## 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-daily-sum-series-adjacent-row-changes-41d436a9 -d '<json body>'
```

Example prompt: Can you run two reports on my business directory coverage data — a daily sum series and adjacent row changes — for listed_entities? I have 4 rows: 2026-10-01 group-a 10 listed/1 verified, 2026-10-02 group-b 20/2, 2026-10-03 group-a 15/3, 2026-10-04 group-b 30/4.

## When to prefer this

Choose this endpoint when you have pre-collected business directory coverage data (listed and verified entity counts by date and company group) and need two complementary analytical views — a daily aggregate sum series plus adjacent row-level change detection — in a single low-cost call. Ideal for offline batch analysis of up to 200 rows without requiring live data lookup, external enrichment, or prediction capabilities.

## Known failure modes

- Missing required fields (row_id, date, company_group) cause validation errors
- Dates not matching YYYY-MM-DD pattern are rejected
- More than 200 rows submitted exceeds the limit and returns an error
- Null values in listed_entities or verified_entities may affect sum/delta calculations
- Invalid field enum value (anything other than listed_entities or verified_entities) causes rejection
- Payment failure via x402 protocol results in no response

## How this service works

Business directory coverage — Daily sum series + Adjacent row changes: Daily sum series + 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 derived from the supplied rows: (1) a daily sum series aggregating the selected field (listed_entities or verified_entities) by date across company groups, and (2) adjacent row changes showing the delta between consecutive rows for the selected field. Results are computed locally on supplied data only, with no external lookups or predictions.
