# Style Guide Audits — Trailing Mean Series + Secondary-Measure Weighted Mean

> Style Guide Audits — Trailing Mean Series + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Computes a trailing moving-average time series and a secondary-measure weighted mean over supplied style guide audit records (checked_items, flagged_items) for up to 200 rows, returning two independent analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-trailing-mean-series-secondary-measure-weighted-mean-3ce5e96a -d '<json body>'
```

Example prompt: Run a trailing mean series and secondary-measure weighted mean on my style guide audit data — I have 4 rows with checked_items and flagged_items per document group, using a window of 2, and I want results for checked_items.

## When to prefer this

Choose this endpoint when you need both a rolling/trailing mean time series and a weighted mean summary computed together from user-supplied style guide audit data in a single call. It is well-suited for document compliance tracking, editorial quality monitoring, or any scenario where checked_items and flagged_items are the core metrics. Prefer it over generic analytics tools when you want a bundled two-report result at low cost ($0.01 USDC) without any live data lookups or external dependencies.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — request rejected
- Invalid date format (must be YYYY-MM-DD) causes row validation failure
- Window size smaller than 2 or larger than 200 returns an error
- checked_items or flagged_items values outside ±1,000,000,000,000 are rejected
- Missing required fields (row_id, document_group, date) cause schema validation errors
- Field enum value not 'checked_items' or 'flagged_items' causes rejection

## How this service works

Style guide audits — Trailing mean series + Secondary-measure weighted mean: Trailing mean series + Secondary-measure weighted mean 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

Two independent analytical reports: (1) a trailing moving-average time series over the selected field (checked_items or flagged_items) using the specified window size, and (2) a secondary-measure weighted mean across the supplied rows grouped by document_group. Both reports are computed locally from the submitted data with no external lookups.
