# Job Listing Inventories — Numeric Row Ordering + Trailing Mean Series

> Job Listing Inventories — Numeric Row Ordering + Trailing Mean Series 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 row ordering and trailing mean series analytics on supplied 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-numeric-row-ordering-trailing-mean-series-2354d7eb -d '<json body>'
```

Example prompt: Run numeric row ordering and a trailing mean series (window size 3) on my job listing inventory data for listing_count — here are 5 rows: row-1 on 2026-10-01 for group-a with listing_count 100 and duplicate_listings 5, row-2 on 2026-10-02 for group-b with 200 and 10, row-3 on 2026-10-03 for group-a with 150 and 8, row-4 on 2026-10-04 for group-b with 250 and 12, row-5 on 2026-10-05 for group-a with 175 and 6.

## When to prefer this

Choose this endpoint when you have up to 200 rows of job listing inventory data and need both numeric row ordering (ranking) and a trailing mean time series computed locally without any external data lookups, predictions, or live data fetching. It is ideal for lightweight, deterministic, reproducible analytics at low cost ($0.01 per call covering both reports).

## Known failure modes

- Fewer than 1 row supplied — validation error
- More than 200 rows supplied — rejected, maxItems limit exceeded
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Window size larger than number of rows — trailing mean may return nulls or partial results
- Missing required fields (row_id, date, listing_count, duplicate_listings) — schema validation error
- Invalid field enum value — rejected

## How this service works

Job listing inventories — Numeric row ordering + Trailing mean series: Numeric row ordering + Trailing mean series 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 per call: (1) a numeric row ordering (rank sequence) applied to the supplied rows, and (2) a trailing mean series computed over the specified numeric field (listing_count or duplicate_listings) using the given window size. Results are derived purely from the supplied data with no external lookups.
