## 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 promotion-observations-exact-row-deduplication-numeric-row-ordering-853dad47 -d '<json body>'
```

Example prompt: Can you deduplicate and numerically order these promotion observation records for me — I have up to 50 rows with discount_amount and units_sold fields across several store groups, and I need 2 clean analytical reports back?

## When to prefer this

Choose this endpoint when you have raw promotion observation tabular data (with discount_amount and units_sold) that needs exact duplicate row removal and numeric ordering without any live data lookup, external prediction, or professional assessment — and you want two compact analytical reports for up to 200 rows at minimal cost ($0.01 USDC).

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, store_group, date, discount_amount, units_sold) — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- Empty rows array — minimum 1 item required
- Numeric values out of allowed range (±1,000,000,000,000) — schema rejection

## How this service works

Promotion observations — Exact row deduplication + Numeric row ordering: Exact row deduplication + Numeric row ordering for supplied promotion observations records (discount_amount, units_sold). 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

Returns two analytical reports covering exact row deduplication (identifying and removing fully duplicate rows) and numeric row ordering applied to the supplied promotion observation records (discount_amount and units_sold fields), based entirely on the provided dataset with no external lookups.
