# Job Listing Inventories — Record Quality Audit + String Normalisation + Two-Measure Correlation

> Job Listing Inventories — Record Quality Audit + String Normalisation + Two-Measure Correlation 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 (record quality audit, string normalisation, and two-measure correlation) on up to 200 rows of job listing inventory data containing listing_count and duplicate_listings fields.

## 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-two-0f3b7b0c -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and correlation analysis on my job listing inventory data? I have 4 rows: row-1 for group-a on 2026-10-01 with listing_count 10 and duplicate_listings 1, row-2 for group-b on 2026-10-02 with listing_count 20 and duplicate_listings 2, row-3 for group-a on 2026-10-03 with listing_count 15 and duplicate_listings 3, and row-4 for group-b on 2026-10-04 with listing_count 30 and duplicate_listings 4.

## When to prefer this

Choose this endpoint when you have structured job listing inventory data (with listing counts and duplicate counts per company group and date) and need offline, privacy-safe analytical reports without any external data lookups or live predictions. Ideal for data quality pipelines, pre-reporting audits, or when you want correlation insights between listing volume and duplication rate for up to 200 rows at very low cost ($0.01 USDC for all three reports).

## Known failure modes

- More than 200 rows submitted — request rejected due to row limit
- Missing required fields (row_id, date, listing_count, or duplicate_listings) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- All listing_count or duplicate_listings values are null — correlation report cannot be computed
- Empty rows array — minimum 1 row required

## How this service works

Job listing inventories — Record quality audit + String normalisation + Two-measure correlation: Record quality audit + String normalisation + Two-measure correlation 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 completeness, validity, and consistency issues across rows; (2) a string normalisation report standardising company_group and other string fields; and (3) a two-measure correlation report quantifying the statistical relationship between listing_count and duplicate_listings. All computed locally with no external lookups.
