## 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 shipment-costs-grouped-numeric-summary-e94f1e9e -d '<json body>'
```

Example prompt: Can you group these shipment records by carrier and give me a numeric summary of their shipping costs? I have 4 records: row-1 on 2026-10-01 carrier group-a weight 10kg cost $1, row-2 on 2026-10-02 carrier group-b weight 20kg cost $2, row-3 on 2026-10-03 carrier group-a weight 15kg cost $3, row-4 on 2026-10-04 carrier group-b weight 30kg cost $4 — summarize the shipping_cost field.

## When to prefer this

Use this endpoint when you have raw shipment records (up to 200) and need a quick grouped numeric summary by carrier without setting up your own aggregation pipeline. It is ideal for lightweight analytics tasks where you want per-carrier aggregate statistics on shipping cost or weight, at very low cost ($0.01 USDC per call). Prefer it over general analytics services when you already have structured shipment data ready and need a fast, bounded computation.

## Known failure modes

- Empty or missing rows array returns an error
- Row count exceeds 200 items — request rejected
- Missing required fields (row_id, carrier, date, weight_kg, shipping_cost) cause validation failure
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Invalid field enum value (not weight_kg or shipping_cost) causes rejection
- Payment not included or insufficient USDC causes 402 response
