## 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 damaged-stock-quality-audit-equal-width-histogram-22602d46 -d '<json body>'
```

Example prompt: Can you run a quality audit and equal-width histogram on my damaged stock data — I have 4 rows with store groups A and B, handled_units and damaged_units per day from 2026-10-01 to 2026-10-04, and I want the histogram to use 5 bins on the damaged_units field?

## When to prefer this

Choose this endpoint when you need a combined data quality audit and distribution histogram for damaged stock records in a single low-cost call, and your dataset is 200 rows or fewer. It is ideal for retail or warehouse analysts who want to validate record completeness and understand the shape of handled or damaged unit distributions before reporting or downstream processing. It does not perform live lookups, forecasting, or external integrations.

## Known failure modes

- More than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- Missing required fields (row_id, handled_units, damaged_units) — schema error
- Bins parameter out of range (must be 1–30) — validation error
- Empty rows array — request rejected
- Payment of 0.01 USDC not completed — 402 response

## How this service works

Damaged stock — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied damaged stock records (handled_units, damaged_units). 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 independent reports: (1) a record quality audit identifying data issues such as nulls, out-of-range values, or malformed entries across the supplied rows; and (2) an equal-width histogram showing bin edges and counts for the selected field (handled_units or damaged_units) using the specified number of bins (1–30). No external lookups or predictions are performed — all analysis is local and deterministic.
