# News Archive Completeness — Record Quality Audit + Exact Row Deduplication

> News Archive Completeness — Record Quality Audit + Exact Row Deduplication 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).

Audits record quality and detects exact duplicate rows in news archive completeness data (indexed_items vs expected_items) for up to 200 rows, returning two independent analytical reports.

## 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 news-archive-completeness-record-quality-audit-exact-row-deduplication-060f3b68 -d '<json body>'
```

Example prompt: Can you audit these news archive completeness records for quality issues and exact duplicates? I have up to 50 rows with fields like row_id, channel_group, date, indexed_items, and expected_items — I need both a record quality audit and a deduplication report.

## When to prefer this

Choose this endpoint when you need to validate and deduplicate news archive completeness records (indexed_items vs expected_items) in a single low-cost call. It is ideal for pre-processing pipelines where data integrity must be confirmed before downstream analysis, and when you have up to 200 rows to inspect at once. Prefer this over generic data-quality tools when your data specifically tracks news indexing completeness by channel group and date.

## Known failure modes

- Fewer than 1 row submitted — request rejected
- More than 200 rows submitted — exceeds batch limit, request rejected
- Missing required fields (row_id, channel_group, date, indexed_items, expected_items) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema validation failure
- row_id exceeds 80-character limit — schema validation failure
- numeric values outside allowed range (±1,000,000,000,000) — schema validation failure
- Payment of 0.01 USDC not provided or declined — 402 payment required error

## How this service works

News archive completeness — Record quality audit + Exact row deduplication: Record quality audit + Exact row deduplication for supplied news archive completeness records (indexed_items, expected_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 record quality audit covering field completeness, value ranges, and anomalies for indexed_items and expected_items; (2) an exact row deduplication report identifying rows with identical field values across the submitted dataset. No external data is fetched — analysis is performed entirely on the submitted rows.
