# Job Listing Inventories — Equal-Width Histogram & Keyed Dataset Comparison

> Job Listing Inventories — Equal-Width Histogram & Keyed Dataset Comparison 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 an equal-width histogram and a keyed dataset comparison report for up to 200 job listing inventory records (listing_count, duplicate_listings) using local analytical engines.

## 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-equal-width-histogram-keyed-dataset-comparison-33e455a2 -d '<json body>'
```

Example prompt: Can you run a histogram with 10 bins on our job listing inventory data for listing_count, and also compare it against last month's dataset? Here are the rows: row-1, group-a, 2025-01-01, listing_count=120, duplicate_listings=5; row-2, group-b, 2025-01-02, listing_count=340, duplicate_listings=12 — use the same rows for the comparison dataset for now.

## When to prefer this

Choose this endpoint when you need both a distributional view (histogram) and a record-level comparison (keyed diff) of job listing inventory data in a single call, without requiring any external API lookups or predictions. Ideal for periodic audits comparing two snapshots of listing data, or for understanding how listing counts or duplicate listings are spread across company groups, all for a flat $0.01 per call covering up to 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected
- Missing required fields (row_id, company_group, date, listing_count, duplicate_listings) — validation error
- bins parameter outside 1–30 range — rejected
- Numeric values outside ±1,000,000,000,000 — schema violation
- Malformed date strings not matching YYYY-MM-DD — validation error
- Empty rows array — rejected

## How this service works

Job listing inventories — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison 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 analytical reports: (1) an equal-width histogram showing bin boundaries and row counts for the selected numeric field (listing_count or duplicate_listings), and (2) a keyed dataset comparison showing per-row-ID differences between the primary and secondary datasets. No external data is fetched; all computation is local.
