# Archive Retrieval — Numeric Distribution + Base-100 Series

> Archive Retrieval — Numeric Distribution + Base-100 Series 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).

Computes numeric distribution statistics and a base-100 index series for supplied archive retrieval metrics (retrieved_pages, attempted_pages) across up to 200 rows.

## 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-numeric-distribution-base-100-series-64777197 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and a base-100 index series on my archive retrieval data? I have 50 rows with retrieved_pages and attempted_pages by date and site group — analyze the retrieved_pages field and start the base index at row 0.

## When to prefer this

Choose this endpoint when you have pre-collected archive retrieval data (retrieved_pages, attempted_pages) and need both a statistical distribution and a base-100 indexed trend series in a single low-cost call. It is ideal for offline or batch analytical workflows where no live data lookup is needed and you want two complementary views — spread and indexed trajectory — on the same dataset for up to 200 rows.

## Known failure modes

- Missing required fields (row_id, date, retrieved_pages, attempted_pages) causes validation error
- Submitting more than 200 rows exceeds the maxItems limit and will be rejected
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Providing a base_index value outside 0–199 results in a schema error
- Null numeric values may affect distribution statistics or index calculation

## How this service works

Archive retrieval — Numeric distribution + Base-100 series: Numeric distribution + Base-100 series 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 analytical reports: (1) a numeric distribution summarizing the frequency and spread of values in the selected field (retrieved_pages or attempted_pages), and (2) a base-100 index series expressing each row's value relative to the chosen base row, enabling trend comparison. Both reports cover up to 200 input rows and are computed locally without any external data lookup.
