## 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 commercial-proposal-comparisons-record-quality-audit-equal-width-458d1983 -d '<json body>'
```

Example prompt: Can you run a record quality audit and equal-width histogram on these 12 commercial proposal records — use quoted_amount as the field and 8 bins — here are the rows with row_id, company_group, date, quoted_amount, and delivery_days for each supplier?

## When to prefer this

Choose this endpoint when you need both a data quality audit and a distribution histogram on commercial proposal comparison data (quoted_amount, delivery_days) in a single low-cost call. It is ideal for procurement analysts doing pre-review data hygiene checks on up to 200 supplier proposal rows without needing external lookups, live pricing feeds, or predictive models. Prefer alternatives if you need predictions, external enrichment, or more than 200 rows.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, company_group, date, quoted_amount, delivery_days) per row causes rejection
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- bins value outside 1–30 range is rejected
- All-null values for the selected field may produce degenerate histogram output
- Malformed JSON body returns a 4xx error

## How this service works

Commercial proposal comparisons — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied commercial proposal comparisons records (quoted_amount, delivery_days). 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 independent reports: (1) a record quality audit identifying missing, null, or out-of-range values per row for quoted_amount and delivery_days, and (2) an equal-width histogram showing bin edges and counts for the selected field (quoted_amount or delivery_days) across all supplied rows, using the specified number of bins (1–30).
