## 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-category-frequencies-equal-width-histogram-5773ea24 -d '<json body>'
```

Example prompt: Analyze my business directory coverage data — I have 4 rows with listed_entities and verified_entities per company group (group-a and group-b) dated October 2026, and I want both a category frequency report and an equal-width histogram using 5 bins on the listed_entities field.

## When to prefer this

Choose this endpoint when you have up to 200 business directory coverage records and need both a category frequency breakdown by company group and a numeric distribution histogram for listed or verified entity counts in a single low-cost call. It is ideal for quick offline analytics on supplied data without any external API calls or live lookups. Prefer this over generic analytics tools when your data fits the specific schema (listed_entities, verified_entities, company_group, date) and you want two reports for a flat $0.01 fee.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum row limit
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) in any row — validation error
- bins value outside 1–30 range — rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- All values null for selected field — histogram may be empty or degenerate
- Payment of 0.01 USDC not completed — 402 response

## How this service works

Business directory coverage — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram 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: (1) a category frequencies report showing how often each company group appears across the supplied rows, and (2) an equal-width histogram report dividing the chosen numeric field (listed_entities or verified_entities) into the specified number of bins with counts per bin. Both reports are computed locally from the supplied data with no external lookups.
