## 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-string-normalisation-equal-width-histogram-9eace5d4 -d '<json body>'
```

Example prompt: Analyse my job listing inventory data — I have 4 rows with company groups 'group-a' and 'group-b', listing counts and duplicate listings for dates in October 2026. Run string normalisation and an equal-width histogram with 5 bins on the listing_count field.

## When to prefer this

Choose this endpoint when you have tabular job listing inventory data (up to 200 rows) and need both string normalisation and an equal-width frequency histogram in a single call without any external lookups, live data fetching, or ML predictions. It is ideal for offline, local analytical processing of supplied data where you control the number of bins and the target numeric field.

## Known failure modes

- More than 200 rows submitted — request rejected, reduce row count
- Invalid date format (not YYYY-MM-DD) — schema validation error
- bins value outside 1–30 range — request rejected
- Missing required fields (row_id, company_group, date, listing_count, duplicate_listings) — validation error
- Non-numeric values in listing_count or duplicate_listings — may be treated as null or cause error
- Empty rows array — request rejected

## How this service works

Job listing inventories — String normalisation + Equal-width histogram: String normalisation + 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

Two analytical reports: (1) a string normalisation report for the text fields in the supplied job listing inventory rows, and (2) an equal-width histogram report for the selected numeric field (listing_count or duplicate_listings) broken into the specified number of bins, covering up to 200 rows of supplied data.
