# Job Listing Inventories — Numeric Distribution & Two-Measure Correlation

> Job Listing Inventories — Numeric Distribution & Two-Measure Correlation 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 numeric distribution statistics and a two-measure correlation report for up to 200 rows of job listing inventory data (listing_count and duplicate_listings).

## 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-distribution-two-measure-correlation-433764b6 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and correlation analysis on my job listing inventory data? I have up to 50 rows with listing_count and duplicate_listings per company group — analyze the distribution of listing_count and show me how it correlates with duplicate_listings.

## When to prefer this

Choose this endpoint when you need fast, self-contained statistical analysis (distribution + correlation) on a batch of up to 200 job listing inventory records without any external data lookup or prediction. It is ideal for recruitment analytics pipelines, data quality audits of job boards, or HR dashboards that need quick descriptive statistics on listing_count and duplicate_listings fields at very low cost ($0.01 per call for two reports).

## Known failure modes

- Exceeds 200-row limit — request rejected or truncated
- Missing required fields (row_id, company_group, date, listing_count, or duplicate_listings) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in numeric fields may affect statistical completeness
- Invalid field enum value — schema rejection
- Empty rows array — no data to analyze

## How this service works

Job listing inventories — Numeric distribution + Two-measure correlation: Numeric distribution + Two-measure correlation 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) a numeric distribution summary (e.g. min, max, mean, median, percentiles, std dev) for the selected field across supplied rows, and (2) a two-measure correlation report between listing_count and duplicate_listings. Both reports are computed locally using shared analytical engines on the supplied data with no external lookups.
