# Sitemap Inventories — Secondary-Measure Weighted Mean + Keyed Dataset Comparison

> Sitemap Inventories — Secondary-Measure Weighted Mean + 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 secondary-measure weighted mean and performs a keyed dataset comparison on two supplied sitemap inventory datasets (listed_urls, fetched_urls) for up to 200 rows each.

## 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 sitemap-inventories-secondary-measure-weighted-mean-keyed-dataset-8e19bf02 -d '<json body>'
```

Example prompt: I have two sets of sitemap inventory data — each with up to 50 rows tracking listed_urls and fetched_urls per site group — can you compute a secondary-measure weighted mean for the listed_urls field and also run a keyed comparison between the two datasets?

## When to prefer this

Choose this endpoint when you need both a weighted mean statistical summary and a keyed row-level comparison between two sitemap inventory datasets in a single API call for up to 200 rows. It is purpose-built for sitemap crawl analytics (listed_urls, fetched_urls) and avoids the need for live lookups or external data sources. Prefer it over generic analytics services when your data is already structured with row_id, site_group, and date keys and you want a cost-effective dual-report output ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows supplied — request rejected or truncated
- Missing required fields (row_id, site_group, date, listed_urls, fetched_urls) — validation error
- Date field not matching YYYY-MM-DD pattern — schema validation failure
- Null values in numeric fields may affect weighted mean computation
- Mismatched keys between primary and comparison datasets produce empty comparison results
- Payment not included or insufficient — x402 payment required error

## How this service works

Sitemap inventories — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison for supplied sitemap inventories records (listed_urls, fetched_urls). 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 secondary-measure weighted mean of the chosen field (listed_urls or fetched_urls) across the supplied rows, and (2) a keyed dataset comparison between the primary and secondary supplied datasets, highlighting differences per row_id/site_group/date key. Results are computed locally with no external lookups.
