## 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-record-quality-audit-trailing-mean-series-fbec728a -d '<json body>'
```

Example prompt: Can you run a record quality audit and trailing mean series on these brand mention records — I have 50 rows with mention_count and source_count per company group by date, use a window of 7, and focus the trailing mean on mention_count?

## When to prefer this

Choose this endpoint when you need both a data quality audit and a trailing mean time series computed together on brand mention inventory data (mention_count or source_count) in a single low-cost call. It is ideal for offline/batch analytical use on already-collected data without needing live data feeds, predictions, or external enrichment. Best suited for datasets up to 200 rows processed locally.

## Known failure modes

- More than 200 rows supplied — request rejected due to maxItems limit
- Invalid date format in rows — must match YYYY-MM-DD pattern
- Missing required fields (row_id, company_group, date, mention_count, source_count) causes validation error
- Window size outside 2–200 range returns an error
- Numeric values outside ±1,000,000,000,000 boundary may be rejected
- Empty rows array (minItems 1 not met) causes rejection

## How this service works

Brand mention inventories — Record quality audit + Trailing mean series: Record quality audit + 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 reports: (1) a record quality audit highlighting issues such as nulls, out-of-range values, or malformed dates across the supplied rows, and (2) a trailing mean time series for the selected numeric field (mention_count or source_count) computed with the specified window size — all derived locally from the supplied data with no external lookups.
