## 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 warehouse-pick-accuracy-sequential-input-change-attribution-52088cd2 -d '<json body>'
```

Example prompt: Run a waterfall attribution report on our warehouse pick accuracy — before we had 100 total picks and 98 correct picks, and after we had 110 total picks and 107.8 correct picks. Show me how each input change contributed to the accuracy shift.

## When to prefer this

Use this endpoint when you need to decompose a change in warehouse pick accuracy into its sequential contributing factors (total picks volume vs. correct picks count) between two time periods, specifically for retail fulfillment data. Prefer this over generic analytics tools when you want a structured, bounded waterfall attribution report at low cost for up to 200 records.

## Known failure modes

- correct_picks exceeds total_picks — may return validation error or nonsensical accuracy
- total_picks of zero or negative — rejected by exclusiveMinimum constraint
- exceeding 200 records limit — request refused or truncated
- missing required before/after fields — schema validation failure
- non-numeric input values — type validation error
