## 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-numeric-row-ordering-numeric-interval-filter-f73dd0d4 -d '<json body>'
```

Example prompt: Sort my knowledge base maintenance records by updated_articles and filter to only rows where updated_articles is between 10 and 50 — here are my 4 records: row-1 (group-a, 2026-10-01, updated=10, due=1), row-2 (group-b, 2026-10-02, updated=20, due=2), row-3 (group-a, 2026-10-03, updated=15, due=3), row-4 (group-b, 2026-10-04, updated=30, due=4).

## When to prefer this

Choose this endpoint when you have knowledge base maintenance tabular data (up to 200 rows) and need both a sorted ranking and a numeric interval filter on article counts in a single $0.01 call. Ideal for agents managing KB health dashboards, editorial queues, or content audits that need quick offline analytics without live data lookups or external integrations.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- Minimum value greater than maximum value produces empty interval filter result
- Missing required fields (row_id, document_group, date) causes row rejection
- Null numeric values in the selected field may be excluded from ordering or filtering
- field enum value not one of 'updated_articles' or 'due_articles' causes schema validation error

## How this service works

Knowledge base maintenance — Numeric row ordering + Numeric interval filter: Numeric row ordering + Numeric interval filter 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

Returns up to 2 analytical reports: one with rows numerically sorted by the selected field (updated_articles or due_articles), and one with rows filtered to only those where the selected field value falls within the specified minimum–maximum interval. Reports cover up to 200 input rows and are computed locally without external lookups.
