# Job Listing Inventories — Base-100 Series + Equal-Width Histogram

> Job Listing Inventories — Base-100 Series + 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).

Generates a Base-100 indexed time series and an equal-width histogram for job listing inventory data (listing_count or duplicate_listings) from up to 200 supplied 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-base-100-series-equal-width-histogram-a8338bba -d '<json body>'
```

Example prompt: Take my job listing inventory data — 4 rows with listing_count and duplicate_listings — and give me a Base-100 indexed series for listing_count starting from row index 0, plus an equal-width histogram with 5 bins.

## When to prefer this

Choose this endpoint when you have up to 200 rows of job listing inventory records (listing_count or duplicate_listings) and need both a normalized time-indexed trend (Base-100 series) and a statistical distribution view (equal-width histogram) in a single low-cost call. Prefer it over generic analytics APIs when you want offline/local computation on supplied data with no external data fetching, and when the cost-per-call matters at $0.01 USDC for two reports simultaneously.

## Known failure modes

- More than 200 rows submitted — request rejected
- base_index out of range for supplied row count
- Invalid date format (must be YYYY-MM-DD)
- Missing required row fields (row_id, company_group, date, listing_count, duplicate_listings)
- bins value outside 1–30 range
- Base row value is null or zero causing division error in Base-100 calculation
- Payment not received or insufficient USDC — 402 response

## How this service works

Job listing inventories — Base-100 series + Equal-width histogram: Base-100 series + 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 analytical reports: (1) a Base-100 indexed series where each row's selected field value is expressed relative to the value at the specified base_index row, and (2) an equal-width histogram breaking the selected field's value distribution into the specified number of bins with counts per bin. Both reports are computed locally on the supplied data with no external lookups.
