# Job Listing Inventories — Numeric Distribution & Secondary-Measure Weighted Mean

> Job Listing Inventories — Numeric Distribution & Secondary-Measure Weighted Mean 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).

Computes a numeric distribution and a secondary-measure weighted mean for up to 200 job listing inventory records, covering listing_count and duplicate_listings fields.

## 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-secondary-measure-f42b4fe6 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and secondary-measure weighted mean on this job listing inventory data — 4 rows with listing_count and duplicate_listings for groups A and B from October 2026 — analyzing the listing_count field?

## When to prefer this

Choose this endpoint when you need two offline statistical reports — a numeric distribution and a secondary-measure weighted mean — for job listing inventory data (listing_count, duplicate_listings) without any external data lookups. Ideal for batch analytical summarization of up to 200 rows of recruiter or HR inventory data at very low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — only up to 200 rows accepted
- Missing required fields (row_id, company_group, date, listing_count, or duplicate_listings) cause validation errors
- Invalid date format (must match YYYY-MM-DD pattern) results in rejection
- Null values in numeric fields may affect weighted mean computation
- Invalid field enum value (must be listing_count or duplicate_listings) causes error
- Empty rows array not accepted (minItems: 1)

## How this service works

Job listing inventories — Numeric distribution + Secondary-measure weighted mean: Numeric distribution + Secondary-measure weighted mean 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 computed locally: (1) a numeric distribution of the selected field (listing_count or duplicate_listings) across the supplied rows, and (2) a secondary-measure weighted mean using the other field as the weight. Results are based entirely on the submitted data with no external lookup or live data.
