> Knowledge Base Maintenance — Record Quality Audit + Numeric Row Ordering 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).

Runs two analytical reports on knowledge base maintenance records: a data quality audit and a numeric row ordering report for up to 200 rows of updated_articles and due_articles data.

## 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 knowledge-base-maintenance-record-quality-audit-numeric-row-ordering-4e7f875c -d '<json body>'
```

Example prompt: Can you run a record quality audit and numeric row ordering report on these knowledge base maintenance rows — I have data for document groups A and B with updated_articles and due_articles counts across October 2026, up to about 50 rows, and I want the report for the updated_articles field?

## When to prefer this

Choose this endpoint when you need both a data quality audit and a numeric ordering report for knowledge base maintenance records in a single low-cost call. It is ideal for offline/batch validation of article tracking datasets (up to 200 rows) where no live lookup, prediction, or external data enrichment is needed. It is not appropriate for real-time monitoring, machine learning predictions, or datasets larger than 200 rows.

## Known failure modes

- rows array is empty or missing — validation error
- row count exceeds 200 — request rejected
- date field does not match YYYY-MM-DD pattern — validation error
- field enum value not one of updated_articles or due_articles — rejected
- numeric values outside ±1,000,000,000,000 range — rejected
- missing required fields (row_id, document_group, date) in any row — error

## How this service works

Knowledge base maintenance — Record quality audit + Numeric row ordering: Record quality audit + Numeric row ordering for supplied knowledge base maintenance records (updated_articles, due_articles). 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 record quality audit identifying data issues such as nulls, out-of-range values, or formatting problems in the specified field across the supplied rows, and (2) a numeric row ordering report ranking rows by the selected field (updated_articles or due_articles). Both reports are generated locally from supplied data with no external lookups.
