# Job Listing Inventories — Category Frequencies + IQR Outlier Flags

> Job Listing Inventories — Category Frequencies + IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes category frequencies and IQR-based outlier flags for job listing inventory records (listing_count, duplicate_listings) across up to 200 rows, producing two independent analytical reports.

## 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-category-frequencies-iqr-outlier-flags-d06e5b27 -d '<json body>'
```

Example prompt: Can you analyze these job listing inventory rows for me — I have up to 50 records with company_group, date, listing_count, and duplicate_listings — and give me both the category frequency breakdown and IQR outlier flags for the listing_count field?

## When to prefer this

Choose this endpoint when you have up to 200 rows of job listing inventory data and need both a frequency distribution of a numeric field by category and IQR-based outlier flagging in a single low-cost call. It is ideal for recruitment analytics pipelines, job board quality audits, or HR data validation workflows where you supply your own data and need fast, local statistical analysis without any external data enrichment or prediction.

## Known failure modes

- Fewer than 1 row submitted — minItems constraint violated
- More than 200 rows submitted — maxItems limit exceeded
- Missing required fields (row_id, company_group, date, listing_count, duplicate_listings) on any row
- Invalid date format (must match YYYY-MM-DD pattern)
- Numeric values outside allowed range (±1,000,000,000,000)
- Invalid field enum value (must be 'listing_count' or 'duplicate_listings')
- Payment of 0.01 USDC not attached — x402 payment required

## How this service works

Job listing inventories — Category frequencies + IQR outlier flags: Category frequencies + IQR outlier flags 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 independent analytical reports: (1) category frequency counts showing how listing_count or duplicate_listings values are distributed across company_group categories, and (2) IQR-based outlier flags identifying which rows fall outside the interquartile range for the selected numeric field. Both reports are computed locally with no external lookups.
