# Job Listing Inventories — Secondary-Measure Weighted Mean + Explicit Missing-Value Fill

> Job Listing Inventories — Secondary-Measure Weighted Mean + Explicit Missing-Value Fill 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 secondary-measure weighted mean and fills missing values in job listing inventory data (listing_count, duplicate_listings) for up to 200 rows, returning 2 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-secondary-measure-weighted-mean-explicit-52e66e3e -d '<json body>'
```

Example prompt: Calculate the weighted mean of listing_count for these job inventory records — I have 4 rows across two company groups (group-a and group-b) from October 2026 — and fill any missing values using the median method.

## When to prefer this

Choose this endpoint when you have structured job listing inventory data (listing_count and/or duplicate_listings) that needs both weighted mean aggregation by secondary measure and explicit missing-value imputation in a single call. It is purpose-built for recruitment/job board analytics pipelines that require statistically clean summaries without relying on external data sources or live lookups. Prefer this over general-purpose analytics tools when you need deterministic, offline computation with predictable pricing ($0.01 USDC for 2 reports covering up to 200 rows).

## Known failure modes

- More than 200 rows submitted — request rejected with row count exceeded error
- Invalid date format not matching YYYY-MM-DD pattern — validation error
- Missing required fields (row_id, company_group, date) — schema validation failure
- Field enum value not in ['listing_count','duplicate_listings'] — invalid field error
- All values for the chosen field are null — weighted mean may be undefined or returns fill-only result
- Numeric values outside allowed range (-1T to +1T) — validation error

## How this service works

Job listing inventories — Secondary-measure weighted mean + Explicit missing-value fill: Secondary-measure weighted mean + Explicit missing-value fill 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 2 analytical reports per call covering: (1) secondary-measure weighted mean of the chosen field (listing_count or duplicate_listings) across supplied rows, and (2) explicit missing-value fill results using the specified method (zero, mean, or median), applied to up to 200 input rows.
