## 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 first-attempt-delivery-share-record-ranking-89493b47 -d '<json body>'
```

Example prompt: I have a list of shipment batches — can you rank them by their first-attempt delivery share? Here are four records: batch A had 100 attempted shipments and 87 first-attempt deliveries, batch B had 110 attempted with 95.7 delivered on first try, batch C had 200 attempted with 160 delivered, and batch D had 50 attempted with 48 delivered.

## When to prefer this

Choose this endpoint when you need a straightforward, ranked comparison of multiple retail shipment records by first-attempt delivery rate and have the raw counts (attempted shipments and first-attempt deliveries) on hand. It is best suited for batch ranking of 2–200 records at $0.01 USDC per call with no need for live logistics platform access or order execution.

## Known failure modes

- Fewer than 2 records provided — minimum array length is 2
- More than 200 records submitted — maxItems limit exceeded
- attempted_shipments value is 0 or negative — exclusiveMinimum:0 violated
- first_attempt_deliveries exceeds attempted_shipments — logically invalid ratio
- Non-numeric values passed in numeric fields — schema validation failure
