# Job Listing Inventories — Numeric Row Ordering & IQR Outlier Flags

> Job Listing Inventories — Numeric Row Ordering & 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 2026-10-15).

Ranks rows numerically and flags IQR-based outliers for job listing inventory data (listing_count, duplicate_listings) across up to 200 supplied records.

## 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-iqr-outlier-flags-8fbb9522 -d '<json body>'
```

Example prompt: Can you rank these job listing records by listing_count and flag any IQR outliers? I have 4 rows: row-1 group-a 2026-10-01 listing_count=10 duplicate_listings=1, row-2 group-b 2026-10-02 listing_count=20 duplicate_listings=2, row-3 group-a 2026-10-03 listing_count=15 duplicate_listings=3, row-4 group-b 2026-10-04 listing_count=30 duplicate_listings=4.

## When to prefer this

Choose this endpoint when you have up to 200 rows of job listing inventory data and need both a numeric ranking and IQR-based outlier detection in a single call, without requiring any external data sources or live lookups. It is ideal for QA pipelines, recruitment analytics dashboards, or periodic audits of job board data where statistical anomaly flagging on listing_count or duplicate_listings is needed cheaply at $0.01 per call.

## Known failure modes

- Fewer than 1 row supplied — minItems constraint violation
- More than 200 rows supplied — maxItems constraint violation
- Missing required fields (row_id, company_group, date, listing_count, duplicate_listings) on any row
- Date field does not match YYYY-MM-DD format pattern
- Numeric field values outside allowed range (-1e12 to 1e12)
- Invalid field enum value (must be listing_count or duplicate_listings)
- Insufficient data spread for meaningful IQR calculation (e.g., all identical values)

## How this service works

Job listing inventories — Numeric row ordering + IQR outlier flags: Numeric row ordering + 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

Two analytical reports for the supplied rows: (1) numeric ordering of all records ranked by the selected field (listing_count or duplicate_listings), and (2) IQR-based outlier flags identifying which rows fall outside the interquartile range threshold — all computed locally with no external lookups.
