## 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 job-listing-inventories-numeric-row-ordering-equal-width-histogram-46928090 -d '<json body>'
```

Example prompt: I have 4 job listing records across two company groups with listing counts of 10, 20, 15, and 30 and duplicate listings of 1, 2, 3, and 4 — can you generate a numeric row ordering and equal-width histogram (5 bins) for the listing_count field?

## When to prefer this

Choose this endpoint when you need quick, self-contained statistical analysis (row ranking + frequency distribution) of job listing inventory data without any external lookups or predictions. Ideal for auditing listing volume distributions, identifying duplicate listing concentrations, and generating summary analytics on up to 200 pre-collected job listing records at very low cost ($0.01 per call covering both reports).

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, listing_count, duplicate_listings) — validation error
- Invalid date format (must match YYYY-MM-DD) — schema rejection
- bins value outside 1–30 range — rejected
- All null values in selected field — histogram may be empty or error
- Invalid field enum value — rejected

## How this service works

Job listing inventories — Numeric row ordering + Equal-width histogram: Numeric row ordering + Equal-width histogram for supplied job listing inventories records (listing_count, duplicate_listings). 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: (1) a numeric row ordering of supplied records ranked by the chosen field (listing_count or duplicate_listings), and (2) an equal-width histogram showing frequency counts across up to 30 user-defined bins — all computed locally on the supplied data with no external lookups.
