## 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 unit-fill-rate-record-ranking-c9dae971 -d '<json body>'
```

Example prompt: I have four retail records — one with 100 ordered and 95 fulfilled, one with 200 ordered and 160 fulfilled, one with 50 ordered and 50 fulfilled, and one with 300 ordered and 210 fulfilled — can you rank them by unit fill rate from best to worst?

## When to prefer this

Use this endpoint when you have a set of retail records with ordered and fulfilled unit counts and want to rank or compare them by fill rate locally without needing live inventory access, platform integration, or order execution. Ideal for quick scenario analysis, benchmarking suppliers, or scoring SKUs against each other using supplied figures only.

## Known failure modes

- Fewer than 2 rows provided — minimum of 2 records required
- ordered_units is 0 or missing — division by zero not permitted (exclusiveMinimum: 0)
- More than 200 rows submitted — exceeds maxItems limit
- fulfilled_units exceeds ordered_units in extreme scenarios — may produce fill rates above 100%
- Malformed row objects missing required fields fulfilled_units or ordered_units
