## 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 brand-mention-inventories-grouped-numeric-summary-equal-width-histogram-b0c12d43 -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and a 5-bin histogram on my brand mention data? I have records for 'Acme Corp' and 'Globex' with mention_count and source_count values — use mention_count as the field and group by company.

## When to prefer this

Choose this endpoint when you have brand mention inventory data (up to 200 rows) and need both a grouped numeric summary and a histogram in a single call at very low cost ($0.01 USDC). Prefer it over general-purpose analytics tools when you want pre-packaged statistical outputs for brand/media monitoring workflows without writing custom aggregation logic. It is ideal for lightweight exploratory analysis or automated reporting pipelines where offline computation on supplied data is sufficient.

## Known failure modes

- Fewer than 1 row supplied — minimum of 1 row required
- More than 200 rows supplied — exceeds the maxItems limit
- Invalid date format — must match YYYY-MM-DD pattern
- Bins value out of range — must be between 1 and 30
- Missing required fields (row_id, company_group, date, mention_count, source_count) in any row
- Invalid field enum value — must be 'mention_count' or 'source_count'
- Numeric values outside allowed range (±1,000,000,000,000)

## How this service works

Brand mention inventories — Grouped numeric summary + Equal-width histogram: Grouped numeric summary + Equal-width histogram for supplied brand mention inventories records (mention_count, source_count). 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 grouped numeric summary showing descriptive statistics (e.g. mean, min, max, count) for the chosen field (mention_count or source_count) broken down by company_group, and (2) an equal-width histogram showing the frequency distribution of values across a configurable number of bins. Both reports are computed locally on the supplied data — no external lookups are performed.
