# Style Guide Audits — Numeric Row Ordering + Explicit Missing-Value Fill

> Style Guide Audits — Numeric Row Ordering + Explicit Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Sorts style guide audit rows numerically and fills missing checked_items or flagged_items values using zero, mean, or median imputation, returning two reports for up to 200 rows.

## 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-numeric-row-ordering-explicit-missing-value-fill-b9ff322a -d '<json body>'
```

Example prompt: Can you sort these style guide audit rows by numeric order and fill in any missing flagged_items values using median imputation? I have up to 50 rows with fields like row_id, date, document_group, checked_items, and flagged_items — I need two clean reports back.

## When to prefer this

Choose this endpoint when you have style guide audit tabular data with numeric row IDs and need both ordered sorting and missing-value imputation in a single call returning two reports. Ideal for pre-processing audit datasets before downstream analysis or dashboard ingestion, especially when you need a cheap ($0.01 USDC), offline, deterministic transformation without any live lookup or external prediction.

## Known failure modes

- Missing required fields (row_id, document_group, date, checked_items, flagged_items) cause validation errors
- Submitting more than 200 rows exceeds the maximum and will be rejected
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Invalid method enum value (not zero/mean/median) causes a schema error
- Invalid field enum value (not checked_items/flagged_items) causes a schema error
- Payment failure or insufficient USDC balance prevents processing

## How this service works

Style guide audits — Numeric row ordering + Explicit missing-value fill: Numeric row ordering + Explicit missing-value fill 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 covering up to 200 style guide audit rows: one with rows ordered numerically by row identifier, and one with missing values in the specified field (checked_items or flagged_items) explicitly filled using the chosen method (zero, mean, or median). Both reports are computed locally with no external lookups.
