# Sitemap Inventories – Secondary-Measure Weighted Mean + Explicit Missing-Value Fill

> Sitemap Inventories – Secondary-Measure Weighted Mean + Explicit Missing-Value Fill 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 a secondary-measure weighted mean and fills missing values in sitemap inventory records (listed_urls, fetched_urls) for up to 200 rows, producing two analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-explicit-missing-c1ed5fa9 -d '<json body>'
```

Example prompt: Can you calculate the secondary-measure weighted mean for listed_urls across these 4 sitemap inventory rows — filling any missing values using median imputation — and give me both analytical reports? Rows: site_group A on 2026-10-01 with 10 listed and 1 fetched, site_group B on 2026-10-02 with 20 listed and 2 fetched, site_group A on 2026-10-03 with 15 listed and null fetched, site_group B on 2026-10-04 with 30 listed and 4 fetched.

## When to prefer this

Choose this endpoint when you have tabular sitemap inventory data with listed_urls and/or fetched_urls columns, need to handle missing values explicitly before aggregation, and want a weighted mean computed locally without any live web lookup or external data enrichment. It is ideal for SEO teams auditing sitemap crawl coverage across site groups over time, especially when data quality issues (nulls) are present. It is not suitable for real-time sitemap fetching, prediction, or datasets exceeding 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- Missing required fields (row_id, site_group, date) causes schema rejection
- Field enum value outside [listed_urls, fetched_urls] returns error
- Method enum value outside [zero, mean, median] returns error
- All values null for selected field may yield undefined weighted mean
- Numeric values outside ±1,000,000,000,000 boundary rejected

## How this service works

Sitemap inventories — Secondary-measure weighted mean + Explicit missing-value fill: Secondary-measure weighted mean + Explicit missing-value fill 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 local analytical reports per call: one containing the secondary-measure weighted mean of the chosen field (listed_urls or fetched_urls) across the submitted rows, and one with explicit missing-value fills applied using the selected method (zero, mean, or median), covering up to 200 input rows total.
