## 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-sequential-input-change-attribution-b1d8e81d -d '<json body>'
```

Example prompt: Run a sequential input-change attribution on my coupon redemption share — before, I had 100 issued coupons and 15 redeemed; after, I have 110 issued and 16.5 redeemed. Show me which input change contributed more to the shift in redemption rate.

## When to prefer this

Choose this endpoint when you need a structured, per-input waterfall decomposition of how coupon issuance volume versus redemption volume each drove a change in the overall redemption share rate. It is purpose-built for retail coupon analytics with only two input variables and produces a single bounded attribution report per call at minimal cost. Prefer it over general statistics or BI tools when you need a fast, auditable attribution without platform access or live data feeds.

## Known failure modes

- issued_coupons must be greater than 0 (exclusiveMinimum); zero value returns validation error
- redeemed_coupons exceeding issued_coupons may produce out-of-range redemption share values
- missing required fields (issued_coupons or redeemed_coupons in either before or after object) returns schema validation error
- values exceeding 1,000,000,000,000 are rejected by maximum constraint
- identical before and after inputs yield a zero-change attribution report
