# Job Listing Inventories — Duplicate Key Report + Trailing Mean Series

> Job Listing Inventories — Duplicate Key Report + 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).

Generates two analytical reports (duplicate key detection and trailing mean time series) for up to 200 rows of job listing inventory data, operating entirely on supplied data with no external lookups.

## 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-duplicate-key-report-trailing-mean-series-e197de9f -d '<json body>'
```

Example prompt: Can you run a duplicate key report and trailing mean series on my job listing inventory data — I have 4 rows with listing_count and duplicate_listings fields for groups A and B from October 2026, using a window of 2 — and analyze listing_count?

## When to prefer this

Choose this endpoint when you need simultaneous duplicate key detection AND a trailing moving average on job listing inventory data in a single cheap call ($0.01 USDC). Ideal for batch data quality checks on recruitment datasets up to 200 rows where no live lookup or external data enrichment is needed — purely analytical, fast, and deterministic.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Invalid date format not matching YYYY-MM-DD pattern — validation error
- Missing required fields (row_id, company_group, date, listing_count, duplicate_listings) on any row — schema error
- Window size outside range 2–200 — validation error
- Empty rows array — minItems violation
- Invalid field enum value (not listing_count or duplicate_listings) — schema error

## How this service works

Job listing inventories — Duplicate key report + Trailing mean series: Duplicate key report + 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

Returns two independent analytical reports: (1) a duplicate key report identifying any repeated row_id values in the supplied dataset, and (2) a trailing mean time series computed over the specified numeric field (listing_count or duplicate_listings) using the given window size — both derived entirely from the supplied rows, no external data.
