# Business Website Inventories — Equal-Width Histogram & Weighted Mean Analytics

> Business Website Inventories — Equal-Width Histogram & Weighted Mean Analytics is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Computes an equal-width histogram and a secondary-measure weighted mean for up to 200 business website inventory records (page_count, verified_pages) using local analytical engines.

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 business-website-inventories-equal-width-histogram-weighted-mean-49e80ede -d '<json body>'
```

Example prompt: I have 150 business website inventory records with page_count and verified_pages columns — can you compute an equal-width histogram with 8 bins for page_count and also give me the verified_pages weighted mean, for all my company groups?

## When to prefer this

Choose this endpoint when you need fast, offline statistical analysis of business website inventory data — specifically equal-width histogram binning and secondary weighted mean — without requiring live lookups or external data enrichment. Best suited for batch analysis of up to 200 inventory records where page_count and verified_pages are the key measures.

## Known failure modes

- More than 200 rows submitted — exceeds the maximum row limit
- Missing required row fields (row_id, company_group, date, page_count, verified_pages) — validation error
- Invalid date format (must match YYYY-MM-DD) — schema validation failure
- Bins value outside 1–30 range — rejected by schema
- All values null for the chosen field — unable to compute histogram or weighted mean
- Payment not completed via x402 protocol — request rejected

## How this service works

Business website inventories — Equal-width histogram + Secondary-measure weighted mean: Equal-width histogram + Secondary-measure weighted mean for supplied business website inventories records (page_count, verified_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) an equal-width histogram showing bin ranges and counts for the chosen field (page_count or verified_pages) across up to 200 rows, and (2) a secondary-measure weighted mean, computed using local engines with no external lookups.
