# Content Reuse Duplicate Key Report + Numeric Row Ordering

> Content Reuse Duplicate Key Report + 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 2026-11-02).

Generates a duplicate key report and numeric row ordering report for supplied content reuse records (reused_blocks, total_blocks) — up to 200 rows, no external lookups.

## 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 content-reuse-duplicate-key-report-numeric-row-ordering-fdc522b4 -d '<json body>'
```

Example prompt: I have a batch of content reuse records — can you run a duplicate key report and numeric row ordering on them? Each row has a row_id, document_group, date, reused_blocks, and total_blocks; order by reused_blocks. Here are the rows: [{"row_id":"row-1","document_group":"group-a","date":"2026-10-01","reused_blocks":10,"total_blocks":1},{"row_id":"row-2","document_group":"group-b","date":"2026-10-02","reused_blocks":20,"total_blocks":2}].

## When to prefer this

Choose this endpoint when you need both a duplicate key audit and numeric row ordering in a single call on a batch of content reuse records (up to 200 rows). It is ideal for data quality checks before ingesting or publishing document reuse datasets, and is cost-effective at $0.01 for two reports. Prefer this over general-purpose analytics when your data specifically has reused_blocks and total_blocks fields and you want offline, local computation with no external lookups or predictions.

## Known failure modes

- Fewer than 1 row supplied — minimum 1 row required
- More than 200 rows supplied — exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) — fails pattern validation
- Missing required fields (row_id, document_group, date, reused_blocks, total_blocks) — request rejected
- Invalid field enum value — must be 'reused_blocks' or 'total_blocks'
- Payment not included or insufficient — x402 payment required ($0.01 USDC)

## How this service works

Content reuse — Duplicate key report + Numeric row ordering: Duplicate key report + Numeric row ordering for supplied content reuse records (reused_blocks, total_blocks). 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 independent analytical reports: (1) a duplicate key report identifying rows with repeated key values across the supplied content reuse records, and (2) a numeric row ordering report ranking rows by the specified field (reused_blocks or total_blocks). Results cover up to 200 supplied rows using local analytical engines with no external data fetched.
