## 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 price-basket-observations-duplicate-key-report-numeric-row-ordering-8921b24e -d '<json body>'
```

Example prompt: I have a list of price basket observations with row IDs, regions, dates, item prices, and quantity weights — can you run a duplicate key report and numeric row ordering on them, sorted by item_price?

## When to prefer this

Choose this endpoint when you need fast, local analytical checks on price basket observation data — specifically duplicate key detection and numeric ordering — without requiring live market lookups, predictions, or external data enrichment. Ideal for data quality audits before import or analysis pipelines, especially when working with economics or retail basket datasets of up to 200 rows at very low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (row_id, region, date, item_price, or quantity_weight) — validation error
- Invalid date format (must match YYYY-MM-DD pattern)
- field enum value not one of 'item_price' or 'quantity_weight' — rejected
- Numeric values outside allowed range (-1e12 to 1e12) — schema rejection
- Empty rows array (minItems: 1 required)

## How this service works

Price basket observations — Duplicate key report + Numeric row ordering: Duplicate key report + Numeric row ordering for supplied price basket observations records (item_price, quantity_weight). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two reports: (1) a duplicate key report identifying any row_ids that appear more than once in the input, and (2) a numeric row ordering ranking all rows by the selected field (item_price or quantity_weight). Covers up to 200 rows per call with no external lookups.
