# Job Listing Inventories — Duplicate Key Report + Equal-Width Histogram

> Job Listing Inventories — Duplicate Key Report + Equal-Width Histogram 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).

Analyzes up to 200 job listing inventory rows to produce a duplicate key report and an equal-width histogram for either listing_count or 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-duplicate-key-report-equal-width-histogram-e5c22112 -d '<json body>'
```

Example prompt: Can you run a duplicate key report and an equal-width histogram (5 bins) on my job listing inventory data — focusing on the listing_count field — for these rows: row-1 group-a 2026-10-01 listing_count=10 duplicate_listings=1, row-2 group-b 2026-10-02 listing_count=20 duplicate_listings=2, row-3 group-a 2026-10-03 listing_count=15 duplicate_listings=3?

## When to prefer this

Choose this endpoint when you need both a duplicate key audit and a histogram distribution summary on job listing inventory data in a single low-cost call. It is best suited for offline batch quality checks on structured tabular data (up to 200 rows) where no live data lookups, predictions, or external integrations are required. Prefer it over general analytics tools when your data is already in the required row format with listing_count and duplicate_listings fields.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, company_group, date, listing_count, duplicate_listings) causes rejection
- Invalid date format (non-YYYY-MM-DD) triggers a pattern validation error
- bins value outside 1–30 range causes schema validation failure
- Null values in the target numeric field may be excluded from histogram computation
- Payment failure via x402 protocol blocks request processing

## How this service works

Job listing inventories — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram 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 rows sharing the same key fields within the supplied data, and (2) an equal-width histogram showing the frequency distribution of the chosen numeric field (listing_count or duplicate_listings) across the specified number of bins — all computed locally on the supplied rows with no external lookups.
