# Job Listing Inventories — Exact Row Deduplication + Two-Measure Correlation

> Job Listing Inventories — Exact Row Deduplication + 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 2026-10-23).

Deduplicates job listing inventory rows and computes correlation between listing_count and duplicate_listings across up to 200 supplied records, returning two 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-exact-row-deduplication-two-measure-correlation-ceb1aaa6 -d '<json body>'
```

Example prompt: Can you deduplicate my job listing inventory rows and then run a correlation between listing_count and duplicate_listings? I have about 50 rows across company groups like 'group-a' and 'group-b' with dates in October 2026 — I need both the dedup report and the correlation report back.

## When to prefer this

Use this endpoint when you have tabular job listing inventory data (up to 200 rows) and need both exact-duplicate row removal and a Pearson-style correlation between listing_count and duplicate_listings in a single API call. It is ideal for offline batch data-quality checks on recruitment or HR datasets where no live external data, prediction, or external action is required. Prefer it over general-purpose analytics tools when you want a low-cost ($0.01 USDC), self-contained computation on supplied data without any side effects.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, date, listing_count, duplicate_listings) cause validation failure
- Malformed date strings not matching YYYY-MM-DD pattern rejected
- Null values in both numeric measures may prevent meaningful correlation computation
- Fewer than 2 unique rows may result in degenerate correlation output

## How this service works

Job listing inventories — Exact row deduplication + Two-measure correlation: Exact row deduplication + Two-measure correlation 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: (1) a deduplicated version of the input rows with exact duplicates identified and removed, and (2) a two-measure correlation report quantifying the statistical relationship between listing_count and duplicate_listings across the supplied records.
