## 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-duplicate-key-report-e773cc9c -d '<json body>'
```

Example prompt: Check this batch of shipment cost records for duplicate row IDs — I have about 50 rows with fields like row_id, carrier, date, weight_kg, and shipping_cost, and I need a duplicate key report to find any collisions before I import the data.

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01 USDC) local duplicate-key check on shipment cost records specifically, without needing external enrichment or forecasting. Ideal as a lightweight pre-import or ETL validation step for batches of up to 200 rows.

## Known failure modes

- Batch exceeds 200 rows — request rejected with validation error
- Missing required fields (row_id, carrier, date, weight_kg, shipping_cost) — record rejected
- Date field does not match YYYY-MM-DD pattern — validation failure
- Empty rows array (minItems: 1 violated) — request rejected
- Payment of 0.01 USDC not completed — 402 Payment Required response
