# Business Directory Coverage — Numeric Row Ordering + Adjacent Row Changes

> Business Directory Coverage — Numeric Row Ordering + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Sorts business directory coverage rows numerically and computes adjacent-row changes for listed_entities and verified_entities across up to 200 records, returning two analytical reports.

## 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-directory-coverage-numeric-row-ordering-adjacent-row-changes-7818c179 -d '<json body>'
```

Example prompt: I have business directory coverage records for two company groups across four dates — can you sort them numerically by row and show me the adjacent row-to-row changes for listed_entities? Here are the rows: row-1 (2026-10-01, group-a, listed=10, verified=1), row-2 (2026-10-02, group-b, listed=20, verified=2), row-3 (2026-10-03, group-a, listed=15, verified=3), row-4 (2026-10-04, group-b, listed=30, verified=4).

## When to prefer this

Choose this endpoint when you have business directory coverage data (listed_entities, verified_entities) already in hand and need fast, local numeric row sorting plus adjacent-row delta computation — no live lookup, enrichment, or external API calls involved. Prefer it over general analytics tools when you specifically need both ordering and row-change reports together in a single low-cost call ($0.01 USDC) for up to 200 rows of directory coverage records.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected with max items error
- Missing required fields (row_id, date, company_group) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation rejection
- Field value outside allowed numeric range — schema rejection
- Invalid field enum value — rejected with enum constraint error

## How this service works

Business directory coverage — Numeric row ordering + Adjacent row changes: Numeric row ordering + Adjacent row changes for supplied business directory coverage records (listed_entities, verified_entities). 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 for the submitted rows: (1) rows sorted in numeric row order, and (2) adjacent row changes (deltas) for the selected field (listed_entities or verified_entities), computed locally without any live lookup or external data enrichment.
