# Archive Retrieval — Trailing Mean Series + Keyed Dataset Comparison

> Archive Retrieval — Trailing Mean Series + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Computes a trailing mean time series and performs a keyed dataset comparison on two sets of archive retrieval records (retrieved_pages, attempted_pages) for 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-trailing-mean-series-keyed-dataset-comparison-07a464d0 -d '<json body>'
```

Example prompt: I have two sets of archive retrieval records across a few site groups with dates and page counts — can you run a trailing mean series on the retrieved_pages field and compare the two datasets side by side for up to 200 rows?

## When to prefer this

Choose this endpoint when you need both a rolling/trailing mean time series and a keyed row-by-row comparison between two archive retrieval datasets in a single low-cost call ($0.01 USDC). Ideal for web archiving or crawl analytics workflows where you want to track trends in page retrieval rates and simultaneously audit differences between two crawl runs or configurations. Use when your data fits within 200 rows and involves the specific archive retrieval schema (retrieved_pages, attempted_pages, site_group, date).

## Known failure modes

- Fewer than 1 row supplied — schema requires minItems: 1
- Row objects missing required fields (row_id, site_group, date, retrieved_pages, attempted_pages) — validation error
- Date values not in YYYY-MM-DD format — pattern validation failure
- More than 200 rows submitted — exceeds maxItems limit
- Invalid field selector (not 'retrieved_pages' or 'attempted_pages') — enum validation error
- Null numeric values may affect trailing mean computation if too many nulls are present

## How this service works

Archive retrieval — Trailing mean series + Keyed dataset comparison: Trailing mean series + Keyed dataset comparison 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 trailing mean time series for the selected numeric field (retrieved_pages or attempted_pages) across the supplied rows, and (2) a keyed dataset comparison between the primary rows and a second dataset (other), highlighting differences by row key. Both reports use local analytical engines with no external lookups. Up to 200 rows per call.
