## 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-base-100-index-series-e90016b1 -d '<json body>'
```

Example prompt: I have brand mention data for two company groups across a few dates — can you give me a grouped numeric summary and a Base-100 index series for mention_count, using row index 0 as the base? The records are: row-1, group-a, 2024-01-01, mention_count=100, source_count=5; row-2, group-b, 2024-01-01, mention_count=200, source_count=10; row-3, group-a, 2024-01-02, mention_count=150, source_count=7.

## When to prefer this

Choose this endpoint when you have pre-collected brand mention inventory data (up to 200 rows) and need both a grouped aggregate summary and a Base-100 normalized time series in a single low-cost call. It is ideal for offline/batch analytical reporting on brand tracking datasets without needing live data fetches, external API calls, or prediction services. Best suited for competitive intelligence dashboards, campaign measurement, and brand share trend analysis across company groups.

## Known failure modes

- Fewer than 1 row submitted — minItems constraint violation
- More than 200 rows submitted — maxItems constraint violated, request rejected
- Invalid date format (not YYYY-MM-DD pattern) causes row rejection
- base_index out of range (must be 0–199 and within submitted row count)
- Null values in mention_count or source_count may affect summary completeness
- Invalid field enum value (must be 'mention_count' or 'source_count')
- row_id missing or exceeding 80 characters causes schema validation failure

## How this service works

Brand mention inventories — Grouped numeric summary + Base-100 series: Grouped numeric summary + Base-100 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 independent analytical reports: (1) a grouped numeric summary of the selected field (mention_count or source_count) broken down by company_group and date, and (2) a Base-100 index series anchored at the specified base_index row, showing relative change over time. Both reports are computed locally without external lookups.
