## 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 style-guide-audits-grouped-numeric-summary-trailing-mean-series-80c6eb4b -d '<json body>'
```

Example prompt: I have 50 style guide audit records with checked_items and flagged_items per document group and date — can you run a grouped numeric summary and a trailing mean series with a window of 5 on flagged_items for me?

## When to prefer this

Choose this endpoint when you have tabular style guide audit data with document group labels and time-stamped rows and need both a grouped aggregate summary and a rolling average trend — all in a single $0.01 call covering up to 200 rows with no external data dependencies.

## Known failure modes

- Missing required fields (row_id, document_group, date, checked_items, flagged_items) cause validation errors
- More than 200 rows submitted exceeds the maximum and will be rejected
- Window size outside the range 2–200 returns an error
- Malformed date strings not matching YYYY-MM-DD pattern fail schema validation
- Null values in both checked_items and flagged_items may produce incomplete statistical outputs

## How this service works

Style guide audits — Grouped numeric summary + Trailing mean series: Grouped numeric summary + Trailing mean series for supplied style guide audits records (checked_items, flagged_items). 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 of the selected field (checked_items or flagged_items) broken down by document_group, including aggregate statistics per group; and (2) a trailing moving-average series computed over the specified window size for the selected field across the date-ordered records. Both reports are generated locally from the supplied data with no external lookups.
