retail periods: period 1 had 100 issued and 15 redeemed (weight 1), period 2 had 110 issued and 16 redeemed (weight 2), period 3 had 200 issued and 30 redeemed (weight 1), period 4 had 150 issued and 22 redeemed (weight 2).

## When to prefer this

Choose this endpoint when you need a single weighted summary statistic for coupon redemption share from your own supplied retail data (up to 200 records), and you want to assign differential importance (weights) to each record. It is appropriate for offline/batch analytical tasks where you supply the raw issued and redeemed counts; it does not provide live rates, order execution, or access to external retail platforms.

## Known failure modes

- Fewer than 2 rows provided — minimum of 2 rows required
- issued_coupons value is zero or negative — exclusiveMinimum enforced
- More than 200 rows submitted — maxItems limit exceeded
- Weights array length does not match rows array length — mismatch error
- Missing required fields issued_coupons or redeemed_coupons in any row
- Payment not provided or insufficient — x402 payment required at $0.01 USDC
