# Archive Retrieval — Duplicate Key Report + Category Frequencies

> Archive Retrieval — Duplicate Key Report + Category Frequencies is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Analyzes up to 200 archive retrieval records to produce two local analytical reports: a duplicate key report and a category frequency breakdown.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 archive-retrieval-duplicate-key-report-category-frequencies-0ee74310 -d '<json body>'
```

Example prompt: Check this batch of archive retrieval records for duplicate row IDs and give me a frequency count for each site_group — here are 4 rows: row-1 on 2026-10-01 in group-a with 10 retrieved and 1 attempted, row-2 on 2026-10-02 in group-b with 20 retrieved and 2 attempted, row-3 on 2026-10-03 in group-a with 15 retrieved and 3 attempted, and row-4 on 2026-10-04 in group-b with 30 retrieved and 4 attempted.

## When to prefer this

Choose this endpoint when you need both a duplicate key check and a category frequency summary on archive retrieval data (retrieved_pages, attempted_pages fields) in a single $0.01 call. It is ideal for data quality audits before pipeline ingestion, deduplication checks on crawl logs, and quick profiling of site_group distributions — all without any external lookups or live data access. It bundles two analytical reports for one payment, making it cost-efficient compared to running separate checks.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, site_group, date, retrieved_pages, attempted_pages) — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- Empty rows array — minItems constraint violation
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — schema rejection
- Payment not included or insufficient — x402 payment required error

## How this service works

Archive retrieval — Duplicate key report + Category frequencies: Duplicate key report + Category frequencies for supplied archive retrieval records (retrieved_pages, attempted_pages). 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 any repeated row_id values across the submitted rows, and (2) a category frequency table showing how often each site_group value appears in the dataset. Both reports are computed locally from the supplied data with no external lookups. Up to 200 rows supported per call.
