## 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-grouped-numeric-summary-keyed-dataset-878ee6f8 -d '<json body>'
```

Example prompt: I have two sets of job listing inventory records — each with company group, date, listing count, and duplicate listings — and I want a grouped numeric summary by company group plus a side-by-side keyed comparison between the two datasets, analyzing the listing_count field, for up to 200 rows.

## When to prefer this

Choose this endpoint when you have structured job listing inventory data in hand and need both a grouped statistical summary and a dataset-to-dataset keyed comparison in a single call. Ideal for recruitment analytics pipelines, duplicate listing audits, or period-over-period inventory comparisons where no live data lookup or external API is needed. Not suitable for fetching live job data or making predictions.

## Known failure modes

- Missing required fields (row_id, company_group, date, listing_count, or duplicate_listings) cause validation errors
- Exceeding 200 rows results in rejection or truncation
- Invalid date format (not YYYY-MM-DD) triggers schema validation failure
- Null numeric values may affect aggregate computations
- Mismatched row_ids between primary and comparison datasets reduce keyed comparison coverage

## How this service works

Job listing inventories — Grouped numeric summary + Keyed dataset comparison: Grouped numeric summary + 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 independent analytical reports: (1) a grouped numeric summary aggregating listing_count or duplicate_listings by company_group across the supplied rows, and (2) a keyed dataset comparison between the primary rows and the secondary 'other' dataset, highlighting differences per matching key. All computation is performed locally with no external lookups.
