## 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-daily-sum-series-iqr-outlier-flags-575e390a -d '<json body>'
```

Example prompt: Analyze my brand mention inventory data for two company groups — run the daily sum series and IQR outlier detection on mention_count for these rows: group-a had 10 mentions on 2026-10-01 from 1 source and 15 mentions on 2026-10-03 from 3 sources; group-b had 20 mentions on 2026-10-02 from 2 sources and 30 mentions on 2026-10-04 from 4 sources.

## When to prefer this

Choose this endpoint when you have pre-collected brand mention inventory records (up to 200 rows) and need both a daily aggregated sum series and IQR-based statistical outlier detection in a single low-cost call ($0.01 USDC for 2 reports). Ideal for offline/batch brand monitoring analytics where you supply your own data and want fast local computation without any external data lookups or live brand tracking. Not suitable for real-time brand monitoring, fetching live mention data, or processing more than 200 rows at once.

## Known failure modes

- Missing required fields (row_id, company_group, date, mention_count, source_count) cause validation errors
- Input exceeding 200 rows is rejected
- Malformed date strings not matching YYYY-MM-DD pattern cause schema validation failure
- Numeric values outside ±1,000,000,000,000 bounds are rejected
- Empty rows array is rejected (minItems: 1)
- Invalid field enum value (only 'mention_count' or 'source_count' accepted)

## How this service works

Brand mention inventories — Daily sum series + IQR outlier flags: Daily sum series + IQR outlier flags 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 daily sum series showing aggregated values of the selected field (mention_count or source_count) by date and company group, and (2) IQR-based outlier flags identifying which data points fall outside the interquartile range, for up to 200 supplied rows — all computed locally without external data lookups.
