# Archive Retrieval — String Normalisation + Trailing Mean Series

> Archive Retrieval — String Normalisation + Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Applies string normalisation and computes a trailing mean series on user-supplied 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-string-normalisation-trailing-mean-series-42234803 -d '<json body>'
```

Example prompt: Can you run string normalisation and a trailing mean series with a window of 3 on my archive retrieval data — I have rows with site groups like 'group-a' and 'group-b', dates from 2026-10-01 to 2026-10-04, and I want the analysis on the retrieved_pages field?

## When to prefer this

Choose this endpoint when you have user-supplied archive retrieval tabular data (up to 200 rows) and need both string normalisation of categorical fields and a trailing/rolling mean series over a numeric metric (retrieved_pages or attempted_pages) in a single low-cost call. It is a good fit for offline batch analytical preparation of crawl or web archive datasets where no live lookup or external data is required.

## Known failure modes

- More than 200 rows supplied — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row-level errors
- Null values in the target numeric field may affect trailing mean computation
- Missing required fields (row_id, date, site_group) cause validation failure
- Window size outside 2–200 range rejected by schema validation

## How this service works

Archive retrieval — String normalisation + Trailing mean series: String normalisation + Trailing mean 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

Two analytical reports for the supplied rows: (1) string-normalised versions of the site_group and related text fields, and (2) a trailing mean series computed over the chosen numeric field (retrieved_pages or attempted_pages) using the specified window size, covering up to 200 input rows.
