# Job Listing Inventories — Daily Sum Series + Secondary-Measure Weighted Mean

> Job Listing Inventories — Daily Sum Series + 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 2026-10-23).

Computes a daily sum series and a secondary-measure weighted mean for supplied job listing inventory records (listing_count, duplicate_listings), returning two analytical reports for up to 200 rows.

## 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-daily-sum-series-secondary-measure-weighted-5af7efad -d '<json body>'
```

Example prompt: I have a set of job listing inventory records with listing_count and duplicate_listings by date and company group — can you compute the daily sum series and secondary-measure weighted mean for listing_count across up to 200 rows?

## When to prefer this

Choose this endpoint when you have pre-collected job listing inventory records and need both a daily aggregated sum series and a weighted mean of a secondary measure in a single low-cost call. It is ideal for offline batch analytical reporting on hiring or job board data where no live lookups, predictions, or external enrichment are required. It is not suitable for real-time data retrieval, forecasting, or enrichment from external sources.

## Known failure modes

- Rows array empty or missing — validation error returned
- More than 200 rows submitted — request rejected at maxItems limit
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Field enum value not one of listing_count or duplicate_listings — rejected
- Numeric values outside ±1,000,000,000,000 range — schema violation
- All null values for selected field — weighted mean may be undefined or zero

## How this service works

Job listing inventories — Daily sum series + Secondary-measure weighted mean: Daily sum series + 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

Two independent analytical reports: (1) a daily sum series showing aggregated totals of the selected field grouped by date, and (2) a secondary-measure weighted mean computed across the supplied rows — both derived entirely from the submitted data with no external lookups.
