# Sitemap Inventories — Grouped Numeric Summary + Secondary-Measure Weighted Mean

> Sitemap Inventories — Grouped Numeric Summary + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Computes a grouped numeric summary and a secondary-measure weighted mean for sitemap inventory records (listed_urls, fetched_urls) 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 sitemap-inventories-grouped-numeric-summary-secondary-measure-f495407e -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and weighted mean on my sitemap inventory data — I have rows with site_group, date, listed_urls, and fetched_urls fields, and I want to use listed_urls as the primary field? Here are the rows: group-a on 2026-10-01 had 10 listed and 1 fetched, group-b on 2026-10-02 had 20 listed and 2 fetched.

## When to prefer this

Choose this endpoint when you have tabular sitemap inventory data (listed_urls, fetched_urls) already on hand and need two fast, local statistical reports — a grouped numeric summary and a weighted mean — without triggering any live crawl, external lookup, or prediction. It is cost-effective at $0.01 USDC for both reports on up to 200 rows, making it ideal for batch analytical workflows on pre-collected sitemap data.

## Known failure modes

- Missing required fields (row_id, site_group, date, listed_urls, fetched_urls) causes validation error
- More than 200 rows submitted exceeds the row limit
- Date field not matching YYYY-MM-DD pattern causes rejection
- Null values in numeric fields may affect weighted mean calculation
- Invalid enum value for 'field' parameter causes error

## How this service works

Sitemap inventories — Grouped numeric summary + Secondary-measure weighted mean: Grouped numeric summary + Secondary-measure weighted mean 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

Two independent analytical reports: (1) a grouped numeric summary of the supplied sitemap inventory rows segmented by site_group, and (2) a secondary-measure weighted mean calculation using the chosen field (listed_urls or fetched_urls). Results are computed locally without live lookups or external data.
