## 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-summary-trailing-mean-series-931315bd -d '<json body>'
```

Example prompt: I have 150 rows of brand mention data with company groups, dates, mention_count and source_count — can you give me a grouped numeric summary plus a trailing mean series using a window of 7 for mention_count?

## When to prefer this

Use this endpoint when you have up to 200 rows of brand mention inventory records and need both a grouped descriptive summary and a rolling/trailing mean time series in a single API call. Ideal for batch offline analysis of brand monitoring data where no live lookup or external enrichment is needed. Prefer this over single-report endpoints when you want both grouped statistics and trend series at once for the same dataset.

## Known failure modes

- Fewer than 1 row supplied — minimum 1 row required
- More than 200 rows supplied — request exceeds row limit
- Window size larger than number of data points per group — trailing mean may be sparse or empty
- Invalid date format (must be YYYY-MM-DD) — row rejected or error returned
- Missing required fields (row_id, company_group, date) — validation error
- Numeric values outside allowed range (-1e12 to 1e12) — rejected
- Invalid field enum value (must be 'mention_count' or 'source_count') — error returned

## How this service works

Brand mention inventories — Grouped numeric summary + Trailing mean series: Grouped numeric summary + Trailing mean series 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 (e.g. mean, min, max, count) of the selected field broken down by company_group, and (2) a trailing mean time series for the selected field using the specified window size. Both reports are computed locally from the supplied rows, with no external data lookup.
