# Job Listing Inventories — Record Quality Audit, String Normalisation & Trailing Mean Series

> Job Listing Inventories — Record Quality Audit, String Normalisation & 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 2026-10-16).

Runs three analytical reports on job listing inventory data: record quality audit, string normalisation, and trailing mean series computation, 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-record-quality-audit-string-normalisation-d35cd192 -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and trailing mean series (window size 7) on my job listing inventory data — I have rows with listing_count and duplicate_listings fields for company groups across the last month?

## When to prefer this

Choose this endpoint when you need a bundled, low-cost ($0.01 USDC) set of three analytical passes — quality audit, string normalisation, and trailing mean — applied to job listing inventory data in a single call. It is ideal for small-to-medium datasets (up to 200 rows) where you want offline/local analysis without external lookups or predictions. Prefer alternatives if you need real-time data fetching, ML-based forecasting, or datasets larger than 200 rows.

## Known failure modes

- Exceeding 200 rows returns an error or truncation
- Missing required fields (row_id, date, listing_count, duplicate_listings) causes validation failure
- Invalid date format (non YYYY-MM-DD) triggers schema rejection
- Window size outside 2–200 range is rejected
- Null-only numeric fields may produce empty trailing mean series
- Payment not included or insufficient USDC causes request rejection

## How this service works

Job listing inventories — Record quality audit + String normalisation + Trailing mean series: Record quality audit + String normalisation + Trailing mean series for supplied job listing inventories records (listing_count, duplicate_listings). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Three independent analytical reports: (1) a record quality audit flagging data issues in the supplied rows, (2) a string normalisation report cleaning text fields, and (3) a trailing mean series for the selected numeric field (listing_count or duplicate_listings) computed over the specified window size — all based solely on the submitted data with no external lookups.
