# Business Location Inventories — Adjacent Row Changes + Two-Measure Correlation

> Business Location Inventories — Adjacent Row Changes + Two-Measure Correlation 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).

Computes adjacent row-over-row changes and Pearson/rank correlation between location_count and verified_locations for up to 200 supplied business location inventory records, returning two independent analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 business-location-inventories-adjacent-row-changes-two-measure-3b6e2f9a -d '<json body>'
```

Example prompt: I have a dataset of up to 200 business location inventory records with columns row_id, company_group, date, location_count, and verified_locations — can you run the adjacent row changes report and the two-measure correlation report on it, focusing on location_count?

## When to prefer this

Choose this endpoint when you have up to 200 rows of business location inventory data already in hand and need both sequential delta analysis (adjacent row changes) and a correlation between two location metrics in a single low-cost call. It is ideal for offline/batch analytical workflows where no live data lookup, external enrichment, or prediction is needed — just pure statistical computation on supplied records.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected with row limit error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Missing required fields (row_id, date, location_count, verified_locations) — rejected
- Null values in both measures preventing correlation computation — may return NaN or error
- Payment of 0.01 USDC not included — 402 Payment Required

## How this service works

Business location inventories — Adjacent row changes + Two-measure correlation: Adjacent row changes + Two-measure correlation for supplied business location inventories records (location_count, verified_locations). 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) an adjacent row changes report showing the difference in the selected measure (location_count or verified_locations) between consecutive records, and (2) a two-measure correlation report quantifying the statistical relationship between location_count and verified_locations across all supplied rows. Results are computed entirely from the submitted data with no external lookups.
